MULTILAYER CRYSTALLIZABLE SHRINKABLE FILM AND SHEET FIELD OF THE INVENTION [0001] The present disclosure relates to multilayer crystallizable shrinkable films and/or sheet(s) comprising amorphous copolyester compositions and crystallizable copolyester composition which comprise residues of terephthalic acid, neopentyl glycol (NPG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), diethylene glycol (DEG) and which incorporate recycled PET, in certain compositional ranges having certain advantages and improved properties including recyclability. BACKGROUND OF THE INVENTION [0002] There is a commercial need for multilayer shrink films that have at least one of the following desirable shrink film properties: (1) low onset shrinkage temperature, (2) a shrinkage percentage which increases gradually and in a controlled manner with increasing temperature over the temperature range where shrinkage occurs, (3) a shrink force low enough to prevent crushing of the underlying container, (4) a high ultimate shrinkage (shrinkage at the highest temperature), e.g. 50% or greater shrinkage in the main shrinkage direction at 95°C, (5) low shrinkage in the direction orthogonal to the high shrinkage direction, (6) improved film toughness so as to prevent unnecessary fracturing, breaking, tearing, splitting, bubbling, or wrinkling of the film during manufacture and prior to and after shrinkage, (6) made from recycle content and (7) recyclability. BRIEF SUMMARY OF THE INVENTION [0003] It has been found that certain combinations of glycol monomers in a shrink film resin composition can produce a multilayer film with good shrink film performance and also be crystallizable such that it does not negatively impact the recycling of the PET flake during recycling. These multilayer crystallizable shrink films can be processed with the PET bottle and end up as a component in the recyclable PET flake leaving the recycling process. It has also been found that the choice and quantity of specific combinations of glycol monomers are important to produce multilayer films with good shrink film properties and to produce a multilayer film that is crystallizable. The optimized polyester resin compositions and blends of this disclosure are amorphous but crystallizable. As such, they exhibit good properties in film applications including as shrink films, but they have high strain induced crystalline melting points, so they provide compatibility in recycling processes. The multilayer shrink film labels of the present disclosure do not have to be removed during the recycle process, and they do not impact the process. [0004] Historically, some crystallizable films may present processing challenges. In some instances, crystallizable films may exhibit high on-set shrink temperatures and a high shrink rate. Because of these features, the crystallizable films are often not compatible in some applications; for example, with labelling HDPE containers in a hot air tunnel. The high onset shrinkage temperature does not allow the crystallizable films to shrink prior to expansion of the HDPE container and after the bottle leaves the shrink tunnel, the label is likely to be loose. Additionally, the high shrink rate will often create wrinkles during the shrink process in a hot air tunnel. [0005] In other instances, crystallizable films may have a high shrink rate. So, if they are used in applications as a container label, the high shrink rate can cause wrinkles in the film as well as distort the container’s shape depending on its design, especially in applications with thin bottles or bottles with poor modulus. The multilayer crystallizable films of the present disclosure provide a solution for these processing challenges of high on-set shrink temperatures and high shrink rate. [0006] The multilayer crystallizable films of the present disclosure also address some of the sustainability concerns and requirements for the incorporation of recycled content into heat shrinkable films. Recycled PET (rPET) is incorporated directly into the multilayer crystallizable films of the present disclosure. Historically, films containing a large amount of rPET material tend to have inferior film properties when compared to films without any rPET. However, in the present disclosure, the optimized blend ratios and multilayer configurations provide the benefits of both the inclusion of rPET and the inclusion of the crystallizable resins. The multilayer crystallizable films of the present disclosure have improved shrink characteristics even with the inclusion of rPET and they are also compatible with the PET recycle stream. [0007] Moreover, the multilayer crystallizable films of the present disclose affords the additional advantages, for instance of lower shrink force and the incorporation of rPET without affecting other properties. [0008] The multilayer films must meet a variety of fitness for use criteria to perform in this application. The multilayer films must be tough, must shrink in a controlled manner, and must provide enough shrink force to hold itself on the bottle without crushing the contents. In addition, when these labels are applied to polyester containers, the multilayer polyester shrink film labels must not interfere with the recycling process of the bottle. The multilayer shrink films of the present disclosure are advantageous because the label can be recycled with the bottle or container. As such, the entire bottle, including the label, can be recycled and converted into new products without creating additional handling requirements or creating new environmental issues. Thermoshrinkable films have been made from a variety of raw materials to meet a range of material demands. This disclosure describes unique and unexpected effects measured with certain monomers combinations for shrink film resin compositions. [0009] Polyester shrink film compositions have been used commercially as shrink film labels for food, beverage, personal care, household goods, etc. Often, these shrink films are used in combination with a clear polyethylene terephthalate (PET) bottle or container. The total package (bottle plus label) is then placed in the recycling process. In a typical recycling center, the PET and the shrink film material often end up together at the end of the process due to similarities in composition and density. Drying of the PET flake is required to remove residual water that remains with the PET through the recycling process. Typically, PET is dried at temperatures above 150°C, and in some instances above 200°C. At those temperatures, typical polyester shrink film resins will soften and become sticky, often creating clumps with PET flakes. These clumps must be removed before further processing. These clumps reduce the yield of PET flake from the process and create an additional handling step. [0010] Also, it has been found that certain combinations of glycol monomers in a film or sheet resin composition can produce film or sheet with good performance properties and is also crystallizable such that it does not impact the recycling of the PET flake. These crystallizable film or sheet resins can be processed with recycled PET and end up as a component in the recyclable PET flake leaving the recycling process. It has also been found that the choice and quantity of specific combinations of glycol monomers are important to produce films or sheet with good performance properties and to produce a film or sheet that is crystallizable. The optimized polyester resin compositions of this disclosure are amorphous but crystallizable. As such, they exhibit good properties in film or sheet applications including as molded, thermoformed, or shaped parts and/or articles, but they have high strain induced crystalline melting points, so they can be recycled with PET. The films or sheet of the present disclosure do not have to be removed during the recycle process, and they do not impact the recycle process.

DETAILED DESCRIPTION [0029] The present disclosure may be understood more readily by reference to the following detailed description of certain embodiments of the disclosure and the working examples. In accordance with the purpose(s) of this disclosure, certain embodiments of the disclosure are described in the Summary of the Invention and are further described herein below. Also, other embodiments of the disclosure are described herein. [0030] Heat-shrinkable plastic films are used as coverings, to hold objects together, and as an outer wrapping for bottles, cans and other kinds of containers. For example, such films are used for covering the cap, neck, shoulder or bulge of bottles or the entire bottle; for the purpose of labeling, protection, parceling, or increasing the value of the product; and for other reasons. In addition, such films may be used as a covering to package such objects as boxes, bottles, boards, rods, or notebooks together in groups, and such films may also be attached closely as a wrapping. The uses mentioned above take advantage of the shrinkability and the internal shrink stress of the film. [0031] Historically, Poly(vinyl chloride) (PVC) films dominated the shrink film market. However, polyester films have become a significant alternative because polyester films do not possess the environmental problems associated with PVC films. Polyester shrink films ideally would have properties very similar to PVC films so that the polyester films can serve as a “drop-in” replacement films and can be processed in existing shrink tunnel equipment. PVC film properties that are desired for duplication include the following: (1) a relatively low shrinkage onset temperature, (2) a total shrinkage which increases gradually and in a controlled manner with increasing temperature, (3) a low shrink force to prevent crushing of the underlying container, (4) a high total shrinkage (for example, 50% or greater), (5) an inherent film toughness so as to prevent unnecessary tearing and splitting of the film prior to and after shrinkage, and (6) a high strain induced crystalline melt temperature. [0032] This disclosure describes unique and unexpected effects measured with certain monomers combinations that improves the recyclability of the multilayer polyester shrink film labels. [0033] Shrink film compositions are used commercially as shrink film labels for food, beverage, personal care, household goods, etc. Often, these shrink films are used in combination with a clear polyethylene terephthalate (PET) bottle or container. The total package (bottle plus label) is then placed in the recycling process. In a typical recycling center, the PET and the shrink film material often end up together at the end of the process due to similarities in composition and density. Drying of the PET flake is required to remove residual water that remains with the PET through the recycling process. Typically, PET is dried at temperatures above 150°C, and in some instances above 200°C. At those temperatures, typical polyester shrink film resins will soften and become sticky, often creating clumps with PET flakes. These clumps must be removed before further processing. These clumps reduce the yield of PET flake from the process and create an additional handling step. [0034] It has been found that certain combinations of glycol monomers in a shrink film resin composition can produce a film with good shrink film performance and also be crystallizable such that it does not impact the recycling of the PET flake during recycling. These crystallizable shrink film resins can be processed with the PET bottle and end up as a component in the recyclable PET flake leaving the recycling process. It has also been found that the choice and quantity of specific combinations of glycol monomers are important to produce films with good shrink film properties and to produce a film that is crystallizable. [0035] There is no limitation on the recycled polyethylene terephthalate (rPET) that may be used in the blend compositions of the present disclosure. In one embodiment the rPET is mechanically recycled. In one embodiment the rPET is produced from chemically recycled monomers (produced by any known methods of depolymerization). In one embodiment, the rPET may have minor modifications such as with up to 5 mole% of isophthalic acid and/or up to 5 mole % of CHDM or other diols. In one embodiment, the recycled PET (rPET) can be virtually any "waste" industrial or post-consumer PET. In one embodiment, the rPET useful in the blend compositions of the present disclosure may be post-consumer recycled PET. In one embodiment, the rPET is post-industrial recycled PET. In one embodiment, the rPET is post-consumer PET from soft drink bottles. In one embodiment, scrap PET fibers, scrap PET films, and poor- quality PET polymers are also suitable sources of rPET. In one embodiment, the recycled PET comprises substantially PET, although other copolyesters can also be used, particularly where they have a similar structure as PET, such as PET copolymers or the like. In one embodiment, the rPET is clean. In one embodiment, the rPET is substantially free of contaminants. In one embodiment, the rPET may be in the form of flakes. [0036] In one embodiment, up to about 50% by weight rPET can be incorporated into the blend compositions of the present disclosure. In one embodiment, up to about 40% by weight rPET can be incorporated into the blend compositions of the present disclosure. In one embodiment, up to about 30% by weight rPET can be incorporated into the blend compositions of the present disclosure. In one embodiment, up to about 20% by weight rPET can be incorporated into the blend compositions of the present disclosure. In one embodiment, the rPET/copolyester blend is 0.1-50 wt% of rPET. In one embodiment, the rPET/copolyester blend is 1-50 wt% of recycled polyethylene terephthalate (rPET). In one embodiment, the rPET/copolyester blend is 10-50 wt% of recycled polyethylene terephthalate (rPET). In one embodiment, the rPET/copolyester blend is 15-50 wt% of recycled polyethylene terephthalate (rPET).

In one embodiment rPET/copolyester blend is 20-40 wt% of recycled polyethylene terephthalate (rPET) and 30-40 wt% of at least one copolyester. In one embodiment rPET/copolyester blend is 1-50 wt% of recycled polyethylene terephthalate (rPET) and 50-99 wt% of at least one copolyester. [0037] The term “polyester”, as used herein, is intended to include “copolyesters” and is understood to mean a synthetic polymer prepared by the reaction of one or more difunctional carboxylic acids and/or multifunctional carboxylic acids with one or more difunctional hydroxyl compounds and/or multifunctional hydroxyl compounds, for example, branching agents. Typically, the difunctional carboxylic acid can be a dicarboxylic acid and the difunctional hydroxyl compound can be a dihydric alcohol, for example, glycols and diols. The term “glycol” as used herein includes, but is not limited to, diols, glycols, and/or multifunctional hydroxyl compounds, for example, branching agents. Alternatively, the difunctional carboxylic acid may be a hydroxy carboxylic acid, for example, p-hydroxybenzoic acid, and the difunctional hydroxyl compound may have an aromatic nucleus bearing 2 hydroxyl substituents, for example, hydroquinone. The term “residue”, as used herein, means any organic structure incorporated into a polymer through a polycondensation and/or an esterification reaction from the corresponding monomer. The term “repeating unit”, as used herein, means an organic structure having a dicarboxylic acid residue and a diol residue bonded through an ester group. Thus, for example, the dicarboxylic acid residues may be derived from a dicarboxylic acid monomer or its associated acid halides, esters, salts, anhydrides, and/or mixtures thereof. Furthermore, as used herein, the term “diacid” includes multifunctional acids, for example, branching agents. As used herein, therefore, the term “dicarboxylic acid” is intended to include dicarboxylic acids and any derivative of a dicarboxylic acid, including its associated acid halides, esters, half-esters, salts, half-salts, anhydrides, mixed anhydrides, and/or mixtures thereof, useful in a reaction process with a diol to make a polyester. As used herein, the term “terephthalic acid” is intended to include terephthalic acid itself and residues thereof as well as any derivative of terephthalic acid, including its associated acid halides, esters, half-esters, salts, half-salts, anhydrides, mixed anhydrides, and/or mixtures thereof or residues thereof useful in a reaction process with a diol to make a polyester. [0038] The polyesters used in the present disclosure typically can be prepared from dicarboxylic acids and diols which react in substantially equal proportions and are incorporated into the polyester polymer as their corresponding residues. The polyesters of the present disclosure, therefore, can contain substantially equal molar proportions of acid residues (100 mole%) and diol (and/or multifunctional hydroxyl compound) residues (100 mole%) such that the total moles of repeating units is equal to 100 mole%. The mole percentages provided in the present disclosure, therefore, may be based on the total moles of acid residues, the total moles of diol residues, or the total moles of repeating units. For example, a polyester containing 10 mole% isophthalic acid, based on the total acid residues, means the polyester contains 10 mole% isophthalic acid residues out of a total of 100 mole% acid residues. Thus, there are 10 moles of isophthalic acid residues among every 100 moles of acid residues. In another example, a polyester containing 25 mole% 1,4- cyclohexanedimethanol, based on the total diol residues, means the polyester contains 25 mole% 1,4-cyclohexanedimethanol residues out of a total of 100 mole% diol residues. Thus, there are 25 moles of 1,4-cyclohexanedimethanol residues among every 100 moles of diol residues. [0039] In certain embodiments, terephthalic acid or an ester thereof, for example, dimethyl terephthalate or a mixture of terephthalic acid residues and an ester thereof can make up a portion or all of the dicarboxylic acid component used to form the polyesters useful in the present disclosure. In certain embodiments, terephthalic acid residues can make up a portion or all of the dicarboxylic acid component used to form the polyesters useful in this disclosure. For the purposes of this disclosure, the terms “terephthalic acid” and “dimethyl terephthalate” are used interchangeably herein. In one embodiment, dimethyl terephthalate is part or all of the dicarboxylic acid component used to make the polyesters useful in the present disclosure. In embodiments, ranges of from 70 to 100 mole%; or 80 to 100 mole%; or 90 to 100 mole%; or 95 to 100 mole%; or 99 to 100 mole%; or 99.9 to 100 mole%; or 100 mole% terephthalic acid and/or dimethyl terephthalate and/or mixtures thereof may be used. [0040] In addition to terephthalic acid, the dicarboxylic acid component of the polyesters useful in the present disclosure can comprise up to 30 mole%, up to 20 mole%, up to 10 mole%, up to 5 mole%, or up to 1 mole% of one or more modifying aromatic dicarboxylic acids. Yet another embodiment contains 0 mole% modifying aromatic dicarboxylic acids. Thus, if present, it is contemplated that the amount of one or more modifying aromatic dicarboxylic acids can range from any of these preceding endpoint values including, for example, 0.01 to 10 mole%, from 0.01 to 5 mole% and from 0.01 to 1 mole%. In one embodiment, modifying aromatic dicarboxylic acids that may be used in the present disclosure include but are not limited to those having up to 20 carbon atoms, and which can be linear, para-oriented, or symmetrical. Examples of modifying aromatic dicarboxylic acids which may be used in this disclosure include, but are not limited to, isophthalic acid, 4,4′- biphenyldicarboxylic acid, 1,4-, 1,5-, 2,6-, 2,7-naphthalenedicarboxylic acid, and trans-4,4′-stilbenedicarboxylic acid, and esters thereof. In one embodiment, the modifying aromatic dicarboxylic acid is isophthalic acid. [0041] The carboxylic acid component of the polyesters useful in the present disclosure can be further modified with up to 10 mole%, such as up to 5 mole% or up to 1 mole% of one or more aliphatic dicarboxylic acids containing 2-16 carbon atoms, for example, cyclohexanedicarboxylic, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic and/or dodecanedioic dicarboxylic acids. Certain embodiments can also comprise 0.01 to 10 mole%, such as 0.1 to 10 mole%, 1 or 10 mole%, 5 to 10 mole% of one or more modifying aliphatic dicarboxylic acids. Yet another embodiment contains 0 mole% modifying aliphatic dicarboxylic acids. The total mole% of the dicarboxylic acid component is 100 mole%. In one embodiment, adipic acid and/or glutaric acid are provided in the modifying aliphatic dicarboxylic acid component of the polyesters and are useful in the present disclosure. [0042] Esters of terephthalic acid and the other modifying dicarboxylic acids or their corresponding esters and/or salts may be used instead of the dicarboxylic acids. Suitable examples of dicarboxylic acid esters include, but are not limited to, the dimethyl, diethyl, dipropyl, diisopropyl, dibutyl, and diphenyl esters. In one embodiment, the esters are chosen from at least one of the following: methyl, ethyl, propyl, isopropyl, and phenyl esters. [0043] In another embodiment, at least a portion of the residues derived from dicarboxylic acids and glycols as set forth herein, are derived from recycled monomeric species such as recycled dimethylterephthalate (rDMT), recycled terephthalic acid(rTPA), recycled dimethylisopthalate(rDMI), recycled ethylene glycol(rEG), recycled cyclohexanedimethanol (rCHDM), recycled neopentyl glycol(rNPG), recycled 2,2,4,4-tetramethyl-1,3- cyclobutanediol(rTMCD), and recycled diethylene glycol(rDEG). Such recycled monomeric species can be obtained from known methanolysis or glycolysis reactions which are utilized to depolymerize various post-consumer recycled polyesters and copolyesters. Similarly, recycled poly(ethylene terephthalate) (rPET) can be utilized as a feedstock (for the dicarboxylic acid and glycol components) in the manufacturing of polyesters of the invention having recycle content. Accordingly, in another embodiment, the polyester compositions of the invention comprise at least a portion of the dicarboxylic acid residues and/or glycol residues are derived from (i) recycled monomeric species chosen from rDMT, rTPA, rDMI, rEG, rCHDM, rDEG, rTMCD, rNPG and (ii) rPET. [0044] In one embodiment, the diol component of the polyester compositions useful in the present disclosure can comprise 1,4- cyclohexanedimethanol. In another embodiment, the diol component of the polyester compositions useful in the present disclosure comprise 1,4- cyclohexanedimethanol and 1,3-cyclohexanedimethanol.

[0062] The glass transition temperature (Tg) of the polyesters is determined using a TA DSC 2920 from Thermal Analyst Instrument at a scan rate of 20ºC/min. [0063] In certain embodiments, the multilayer oriented films or multilayer shrink films of this disclosure comprise polyesters/polyester compositions wherein the polyester has a Tg of 60 to 80°C; 70 to 80°C; or 65 to 80°C; or 65 to 75°C. In certain embodiments, these Tg ranges can be met with or without at least one plasticizer being added during polymerization. [0064] In embodiments of the present disclosure, certain multilayer oriented films and/or multilayer shrinkable films comprising the polyesters and/or polyester compositions useful in this disclosure can have a unique combination of all of the following properties: good stretchability, controlled shrinkage properties, certain toughness, certain inherent viscosities, certain glass transition temperatures (Tg), certain strain induced crystalline melting points, certain flexural modulus, certain densities, certain tensile modulus, certain surface tension, good melt viscosity, good clarity, good color, and recyclability. [0065] In one embodiment, certain polyester compositions useful in this disclosure can be visually clear. The term “visually clear” is defined herein as an appreciable absence of cloudiness, haziness, and/or muddiness, when inspected visually. [0066] The polyester portion of the polyester compositions useful in this disclosure can be made by processes known from the literature, for example, by processes in homogenous solution, by transesterification processes in the melt, and by two phase interfacial processes. Suitable methods include, but are not limited to, the steps of reacting one or more dicarboxylic acids with one or more diols at a temperature of 100°C. to 315°C. at a pressure of 0.1 to 760 mm Hg for a time sufficient to form a polyester. See U.S. Pat. No.3,772,405 for methods of producing polyesters, the disclosure regarding such methods is hereby incorporated herein by reference. [0067] The polyester in general may be prepared by condensing the dicarboxylic acid or dicarboxylic acid ester with the diol in the presence of a catalyst at elevated temperatures increased gradually during the course of the condensation up to a temperature of about 225°C to 310°C., in an inert atmosphere, and conducting the condensation at low pressure during the latter part of the condensation, as described in further detail in U.S. Pat. No. 2,720,507 incorporated herein by reference herein. [0068] In some embodiments, during the process for making the polyesters useful in the present disclosure, certain agents which colorize the polymer can be added to the melt including toners or dyes. In one embodiment, a bluing toner is added to the melt in order to reduce the b* of the resulting polyester polymer melt phase product. Such bluing agents include blue inorganic and organic toner(s) and/or dyes. In addition, red toner(s) and/or dyes can also be used to adjust the a* color. Organic toner(s), e.g., blue and red organic toner(s), such as those toner(s) described in U.S. Pat. Nos.5,372,864 and 5,384,377, which are incorporated by reference in their entirety, can be used. The organic toner(s) can be fed as a premix composition. The premix composition may be a neat blend of the red and blue compounds or the composition may be pre- dissolved or slurried in one of the polyester's raw materials, e.g., ethylene glycol. [0069] The total amount of toner components added can depend on the amount of inherent yellow color in the base polyester and the efficacy of the toner. In one embodiment, a concentration of up to about 15 ppm of combined organic toner components and a minimum concentration of about 0.5 ppm can be used. In one embodiment, the total amount of bluing additive can range from 0.5 to 10 ppm. In an embodiment, the toner(s) can be added to the esterification zone or to the polycondensation zone. Preferably, the toner(s) are added to the esterification zone or to the early stages of the polycondensation zone, such as to a prepolymerization reactor. [0070] The present disclosure further relates to polymer blends. In one embodiment, the polymer blend comprises: (a) from 5 to 95 weight % of the polyester compositions of the disclosure described herein; and (b) from 5 to 95 weight % of at least one polymeric component. [0071] Suitable examples of the polymeric components include, but are not limited to, nylon; polyesters different than those described herein; polyamides such as ZYTEL® from DuPont; polystyrene; polystyrene copolymers; styrene acrylonitrile copolymers; acrylonitrile butadiene styrene copolymers; poly(methyl methacrylate); acrylic copolymers; poly(ether-imides) such as ULTEM® (a poly(ether-imide) from General Electric); polyphenylene oxides such as poly(2,6-dimethylphenylene oxide) or poly(phenylene oxide)/polystyrene blends such as NORYL 1000® (a blend of poly(2,6- dimethylphenylene oxide) and polystyrene resins from General Electric); polyphenylene sulfides; polyphenylene sulfide/sulfones; poly(ester- carbonates); polycarbonates such as LEXAN® (a polycarbonate from General Electric); polysulfones; polysulfone ethers; and poly(ether-ketones) of aromatic dihydroxy compounds; or mixtures of any of the foregoing polymers. In one embodiment, aliphatic-aromatic polyesters can be excluded from the polyester compositions useful in this disclosure. The following polyesters, which can be blended to make the polyester compositions of this disclosure, can be excluded as the polymeric components used in additional blending if such blending exceeds the compositional ranges of the disclosure: polyethylene terephthalate (PET), glycol modified PET (PETG), glycol modified poly(cyclohexylene dimethylene terephthalate) (PCTG), poly(cyclohexylene dimethylene terephthalate) (PCT), acid modified poly(cyclohexylene dimethylene terephthalate) (PCTA), poly(butylene terephthalate) and/or diethylene glycol modified PET (EASTOBOND™ copolyester). [0072] The blends can be prepared by conventional processing techniques known in the art, such as melt blending or solution blending. [0073] In embodiments, the polyester compositions and the polymer blend compositions can also contain from 0.01 to 25% by weight of the overall composition common additives such as colorants, toner(s), dyes, mold release agents, flame retardants, plasticizers, glass bubbles, nucleating agents, stabilizers, including but not limited to, UV stabilizers, thermal stabilizers, and/or reaction products thereof, fillers, and impact modifiers. Examples of commercially available impact modifiers include, but are not limited to, ethylene/propylene terpolymers, functionalized polyolefins such as those containing methyl acrylate and/or glycidyl methacrylate, styrene-based block copolymeric impact modifiers, and various acrylic core/shell type impact modifiers. Residues of such additives are also contemplated as part of the polyester composition. [0074] Reinforcing materials may be added to the compositions useful in this disclosure. The reinforcing materials may include, but are not limited to, carbon filaments, silicates, mica, clay, talc, titanium dioxide, Wollastonite, glass flakes, glass beads and fibers, and polymeric fibers and combinations thereof. In one embodiment, the reinforcing materials include glass, such as, fibrous glass filaments, mixtures of glass and talc, glass and mica, and glass and polymeric fibers. [0075] In one embodiment, the multilayer films and the multilayer shrink films according to the present disclosure may contain from 0.01 to 10 weight percent of the polyester plasticizer. In one embodiment, the multilayer shrink films can contain from 0.1 to 5 weight percent of the polyester plasticizer. Generally, the multilayer shrink films can contain from 90 to 99.99 weight percent of the copolyester. In certain embodiments, the multilayer shrink films can contain from 95 to 99.9 weight percent of the copolyester. [0076] In one aspect, the present disclosure relates to multilayer shrink film(s) and molded article(s) of this disclosure comprising the polyester compositions and/or polymer blends useful in this disclosure. The methods of forming the polyesters and/or blends into film(s) and/or sheet(s) are well known in the art. Examples of film(s) and/or sheet(s) useful the present disclosure include but not are limited to extruded film(s) and/or sheet(s), compression molded film(s), calendered film(s) and/or sheet(s), solution casted film(s) and/or sheet(s). In one aspect, methods of making film and/or sheet useful to produce the shrink films of the present disclosure include but are not limited to extrusion, compression molding, calendering, and solution casting. [0077] In one embodiment, the polyester compositions useful in this disclosure are made into film using any method known in the art to produce films from polyesters, for example, solution casting, extrusion, compression molding, or calendering. [0078] In one embodiment, the as-formed film is then oriented in one or more directions (e.g., monoaxially and/or biaxially oriented film). This orientation of the film can be performed by any method known in the art using standard orientation conditions. For example, the oriented films of the disclosure can be made from films having a thickness of about 100 to 400 microns, for example, extruded, cast or calendered films, which can be oriented at a ratio of 5:1 to 3:1 at a temperature of from Tg to Tg +55°C or from 70°C to 125°C, for example, at a ratio of 5:1 or of 3:1 at a temperature from 70°C to 100°C, and which can be oriented to a thickness of 20 to 80 microns. In one embodiment, the orientation of the initial pre-shrunk film can be performed on a tenter frame according to these orientation conditions. [0079] The shrink films of the present disclosure can have an onset of shrinkage temperature of from about 55 to about 80°C, or about 55 to about 75°C, or about 55 to about 70°C. Shrink initiation temperature is the temperature at which the onset of shrinking occurs. [0080] In certain embodiments, the polyester compositions useful in the present disclosure can have densities of 1.6 g/cc or less, or 1.5 g/cc or less, or 1.4 g/cc or less, or 1.1 g/cc to 1.5 g/cc, or 1.2 g/cc to 1.4 g/cc, or 1.2 g/cc to 1.35 g/cc. [0081] In one embodiment, the density of the films is reduced by introducing many small voids or holes into the film or shaped article. This process is called “voiding” and may also be referred to as “cavitating” or “microvoiding”. Voids are obtained by incorporating about 1 to about 50 weight% of small organic or inorganic particles (including glass microspheres) or "inclusions" (referred in the art as “voiding” or “cavitation” agents) into a matrix polymer and orienting the polymer by stretching in at least one direction. During stretching, small cavities or voids are formed around the voiding agent. When voids are introduced into polymer films, the resulting voided film not only has a lower density than the non-voided film, but also becomes opaque and develops a paper-like surface. This surface also has the advantage of increased printability; that is, the surface is capable of accepting many inks with a substantially greater capacity over a non-voided film. Typical examples of voided films are described in U.S. Patent No.’s 3,426,754; 3,944,699; 4,138,459; 4,582,752; 4,632,869; 4,770,931; 5,176,954; 5,435,955; 5,843,578; 6,004,664; 6,287,680; 6,500,533; 6,720,085; U.S. Patent Application Publication No.’s 2001/0036545; 2003/0068453; 2003/0165671; 2003/0170427; Japan Patent Application No.’s 61-037827; 63-193822; 2004- 181863; European Patent No.0581970 B1, and European Patent Application No.0214859 A2. [0082] In certain embodiments, the extruded multilayer films are oriented while they are stretched. The oriented multilayer films or multilayer shrinkable films of the present disclosure can be made from films having any thickness depending on the desired end-use. The desirable conditions are, in one embodiment, where the oriented films and/or shrinkable films can be printed with ink for applications including labels, photo films which can be adhered to substrates such as paper, and/or other applications that it may be useful in. It may be desirable to coextrude the polyesters useful in the present disclosure with another polymer, such as PET, to make the films useful in making the oriented films and/or shrink films of this disclosure. One advantage of doing the latter is that a tie layer may not be needed in some embodiments. [0083] In one embodiment, the monoaxially and biaxially oriented films of the present disclosure can be made from films having a thickness of about 100 to 400 microns, for example, extruded, cast or calendered films, which can be stretched at a ratio of 6.5:1 to 3:1 at a temperature of from the Tg of the film to the Tg + 55°C., and which can be stretched to a thickness of 20 to 80 microns. In one embodiment, the orientation of the initial as-extruded film can be performed on a tenter frame according to these orientation conditions. The shrink films of the present disclosure can be made from the oriented films of this disclosure. [0084] In certain embodiments, the shrink films of the present disclosure have gradual shrinkage with little to no wrinkling. In certain embodiments, the shrink films of the present disclosure have no more than 40% shrinkage in the transverse direction per 5°C temperature increase increment. [0085] In certain embodiments of the present disclosure, the shrink films of this disclosure have shrinkage in the machine direction of from 10% or less, or 5% or less, or 3% or less, or 2% or less, or no shrinkage when immersed in water at 65°C for 10 seconds. In certain embodiments of the present disclosure, the shrink films of this disclosure have shrinkage in the machine direction of from -10% to 10%, -5% to 5%, or -5% to 3%, or -5% to 2%, or -4% to 4%, or -3% to 4% or -2% to 4%, or -2% to 2.5%, or -2% to 2%, or 0 to 2%, or no shrinkage, when immersed in water at 65°C for 10 seconds. Negative machine direction shrinkage percentages here indicate machine direction growth. Positive machine direction shrinkages indicate shrinkage in the machine direction. [0086] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure have shrinkage in the main shrinkage direction of from 50% or greater, or 60% or greater, or 70% or greater, when immersed in water at 95°C for 10 seconds. [0087] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure have shrinkage in the main shrinkage direction in the amount of 50 to 90% and shrinkage in the machine direction of 10% or less, or from -10% to 10%, when immersed in water at 95°C for 10 seconds. [0088] In one embodiment, the polyesters useful in the present disclosure are made into films using any method known in the art to produce films from polyesters, for example, solution casting, extrusion, compression molding, or calendaring. The as-extruded (or as-formed) film is then oriented in one or more directions (e.g., monoaxially and/or biaxially oriented film). This orientation of the films can be performed by any method known in the art using standard orientation conditions. For example, the monoaxially oriented films of the present disclosure can be made from films having a thickness of about 100 to 400 microns, such as, extruded, cast or calendared films, which can be stretched at a ratio of 6.5:1 to 3:1 at a temperature of from the Tg of the film to the Tg + 55°C, and which can be stretched to a thickness of 20 to 80 microns. In one embodiment, the orientation of the initial as extruded film can be performed on a tenter frame according to these orientation conditions. [0089] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure have no more than 40% shrinkage in the transverse direction per 5°C temperature increase increment. [0090] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have an onset of shrinkage temperature of from about 55 to about 80°C, or about 55 to about 75°C, or 55 to about 70°C. Onset of shrinkage temperature is the temperature at which onset of shrinking occurs. [0091] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have an onset of shrinkage temperature of between 55°C and 70°C. [0092] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have a break strain percentage greater than 100% at a stretching speed of 300 mm/minute in the direction orthogonal to the main shrinkage direction according to ASTM Method D882. [0093] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have a break strain percentage of greater than 300% at a stretching speed of 300 mm/minute in the direction orthogonal to the main shrinkage direction according to ASTM Method D882. [0094] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have a tensile stress at break (break stress) of from 20 to 400 MPa; or 40 to 260 MPa; or 42 to 260 MPa as measured according to ASTM Method D882. [0095] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can have a shrink force of from 2 to 18 MPa, or from 4 to 15 MPa, as measured by ISO Method 14616 depending on the stretching conditions and the end-use application desired. For example, certain labels made for plastic bottles can have an MPa of from 4 to 8 and certain labels made for glass bottles can have a shrink force of from 10 to 14 MPa as measured by ISO Method 14616 using a Shrink Force Tester made by LabThink @ 80°C. [0096] In one embodiment of the present disclosure, the polyester compositions can be formed by reacting the monomers by known methods for making polyesters in what is typically referred to as reactor grade compositions. [0097] In one embodiment of the present disclosure, the polyester compositions of this disclosure can be formed by blending polyesters, such as polyethylene terephthalate (PET), glycol modified PET (PETG), glycol modified poly(cyclohexylene dimethylene terephthalate) (PCTG), poly(cyclohexylene dimethylene terephthalate) (PCT), acid modified poly(cyclohexylene dimethylene terephthalate) (PCTA), poly(butylene terephthalate) and/or diethylene glycol modified PET (EASTOBOND™ copolyester) to achieve the monomer ranges of these compositions. [0098] In certain embodiments, the polyester compositions and the polymer blend compositions can also contain from 0.01 to 25% by weight of the overall composition common additives such as colorants, toner(s), dyes, mold release agents, flame retardants, plasticizers, glass bubbles, nucleating agents, stabilizers, including but not limited to, UV stabilizers, thermal stabilizers and/or reaction products thereof, fillers, and impact modifiers. Examples of commercially available impact modifiers include, but are not limited to, ethylene/propylene terpolymers, functionalized polyolefins such as those containing methyl acrylate and/or glycidyl methacrylate, styrene-based block copolymeric impact modifiers, and various acrylic core/shell type impact modifiers. Residues of such additives are also contemplated as part of the polyester composition. [0099] Reinforcing materials can be added to the polyester compositions useful in this disclosure. The reinforcing materials may include, but are not limited to, carbon filaments, silicates, mica, clay, talc, titanium dioxide, Wollastonite, glass flakes, glass beads and fibers, and polymeric fibers and combinations thereof. In one embodiment, the reinforcing materials include glass, such as, fibrous glass filaments, mixtures of glass and talc, glass and mica, and glass and polymeric fibers. [00100] Molded articles can also be manufactured from any of the polyester compositions disclosed herein which may or may not consist of or contain shrink films and are included within the scope of the present disclosure. [00101] Generally, the multilayer shrink films according to the present disclosure may contain from 0.01 to 10 weight percent of the polyester plasticizer. In one embodiment, the multilayer shrink films can contain from 0.1 to 5 weight percent of the polyester plasticizer. Generally, the multilayer shrink films can contain from 90 to 99.99 weight percent of the copolyester. In certain embodiments, the multilayer shrink films can contain from 95 to 99.9 weight percent of the copolyester. [00102] In one embodiment, when having a pre-oriented thickness of about 100 to 400 microns followed by orientation on a tenter frame at from a ratio of 6.5:1 to 3:1 at a temperature of from Tg to Tg + 55°C to a thickness of from about 20 to about 80 microns, the multilayer shrink films of the present disclosure can have one or more of the following properties: (1) shrinkage in the main shrinkage direction or transverse direction in the amount of greater than 50% (or greater than 60%, or greater than 70%), and 10% or less (or from -5% to 4%) shrinkage in the machine direction when immersed in water at 95°C for 10 seconds; (2) an onset of shrinkage temperature of from about 55°C to about 70°C; (3) a break strain percentage of greater than 100% at stretching speeds of 300 mm/minute, or 200 to 600%, or 200 to 500%, or 226 to 449%, or 250 to 455% in the transverse direction or in the machine direction or in both directions according to ASTM Method D882; (4) no more than 40% shrinkage per each 5°C temperature increase increment; and/or (5) strain induced crystalline melting point greater than 200°C. Any combination of these properties or all of these properties can be present in the shrink films of this disclosure. The shrink films of the present disclosure can have a combination of two or more of the above described shrink film properties. The shrink films of the present disclosure can have a combination of three or more of the above described shrink film properties. The shrink films of the present disclosure can have a combination of four or more of the above described shrink film properties. In certain embodiments, properties (1) – (2) are present. In certain embodiments, properties (1) - (5) are present. In certain embodiments, properties (1) – (3) are present, etc. [00103] The shrinkage percentages herein are based on initial as-formed films having a thickness of about 20 to 80 microns that have been oriented at a ratio of from 6.5:1 to 3:1 at a temperature of Tg to Tg + 55°C on a tenter frame, for example, at a ratio of 5:1 at a temperature from 70°C to 85°C. In one embodiment, the shrinkage properties of the oriented films used to make the shrink films of this disclosure were not adjusted by annealing the films at a temperature higher than the temperature in which it was oriented. [00104] The shape of the films useful in making the oriented multilayer films or multilayer shrink films of the present disclosure is not restricted in any way. For example, it may be a flat film or a film that has been formed into a tube. In order to produce the multilayer shrink films useful in the present disclosure, the polyester is first formed into a flat film and then is “uniaxially stretched”, meaning the polyester film is oriented in one direction. The films could also be "biaxially oriented," meaning the polyester films are oriented in two different directions; for example, the films are stretched in both the machine direction and a direction different from the machine direction. Typically, but not always, the two directions are substantially perpendicular. For example, in one embodiment, the two directions are in the longitudinal or machine direction ("MD") of the film (the direction in which the film is produced on a film-making machine) and the transverse direction ("TD") of the film (the direction perpendicular to the MD of the film). Biaxially oriented films may be sequentially oriented, simultaneously oriented, or oriented by some combination of simultaneous and sequential stretching. [00105] The multilayer films may be oriented by any usual method, such as the roll stretching method, the long-gap stretching method, the tenter-stretching method, and the tubular stretching method. With use of any of these methods, it is possible to conduct biaxial stretching in succession, simultaneous biaxial stretching, uni-axial stretching, or a combination of these. With the biaxial stretching mentioned above, stretching in the machine direction and transverse direction may be done at the same time. Also, the stretching may be done first in one direction and then in the other direction to result in effective biaxial stretching. In one embodiment, stretching of the films is done by preliminarily heating the films 5ºC to 80ºC above their glass transition temperature (Tg). In one embodiment, the films can be preliminarily heated from 10ºC to 30ºC above their Tg. In one embodiment, the stretch rate is from 5 to 20 inches (12.7 to 50.8 cm) per second. Next, the multilayer films can be oriented, for example, in either the machine direction, the transverse direction, or both directions from 2 to 6 times the original measurements. The multilayer films can be oriented as a single film layer or can be coextruded with another polyester such as PET (polyethylene terephthalate) as a multilayer film and then oriented. [00106] In one embodiment, the present disclosure includes an article of manufacture or a shaped article comprising the multilayer shrink films of any of the multilayer shrink film embodiments of this disclosure. In another embodiment, the present disclosure includes an article of manufacture or a shaped article comprising the multilayer oriented films of any of the multilayer oriented film embodiments of this disclosure. [00107] In certain embodiments, the present disclosure includes but is not limited to multilayer shrink films applied to containers, plastic bottles, glass bottles, packaging, batteries, hot fill containers, and/or industrial articles or other applications. In one embodiment, the present disclosure includes but is not limited to oriented films applied to containers, packaging, plastic bottles, glass bottles, photo substrates such as paper, batteries, hot fill containers, and/or industrial articles or other applications. [00108] In certain embodiments of the present disclosure, the multilayer shrink films of this disclosure can be formed into a label or sleeve. The label or sleeve can then be applied to an article of manufacture, such as, the wall of a container, battery, or onto a sheet or film. [00109] The multilayer oriented films or multilayer shrink films of the present disclosure can be applied to shaped articles, such as, sheets, films, tubes, bottles and are commonly used in various packaging applications. For example, films and sheets produced from polymers such as polyolefins, polystyrene, poly(vinyl chloride), polyesters, polylactic acid (PLA) and the like are used frequently for the manufacture of shrink labels for plastic beverage or food containers. For example, the multilayer shrink films of the present disclosure can be used in many packaging applications where the multilayer shrink film applied to the shaped article exhibits properties, such as, good printability, high opacity, higher shrink force, good texture, and good stiffness. [00110] The combination of the improved shrink properties as well as the improved toughness should offer new commercial options, including but not limited to, multilayer shrink films applied to containers, plastic bottles, glass bottles, packaging, batteries, hot fill containers, and/or industrial articles or other applications. [00111] In one aspect of the present disclosure, the disclosed polyester compositions are useful as thermoformed and/or thermoformable film(s) or sheet(s). The present disclosure is also directed to articles of manufacture which incorporate the thermoformed film(s) and/or sheet(s) of this disclosure. In one embodiment, the polyesters compositions of the present disclosure are useful as films and sheets which are easily formed into shaped or molded articles. In one embodiment, the film(s) and/or sheet(s) of the present disclosure may be processed into molded articles or parts by thermoforming. The polyester compositions of the present disclosure may be used in a variety of molding and extrusion applications. [00112] In addition, in one embodiment, the polyester compositions and the polyester blend compositions useful in the thermoformed sheet(s) of this disclosure may also contain from 0.1 to 25% by weight of the overall composition common additives such as colorants, mold release agents, flame retardants, plasticizers, nucleating agents, stabilizers, including but not limited to, UV stabilizers, thermal stabilizers, fillers, and impact modifiers. [00113] In one embodiment, reinforcing materials may be included in the thermoformed film(s) or sheet(s) comprising the polyester compositions of this disclosure. For examples, suitable the reinforcing materials may include carbon filaments, silicates, mica, clay, talc, titanium dioxide, Wollastonite, glass flakes, glass beads and fibers, and polymeric fibers and combinations thereof. [00114] In one embodiment, the thermoformed films or sheets are multilayered films or sheets. In one embodiment at least one layer of the multilayer film or sheet is a foam or foamed polymer or polyester layer. [00115] One aspect of the present disclosure is a method of making molded or shaped parts and articles using thermoforming. Any thermoforming techniques or processes known to those skilled in the art may be used to produce the molded or shaped articles of this disclosure. [00116] In one embodiment, the thermoforming processes can be done in several ways, for example as taught in "Technology of Thermoforming"; Throne, James; Hanser Publishers; 1996; pp. 16-29, which is incorporated herein by reference. In some embodiments, it is a positive thermoforming process where gas or air pressure is applied to the softened sheet, the sheet is then stretched and drawn out like a bubble and a male mold is brought into the bubble from the inside. Then vacuum is applied to further draw and conform the part to the male mold surface. In this thermoforming process biaxial stretching/orientation is done primarily in one step when there is a gas or air pressure applied to the softened sheet. The molding step is then completed with the vacuum and male mold to freeze the orientation into the sheet for a good balance of physical and appearance properties. In other embodiments, it is a negative thermoforming process where a vacuum or a physical plug is applied to the heat softened sheet and stretches and draws the sheet to nearly the final part size, and then, positive air pressure from the inside or further external vacuum from the outside draws and conforms the sheet against an outer, female mold, the orientation is frozen into the polymer and the sheet is formed into the article. [00117] In some embodiments, the produced bubble is sometimes further formed by making use of a plug assist, and this is followed by draping and shaping the sheet over the rising positive mold and then the corners and shelves guides, etc. are pulled into the mold by applying a vacuum. In some embodiments, after removal from the mold, the molded parts or articles can be trimmed, holes punched, and corners cut out as needed. [00118] In other embodiments, thermoforming is a process where a film or sheet of the polyester compositions of the present disclosure are heated to a temperature sufficient to allow the deformation thereof, and the heated film or sheet is then made to conform to the contours of a mold by such means as vacuum assist, air pressure assist and matched mold assist. In another embodiment, the heated film or sheet is placed in a mold and forced to conform to the contours of the mold by, for example, application of air pressure, application of a vacuum, plug assist or application of a matching mold. In some embodiments, thermoforming produces thin wall articles. [00119] In one embodiment, the thermoforming process molds the films or sheets into the desired shapes through the pressing of positive molds into the heated films or sheets. In this embodiment, thermoforming involves having a positive mold of an article supported between a vacuum-equipped surface or table. In this embodiment, heat from an external heat source such as a hot air blower, heat lamp or other radiant heat source is directed at the film or sheet. In this embodiment, the film or sheet is heated to the point of softening. In this embodiment, a vacuum is then applied to and below the table and around the mold, and the heat softened film or sheet is drawn toward the table, thus placing the softened film or sheet in contact with the mold surface. In this embodiment, the vacuum draws the softened film or sheet into tight contact with, and conformance to, the contours of the mold surface. As such, the film or sheet then assumes the shape of the mold. In this embodiment, after the film or sheet cools, it hardens, and the resulting article or part may be removed from the mold. [00120] In one embodiment, the thermoforming process comprises: forming a film or sheet from the polyester compositions of the present disclosure; heating the film or sheet until it softens and positioning it over a mold; drawing the preheated film or sheet onto the heated mold surface; cooling the film or sheet; and then removing the molded article or part from the mold cavity, or optionally, heatsetting the formed film or sheet by maintaining the film or sheet in contact against the heated mold for a sufficient time period to partially crystallize the film or sheet. [00121] In one embodiment, the thermoforming process comprising: forming a film or sheet from the polyester compositions of the present disclosure; heating a film or sheet to a temperature at or above the Tg of the polyester; applying gas, vacuum and/or physical pressure to the heat softened film or sheet and stretching the film or sheet to nearly the final part size; conforming the sheet by vacuum or pressure to a mold shape; cooling the film or sheet to a temperature below the Tg of the polyester; and then removing the thermoformed article or part from the mold. [00122] The film and sheet used in the thermoforming process can be made by any conventional method known to those skilled in the art. In one embodiment, the sheet or film is formed by extrusion. In one embodiment, the sheet or film is formed by calendering. In one embodiment, during the thermoforming process the film or sheet is heated to a temperature at or above the Tg of the polyester. In one embodiment, this temperature is about 10 to about 60° C above the Tg of the polyester. In one embodiment, the heating of the film or sheet prior to positioning over the thermoforming mold is necessary in order to achieve a shorter molding time. In one embodiment, the sheet must be heated above its Tg and below the point at which it sags excessively during positioning over the mold cavity. In one embodiment, before the molded film or sheet is removed from the mold it is allowed to cool to a temperature below the Tg of the polyester. In one embodiment, the thermoforming methods may include vacuum assist, air assist, mechanical plug assist or matched mold. In some embodiments, the mold is heated to a temperature at or above the Tg of the film or sheet. Selection of optimum mold temperature is dependent upon type of thermoforming equipment, configuration and wall thickness of article being molded and other factors. [00123] In some embodiments, the heated film or sheet is stretched by creating and pulling a vacuum. [00124] In one embodiment, heatsetting is the process of thermally inducing partial crystallization of a polyester film or sheet without appreciable orientation being present. In one embodiment, heatsetting is achieved by maintaining contact of the film or sheet with the heated mold surface for a sufficient time to achieve a level of crystallinity which gives adequate physical properties to the finished part. In one embodiment, the levels of crystallinity should be about 10 to about 30 percent. [00125] In one embodiment, the heatset part can be removed from the mold cavity by known means for removal. For example, in one embodiment, blowback is used and it involves breaking the vacuum established between the mold and the formed film or sheet by the introduction of compressed air. In some embodiments, the molded article or part is subsequently trimmed and the scrap ground and recycled. [00126] In some embodiments, the addition of nucleating agents provide faster crystallization during thermoforming and thus provide for faster molding. In one embodiment, nucleating agents such as fine particle size inorganic or organic materials may be used. For example, in one embodiment, suitable nucleating agents include talc, titanium dioxide, calcium carbonate, and immiscible or cross-linked polymers. In one embodiment, the nucleating agents are used in amounts varying from about 0.01% to about 20%, based on the weight of the article. In one embodiment, other conventional additives such as pigments, dyes, plasticizers, anti-cracking agent and stabilizers may be used as needed for thermoforming. In some embodiments, the anti-cracking agent improves impact strength, and the nucleating agent provides faster crystallization. In some embodiments, crystallization is necessary to achieve high temperature stability. [00127] In one embodiment, a foamed polyester film or sheet is made by foaming a polyester composition of the present disclosure with chemical and/or physical blow agents, extruding the foamed polyester into sheet or film, and thermoforming the foamed polyester film or sheet. Additives for providing enhanced properties to the foamed polyester film may be added to the polyester prior to foaming. Some examples of additives include slip agents, antiblocking agents, plasticizers, optical brightener and ultra violet inhibitor. In one embodiment, the foamed polyester films can be extrusion or lamination coated on one side or on both sides using conventional techniques in order to enhance its properties. In one embodiment, the coating materials may be the printed surface, rather than the foam film itself, that provides for product labelling.

[00140] General multilayer film making process and property test description [00141] The multilayer heat-shrinkable polyester films in the Examples were prepared and evaluated by a method comprising the steps of: (a) melting and extruding the random copolymer resin with certain layer structure to obtain an unstretched A|B|A trilayer film; (b) stretching the unstretched multilayer film in the one direction; (c) evaluating various film properties (including glass transition temperature (Tg), strain-induced melting point (Tm), shrinkage as a function of temperature (shrink curve), tensile test and shrink force (SF)) and (d) evaluating film recyclability through clump testing.

[00152] The desired performance for shrink film made with this multilayer structure includes (a) The ultimate shrinkage in the main shrinkage direction (transverse direction, TD) of at least have 50%, preferred 70% or greater, which increases gradually with increasing temperature; (b) The shrinkage in the direction orthogonal to the main shrinkage direction at 80 °C should be negative (i.e., growth) or no shrinkage; (c) The final shrinkage films should also possess a shrink force less than 10 MPa measure at 80 °C; (d) A break strain percentage of greater than 100% at a stretching speed of 300 mm/min in machine direction (MD, direction orthogonal to the main shrinkage direction) [00153] Film recyclability. Shrunk film heated together with rPET flake with 3 wt% of shrunk film at 208 °C for 90 mins showing < 5% clumping, more preferred < 1% clumping measured by clump test described in experimental section. [00154] Film preferably has an inherent viscosity (I.V.) of 0.5-0.9 dL/g, more preferred of 0.55 – 0.7 dL/g for good film physical property and film processability.

Stretching the unstretched film using the Bruckner Karo machine in one direction at 70 °C – 100 °C by about 3-6 times the original dimensions, more preferred from stretch at 70 °C – 90 °C by about 3-5 times. The thickness of the heat-shrinkable polyester film prepared in accordance with the present invention may be 20 µm to 80 µm, preferably 30 µm to 50 µm. The stretched film was evaluated for various film properties, including glass transition temperature (Tg), strain-induced melting point (Tm), shrinkage as a function of temperature (shrink curve), tensile test and shrink force (SF)) and (e) evaluating film recyclability through clump testing. Analytical Test [00156] Inherent viscosity (I.V.) - IV was measured in a 60/40 parts by weight solution of phenol/tetrachloroethane at 250°C and at a concentration of about 0.5 g of polymer in 100 mL of said solvent. [00157] Film glass transition temperature (Tg) and melting temperature (Tm) All thermal tests for these pellets and stretched film were completed at standard differential scanning calorimetry (DSC) scans at a scan rate of 20 °C/min. [00158] Shrink force (SF) - Shrink force was determined using a Labthink FST-02 shrink force tester. Shrink force measurements were conducted under the same temperature conditions as the stretching temperatures used to stretch films on the Bruckner (80 °C) and held in the heating chamber for 60 seconds— to ascertain the maximum shrink force value of each film. [00159] Shrinkage - Shrinkage was measured by placing a 50mm by 50mm square film sample in water at temperatures ranging from 60 °C to 95 °C for 10 seconds without restricting shrinkage in any direction. The percent shrinkage was then calculated using the following equation: % shrinkage = [(50mm-length after shrinkage)/50mm]x100% • Shrinkage was measured in the direction orthogonal to the main shrinkage direction (machine direction, MD) and was also measured in the main shrinkage direction (transverse direction, TD). • Negative shrinkage indicated growth [00160] Tensile property - The film was tested for MD break strain using ASTM Method D882. The film was prepared by cutting them to 3.5” x 0.5” strips and tested at a stretching speed of 300 mm/min. [00161] PET Clumping - A clump test of these compositions was performed by first shrinking the stretched films at 85°C for 10 seconds and shredding the shrunken material to create shrink flake. 18 grams of shrink flake was then combined with 582 grams of PET flake and spread evenly into an aluminum cooking pan, ensuring a depth of 1.5” of material. The pan was placed in a forced air oven set to 208°C for 90 minutes and allowed to cool before being evaluated for clumping percentage using the formula below. [ (Weight of remaining material + pan) - (weight of pan) / (600 g)] x 100 = degree of clumping (%) Comparative Examples [00162] NOTE: Comments for shrink film performance in tables below [00163] GOOD: The desired performance for shrink film made with this multilayer structure includes • The ultimate shrinkage in the main shrinkage direction (transverse direction, TD) of at least has 50%, preferred 70% or greater, which increases gradually with increasing temperature. • The shrinkage in the main shrinkage direction at 70°C at least has 5%. • The shrinkage in the direction orthogonal to the main shrinkage direction at 80°C should be negative (i.e., growth) or no shrinkage; • The final shrinkage films should also possess a shrink force less than 10 MPa measure at 80°C; • A break strain percentage of greater than 100% at a stretching speed of 300 mm/min in machine direction (MD, direction orthogonal to the main shrinkage direction) • The shrunk film dried together with PET flake at oven at 208°C for 90 mins shown < 1% clumping. [00164] NOT IDEAL: Shrink film performance didn’t meet the criteria described for “good” Comparative examples [00165] The composition and film properties of comparative examples are shown in the table 3 below.
