Methods and Systems for Its Manufacture

BACKGROUND

Technical Field

[0001] In various embodiments, the present invention relates to an improved resealable package, an improved precursor for the resealable package, and an assembly comprising the package along with a product inside the package. Furthermore, the invention relates to packages with a reseal region configured to provide the package with resealability. For example, the reseal region can be located inside a primary seal region and adj acent to a product. As a portion of the product is consumed, a portion of the reseal region is exposed, and the exposed portion of the reseal region can be adhered to itself using a cold seal adhesive, thereby providing the package with resealability.

Background

[0002] The inventor has recognized that many existing packages for products fail to include a closure for resealing the package. If a consumer does not completely consume the product in a single sitting, the remaining product can deteriorate in terms of freshness, organoleptic properties, or other desirable characteristics.

[0003] Furthermore, while some existing packages do include the ability to reseal, for example, using zippers or other conventional closures, the inventor realized that these closures can be expensive. For example, the closures themselves add costs to packaging materials, and the process required to add the closures can require retrofitting packaging lines by adding new equipment and modifying existing equipment. These modifications require time, maintenance staff, and can significantly impede use of a production line and interrupt production schedules.

[0004] Advantageously, the inventor has discovered improved packaging materials and related processes that, at least in some embodiments, can mitigate or eliminate one or more of the previously mentioned problems. These and additional advantages associated with various embodiments of the improved packaging materials and related processes will be further evident to a person having ordinary skill in the art upon reviewing the present disclosure.

DETAILED DESCRIPTION

[0031] Among other discoveries, as disclosed herein, the inventor has discovered that a packaging precursor, for example, a wrapper for an existing product, can be coated with a cold seal adhesive to provide a reseal region of the wrapper and resealability for a package made using the wrapper. If the coated region is an interior region of the wrapper or another region that does not overlap the primary seal regions of the wrapper, interference with the primary seals can be avoided. For example, if cold seal adhesive is deposited on an interior region of a wrapper, and the edge regions of the wrapper are not coated with the cold seal adhesive, heat seal jaws or a primary adhesive can be used to form primary seals along the edges of the wrapper, and the sealing and barrier properties of these primary seals can be generally maintained as though no cold seal adhesive were applied to the wrapper.

[0032] In developing various embodiments of improved packaging materials and processes for making these packaging materials, the inventor realized several potential advantages for the improved materials, systems and/or processes described herein. For example, as compared to packages without resealability, the improved packages can help to maintain the freshness, organoleptic properties, or other desirable characteristics of a product contained within the package.

[0033] Additionally, as compared to packages that use conventional means for resealing, for example, zippers, the improved packages can be made less expensively. For example, with respect to material costs, the cost of the cold seal adhesive can be significantly less expensive than the cost of an added closure such as a zipper. Similarly, the cost of equipment for coating a wrapper with cold seal adhesive can be significantly less expensive than equipment for incorporating an added closure, such as a zipper, into a wrapper or package.

[0034] Moreover, the improved packages can be made using existing equipment, such as existing form, fill, and seal machines. For example, in some embodiments, an improved package precursor, comprising a wrapper and cold seal adhesive, can be fed to a form, fill and seal machine in a manner that is similar or identical to the way that a package precursor without the cold seal adhesive would be fed to the form, fill and seal machine. Furthermore, the cold seal adhesive can be deposited on the wrapper using existing printing or deposition equipment for depositing adhesive, ink, pigment, other materials, or a combination thereof on the wrapper. Accordingly, in conjunction with some embodiments of the improved packaging materials, a product packaging line for a non-resealable package can be quickly and inexpensively converted into a product packaging line for a resealable package.

[0035] With reference now to Figure 1 and Figure 2, an embodiment of an improved package precursor 0100 for an improved resealable package 0200, will now be described. As illustrated, the precursor 0100 comprises: a wrapper 0102, at least one primary seal region 0104 of the wrapper 0102, and a reseal region 0106 of the wrapper 0102.

[0036] Turning first to the wrapper of the precursor, the wrapper 0102 can comprise a first end 0116, a second end 01 18, a first edge 0120, a second edge 0122 or a combination thereof. In the illustrated embodiment, the second end 0118 is opposite the first end 0116, and the second edge 0122 is opposite the first edge 0120. Additionally, (i) the first end 0116 of the wrapper can be adjacent to the first edge 0120, the second edge 0122 or both the first edge 0120 and the second edge 0122 of the wrapper; (ii) the second end 0118 of the wrapper can be adjacent to the first edge 0120, the second edge 0122 or both the first edge 0120 and the second edge 0122 of the wrapper; (iii) the first edge 0120 of the wrapper can be adjacent to the first end 01 16, the second end 01 18 or both the first end 01 16 and the second end 0118 of the wrapper; and (iv) the second edge 0122 of the wrapper can be adjacent to the first end 01 16, the second end 01 18 or both the first end 01 16 and the second end 0118 of the wrapper.

[0037] In some embodiments, the first end 01 16 is separated from the second end 0118 by a minimum length 0132 of the wrapper 0102. In some embodiments, the first edge 0120 is separated from the second edge 0122 by a minimum width 0134 of the wrapper 0102. Additionally, because a wrapper can have an irregular shape, it can be useful to provide generalized definitions of length and width to facilitate determining the dimensions of irregularly shaped wrappers. Accordingly, as illustrated with reference to Figure 12, a length reference line 1200 for the wrapper 0102 can be defined as a line from any first end point 1202 on the first end 01 16 of the wrapper 0102 to any second end point 1204 on the second end 01 18 wrapper 0102. Furthermore, a minimum length reference line 1206 can be defined as the length reference line 1200 with the shortest length. Then, using these definitions, a minimum length 1208 of the wrapper 0102 can be defined as the length of the minimum length reference line 1206.

[0038] In some embodiments, the minimum length 1208 of the wrapper 0102 is at least 15, 20, 25, 26, 27, 28, 29 or 30 cm; no more than 15, 20, 25, 26, 27, 28, 29 or 30 cm; or a combination thereof. In some embodiments, the maximum length of the wrapper is at least 30, 31 , 32, 33, 34, 35, 40 or 60 cm; no more than 30, 31 , 32, 33, 34, 35, 40 or 60 cm; or a combination thereof. In some embodiments, a maximum length 1210 of the product containment region 01 14 in a direction parallel to the minimum length reference line 1206 is at least 1, 2, 3, 4, 5, 10, 15, 20, 25, 26, 27, 28, 29, or 29.5 cm; no more than 1 , 2, 3, 4, 5, 10, 15, 20, 25, 26, 27, 28, 29, or 29.5 cm; or a combination thereof. In some embodiments, a minimum length 1212 of the product containment region 01 14 in a direction parallel to the minimum length reference line 1206 is at least 1, 2, 3, 4, 5, 10, 15, 20, 25, 26, 27, 28, 29, or 29.5 cm; no more than 1, 2, 3, 4, 5, 10, 15, 20, 25, 26, 27, 28, 29, or 29.5 cm; or a combination thereof.

[0039] With reference to Figure 13, a width reference line 1300 can be defined as a line that is perpendicular to the minimum length reference line 1206 and extends from any first edge point 1302 on the first edge 0120 of the wrapper 0102 to any second edge point 1304 on the second edge 0122 of the wrapper 0102.

[0040] As can be seen with reference to Figure 13, a width 1306 of the wrapper 0102 at any reference point 1308 along the minimum length reference line 1206 can be measured from the first edge 0120 of the wrapper 0102 to the second edge 0122 of the wrapper 0102 and along the width reference line 1300 passing through the reference point 1308.

[0041] With reference to these definitions, it can be useful to define a minimum width reference line 1310 as the width reference line 1300 with the shortest width. Similarly, it can be useful to define a minimum width 1312 of the wrapper 0102 as the width of the minimum width reference line 1310. In some embodiments, the minimum width 1312 of the wrapper 0102 is at least 10, 15, 16, 17, 18, 19 or 20 cm; no more than 10, 15, 16, 17, 18, 19 or 20; or a combination thereof. In some embodiments, a maximum width 1314 of the product containment region 01 14 in a direction parallel to the minimum width reference line 1310 is at least 1, 2, 3, 4, 5, 10, 1 1, 12, 13, 14, 15, 16, 17, 18, 19, or 19.5 cm; no more than 1 , 2, 3, 4, 5, 10, 11 , 12, 13, 14, 15, 16, 17, 18, 19, or 19.5 cm; or a combination thereof. Furthermore, in some embodiments, a minimum width 1316 of the product containment region 01 14 in a direction parallel to the minimum width reference line 1310 is at least 1, 2, 3, 4, 5, 10, 11 , 12, 13, 14, 15, 16, 17, 18, 19, or 19.5 cm, no more than 1 , 2, 3, 4, 5, 10, 1 1, 12, 13, 14, 15, 16, 17, 18, 19, or 19.5 cm, or a combination thereof.

[0042] As a person having ordinary skill in the art would understand after reading the present disclosure, the wrapper can be made using any appropriate materials. As an example, in some embodiments, the wrapper 0102 comprises film, polymer, plastic, thermoplastic, metal, paper, or a combination thereof. Additionally, the wrapper can be provided with desirable structural characteristics, as the skilled person would also understand after reading the present disclosure. For example, in some embodiments, the wrapper 0102 can comprise at least one element selected from the following group of elements: bi-oriented film, polypropylene film, clear film, metallized film, aluminum- metallized film, at least two layers, 10-20 gauge film, 15 gauge film, or a combination thereof. [0043] With reference to Figure 10, in some embodiments, the wrapper 0102 can be made from one or more layers or deposits. For example, the wrapper 0102 can comprise layers and/or deposits selected from the group consisting of: a primary layer 1000, an ink deposit 1002 (e.g., comprising any ink deposited on the primary layer 1000, which primary layer 1000 can be clear), an adhesive deposit 1004, a barrier layer 1006, a print layer, a product 0206 facing layer (e.g., the barrier layer 1006), and a combination thereof. Additionally, the wrapper 0102 can comprise a plurality of layers and deposits arranged in the following order: a primary layer 1000, an ink deposit 1002, an adhesive deposit 1004, and a barrier layer 1006.

[0044] With reference to Figure 10, the barrier layer 1006 can be adhered (directly or indirectly) to the primary film layer 1000. In some embodiments, at least one ink deposit 1002, at least one color deposit 1002, at least one adhesive deposit 1004, at least one non-film layer, or a combination thereof are positioned between the primary film layer 1000 and barrier layer 1006.

[0045] The primary film layer 100 can comprise bi-axially oriented polypropylene, be clear, be reverse printed, or a combination thereof. Additionally, the primary film layer 1000 is configured to form a portion of the wrapper 0102 that is separated from the product 0206 by the barrier layer 1006. In some embodiments, the primary film layer 1000 is configured to be a print layer. Optionally, the print layer (e.g., including any decoration, message, information, etc.) is configured to form a portion of the wrapper 0102 that is visible from an exterior of the wrapper 0102. Moreover, the primary film layer 1000 can be reverse printed on the surface of the primary film layer 1000 that is adj acent to the barrier layer 1006, or a combination thereof. In some embodiments, the primary film layer can have a thickness of 10-20 gauge (e.g. 15 gauge) or can have a thickness of 10-30 micron, 10-20 micron (e.g. 15 micron), or 20-30 micron (e.g., 25 micron).

[0046] The barrier layer 1006 can comprise bi-axially oriented polypropylene, be clear, be metallized (e.g., with aluminum) or a combination thereof. The barrier layer 1006 can comprise a barrier film layer 1008, a metal layer 1010, a metallized barrier film layer 1012, or a combination thereof. Optionally, the barrier layer 1006, barrier film layer 1008, metal layer 1010, or metallized barrier film layer is configured to be on a product-facing surface 0204 of the wrapper 0102 that is adjacent to the product 0206. In some embodiments, the barrier film layer 1008 has a thickness of 10-20 gauge (e.g., 15 gauge) or a thickness of 10-20 micron (e.g., 15 micron).

[0047] Turning next to the at least one primary seal region 0104 of the wrapper, it can comprise: a first end seal region 0124, a second end seal region 0126, a first longitudinal seal region 0128, a second longitudinal seal region 0130, or a combination thereof. As illustrated, the first end seal region 0124 is configured (e.g., positioned, oriented, made of materials, designed, or a combination thereof) to provide a first end seal 0214 for the package 0200. The first end seal region 0124 of the wrapper is adjacent to a first end 01 16 of the wrapper. Similarly, the second end seal region 0126 is configured to provide a second end seal 0216 for the package 0200, and the second end seal region 0126 of the wrapper is adj acent to the second end 01 18 of the wrapper.

[0048] If a package is made, for example, from a wrapper that forms a closed surface or closed loop in at least one direction (e.g., a cylinder), then the package can be made using only end seals. However, when a package is made from a flat wrapper that does not form a closed surface or closed loop, as illustrated in Figure 1, it can be useful for the package to include longitudinal seals, to provide the structural effect of a wrapper with a closed surface or closed loop.

[0049] Accordingly, as illustrated in Figure 1, a wrapper 0102 can comprise a first longitudinal seal region 0128 and a second longitudinal seal region 0130. As illustrated, the first longitudinal seal region 0128 is adjacent to the first edge 0120, and the second longitudinal seal region 0130 is adjacent to the second edge 0122. Furthermore, with reference to Figure 1 and Figure 2, the first longitudinal seal region 0128 and the second longitudinal seal region 0130 are configured (e.g., positioned, oriented, made of materials, designed, or a combination thereof) to provide a longitudinal seal 0900 (e.g., lap seal, fin seal, etc.) for a package 0200.

[0050] In some embodiments, the at least one primary seal region 0104 of the wrapper 0102 (e.g., first end seal region 0124, second end seal region 0126, first longitudinal seal region 0128, second longitudinal seal region 0130, or a combination thereof) can be sealed using energy (e.g., using heat, seal jaws, pressure, electromagnetic energy, ultrasonic waves, radiation, infrared radiation, light, or a combination thereof) to melt the wrapper 0102 in the at least one primary seal region 0104 so that the at least one primary seal region 0104 sticks to itself or a corresponding seal region (e.g., another seal region described herein) to form at least one primary seal 0210. Accordingly, in some embodiments, the at least one primary seal region 0104 of the wrapper 0102 comprises or is a thermoplastic.

[0051] Additionally, in some embodiments, the at least one primary seal region 0104 of the wrapper 0102 (e.g., first end seal region 0124, second end seal region 0126, first longitudinal seal region 0128, second longitudinal seal region 0130, or a combination thereof) can be sealed using an adhesive coating on the at least one primary seal region 0104 so that the at least one primary seal region 0104 sticks to itself or a corresponding seal region (e.g., another seal region described herein) to form at least one primary seal 0210.

[0052] In some embodiments, an adhesive used in the at least one primary seal region 0104 (e.g., the first end seal region 0124, second end seal region 0126, first longitudinal seal region 0128, second longitudinal seal region 0130, or a combination thereof) is selected from the group consisting of: cold seal adhesive, non-resealable adhesive, permanent adhesive and a combination thereof.

[0053] As illustrated in the embodiments of Figure 1 and Figure 2, the wrapper 0102 comprises a product containment region 0114, which is configured to provide a product containment surface 0202 of the package 0200. In turn, the product containment surface 0202 and the at least one primary seal region 0104 of the wrapper are configured to provide a boundary for a product containment space 0212 within the package 0200. Additionally, at least one primary seal 0210 of the package 0200 comprises the at least one primary seal region 0104 of a wrapper 0102.

[0054] After the primary seal is opened by a consumer, the primary seal can lose its ability to provide a closure for the package. Accordingly, the at least one reseal region 0106 of the wrapper 0102 is configured to provide resealability for the package 0200 after opening the at least one primary seal 0210.

[0055] As illustrated in Figure 1 and Figure 2, the reseal region 0106 is configured to form at least a portion (e.g., at least 5, 10, 15, 20, 25, 30, 35, 40, 35, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or 100%) of a product containment surface 0202 and/or product-facing surface 0204 of the package 0200. Furthermore, in the illustrated embodiment, the product-facing surface 0204 of the package 0200 is located within a boundary formed by the at least one primary seal region 0104 (e.g. the first end seal region 0124, the second end seal region 0126, the first longitudinal seal region 0128, the second longitudinal seal region 0130, or a combination thereof).

[0056] Turning now to the reseal region of the wrapper, the reseal region 0106 is configured to adhere to itself when pressed against itself (e.g., by folding, twisting, etc.), for example, as a result of an adhesive that is deposited on the reseal region of the wrapper. If the adhesive is of a kind that adheres to surfaces in general, it is sufficient to coat only one of two reseal portions that are configured to be mutually adhered. While this can be acceptable in some packaging embodiments, it can create issues with respect to undesired adhesion. For example, if a surface that is coated with adhesive is adjacent to a product, then the coated surface could adhere unintentionally to the product. [0057] In contrast, the use of a cold seal adhesive can reduce or completely avoid unintentional adhesion. For example, when a cold seal adhesive is deposited on a portion of the reseal region, adherence to surfaces that are not coated with the cold seal adhesive can be avoided. Meanwhile, by coating two portions of the reseal region with cold seal adhesive and then pressing the two portions together, the two portions can be adhered to each other. Accordingly, it can be advantageous to use a cold seal adhesive, as opposed to other types of adhesive, to provide adherence between different portions of the reseal region.

[0058] As an example, Figure 1 illustrates a reseal region comprising a cold-seal-adhesive- coated region 0108. Cold seal adhesive 0110 is deposited on the cold-seal-adhesive-coated region 0108 of the wrapper 0102. Accordingly, the cold-seal-adhesive coated region 0108 can be pressed against itself to form a reseal closure. Optionally the cold-seal-adhesive- coated region 0108 is co-extensive with the reseal region. For example, the reseal region can be the cold-seal-adhesive-coated region. Furthermore, in some embodiments, the cold-seal- adhesive-coated region 0108 of the wrapper 0102 is configured to provide the product-facing surface 0204 of the package 0200, an inner surface of the package 0200, or a combination thereof. As explained herein, using a cold seal adhesive on a product-facing surface or inner surface of a package can be advantageous because the cold seal adhesive can be configured to avoid adhesion to the product.

[0059] In some embodiments, a cold seal adhesive 01 10 applied to the cold-seal-adhesive- coated region 0108 is a water-based emulsion. In some embodiments, a cold seal adhesive 01 10 is applied to the cold-seal-adhesive-coated region 0108 in a cold seal adhesive layer 1100 having a thickness 1102 equal to 1-5, 1-4, 2.5-3.5 or about 3 microns.

[0060] Additionally, upon reading the present disclosure, a skilled person would understand that various embodiments of a wrapper with different shapes and configurations can be used to provide a primary seal region and a reseal region for an improved resealable package. As an example, in some embodiments, the wrapper 0102 is shaped like a rectangle (e.g., square). Similarly, in some embodiments, the first end seal region 0124, second end seal region 0126, first longitudinal seal region 0128, second longitudinal seal region 0130, reseal region 0106, cold-seal-adhesive-coated region 0108, product-facing surface 0204, product containment surface 0202, or a combination thereof is shaped like a rectangle (e.g., square).

[0061] With reference now to Figure 4, in some embodiments, a precursor 0100 is configured to provide a roll 0400 of the wrapper 0102. Optionally, the roll 0400 comprises a plurality of precursors 0100, a plurality of the at least one primary seal regions 0104, a plurality of the reseal regions 0106, or a combination thereof. [0062] With reference to Figure 5 and Figure 6, the precursor 0100 can be configured to be fed with the product 0206 (e.g. a plurality of product units 0208) to a form, fill and seal machine 0600 and the form, fill and seal machine 0600 forms the precursor 0100 into at least one package 0200 that contains the product 0206. As an example, the form, fill and seal machine 0600 can form the precursor into a plurality of packages 0200, and each package 0200 can comprise at least one of the product units 0208 or a plurality of the product units 0208.

[0063] With reference again to Figure 1 and Figure 2, the at least one primary seal region 0104 of the wrapper 0102 is configured to form at least one primary seal 0210 (e.g., a heat seal, ultrasonic weld, permanent seal, adhesive bond, non-resealable seal or combination thereof) for the package 0200. In some embodiments, the at least one primary seal 0210 does not comprise cold seal adhesive 0110. This can be useful, for example, when the cold seal adhesive could interfere with formation of the primary seal.

[0064] With reference to Figure 1 , Figure 2, and Figure 7, the reseal region 0106 is configured to form a reseal closure 0700 by adhering a first portion 0702 of the reseal region 0106 to a second portion 0704 of the reseal region 0106. In some embodiments, the cold seal adhesive 0110 provides a reseal closure 0700 that has a maximum seal strength of at least 0.56, 1.1 , 2.2, 3.3, 4.4, 8.9, 13, 17, or 22 N / 15 mm seal width (0.125, 0.25, 0.5, 0.75, 1, 2, 3, 4 or 5 lb-f / in. seal width), no more than 0.56, 1.1 , 2.2, 3.3, 4.4, 8.9, 13, 17, or 22 N / 15 mm seal width (0.125, 0.25, 0.5, 0.75, 1, 2, 3, 4 or 5 lb-f / in. seal width), or a combination thereof. This maximum seal strength value can be the value associated with a continuous cold seal adhesive layer adhered to another continuous cold seal adhesive layer. Alternatively, it can be the maximum seal strength provided when a first cold seal layer with a corresponding first configuration as applied to the wrapper is pressed against a second cold seal layer with a corresponding second configuration as applied to the wrapper, noting that the first and second configuration can be the same or different. A higher maximum seal strength can be useful, for example, to prevent a reseal closure from opening unintentionally. The seal strength can be measured by providing a discrete portion of the wrapper comprising two sheets of the wrapper that are each coated with cold seal adhesive and that are pressed together between two flat plates using 5 psi at 25 °C for 0.5 seconds to provide the seal while leaving an unsealed portion of each sheet, thereby providing a single interface that extends along the sealed and unsealed portions of both of the two sheets. The interface between the sealed and unsealed portions is 15 mm wide, thereby providing the 15 mm seal width. To determine the maximum seal strength, one of the unsealed portions of the wrapper is pulled in a direction opposite the other unsealed portion of the wrapper while the seal between the two sheets is supported (e.g., by hand) at 90 degrees to the pull direction, thereby causing a seal failure along the 15 mm seal width. While the unsealed portion of the wrapper is pulled, the pull force is measured and the maximum force measured is the maximum seal strength.

[0065] With reference to Figure 1 and Figure 2, in some embodiments, the wrapper 0102 is configured to form a package 0200 for the product 0206 with specified barrier properties that are sufficient to satisfy a product quality test. The product 0206 quality test comprises providing the product 0206 in the package 0200 with at least one initial product characteristic at an initial time, and storing the package 0200 in air at 40 °C and 80% relative humidity from the initial time to a final time that occurs 8 weeks after the initial time. Then, at least one final characteristic of the product 0206 is measured at the final time.

[0066] In conducting the product quality test, the at least one initial characteristic is selected from the group consisting of: a moisture content equal to 2.18 wt. % +/- 10, 5, 4, 3, 2, 1 , or 0%, a water activity equal to 0.17 +/- 10, 5, 4, 3, 2, 1, or 0%, a force required to break the product 0206 equal to 3.00 kg-force +/- 10, 5, 4, 3, 2, 1, or 0% (e.g., as measured using a texturometer), a color intensity of 3.91 +/- 10, 5, 4, 3, 2, 1 , or 0% wherein the color intensity is equal to the L coordinate of the color of the product in the CIEL*a*b* 1976 color space as measured using a colorimeter, and a combination thereof. Accordingly, the at least one final characteristic is selected from the group consisting of: a moisture concentration equal to no more than 4.0, 3.5, 3.0, or 2.84 wt. %, a water activity equal to no more than 0.40, 0.35, 0.30, or 0.25, a force required to break the product 0206 equal to at least 2.40, 2.50, 2.60 or 2.70 kg-force (e.g., as measured using a texturometer), a color intensity of 4.06% +/- 10, 5, 4, 3, 2, 1, or 0% wherein the color intensity is equal to the L coordinate of the color of the product in the CIEL*a*b* 1976 color space as measured using a colorimeter, and a combination thereof.

[0067] In some embodiments, the wrapper 0102 is configured to form a package 0200 for the product 0206 with specified barrier properties that are sufficient to satisfy a product quality test. The product quality test comprises providing the product 0206 in the package 0200 and storing the package 0200 for 10 weeks in air at 40 °C and 80% relative humidity. The product 0206 quality test is satisfied if the product 0206: has a total count of colony forming units per gram (CFU/g) that is less than 5,000, 4,000, 3000, 2000, 1000, 500, 400, 300, 200, 100, 50, 40, or no more than 30 CFU/g as measured per PEM-008, has a total coliforms count that is less than 20, 15, 14, 13, 12, 1 1, or 10 CFU/g as measured per method PEM-010, has a mold count that is less than 100, 90, 80, 70, 60, 50, 40, 30, 20 or no more than 10 CFU/g as measured per PEM-009, has a yeast count that is less than 100, 90, 80, 70, 60, 50, 40, 30, 20 or 10 CFU/g as measured per PEM-009, tests negative for salmonella in 10 grams of the product 0206 per PEM-016, tests negative for Escherichia Coli in 10 grams of the product 0206 per PEM-028, or a combination thereof.

[0068] With reference to Figure 18, Figure 19, Figure 20, Figure 21, Figure 22, Figure 23 and Figure 24, in some embodiments the product (i.e., Gamesa Marias brand cookies) is stored in the package in air at 40 °C and 80% relative humidity for a specified time (i.e. "Storage Time") illustrated in Figures 18-24. The product being stored in the improved resealable package whose barrier properties are being tested is labeled with a "T" in Figures 18-24. Upon storage for the specified time, the product is removed from storage and removed from the improved resealable package and various sensed characteristics (e.g., organoleptic properties) listed in Figures 18-24 are measured using a taste testing panel of 10 trained panelists rating a sample of the product in duplicate for each evaluated sensed characteristic on a scale of 0 to 15, with 0 indicating a sensed characteristic was not detected and increasing numbers representing an increasing perception of the sensed characteristic. The average measured results from the panel, including two evaluations of each sample of the product per panelist, are reported in Figures 18-24.

[0069] Additionally, for comparison, a control package (i.e., package used for Gamesa Marias brand cookies and labeled with a "C" in Figures 18-24) was also tested in duplicate after being stored under the same specified storage conditions and for the same specified time as the improved resealable package. As with the product in the improved resealable package, the product inside the control package was removed from storage and removed from the control package and various organoleptic properties listed in Figures 18-24 were measured using the trained taste testing panel.

[0070] The average measured results from the panel are reported in Figures 18-24. The organoleptic property includes an asterisk (*) in Figures 18-24 wherein an average measurement for an organoleptic property has a 95% confidence level as measured using ANOVA (Analysis of Variance) in conjunction with Tukey's HSD (honest significant difference test) with the significance level a = 0.05. As an example, in Figure 1 , the Toasted Aroma data is marked with an "asterisk." This means that at least one of the measured averages for this organoleptic property showed a significant difference from other measured averages for this property with a 95% confidence level.

[0071] The specific values associated with the 95% confidence level are also marked with an asterisk in Tables 1-7 below. As an example, in Table 1, the Toasted Aroma average measured value for the control package after 10 weeks in storage is marked with an asterisk. In other words, the average measured Toasted Aroma for the control package after 10 weeks in storage is significantly different with a 95% confidence level relative to other average measured values for the Toasted Aroma. To put it more generally, an average value measuring an organoleptic property is the average of a set of all reported values measuring a package type after a specified storage time. Accordingly, given an asterisk-marked average value for an organoleptic property, the value has a significant difference with a 95% confidence level relative to the other reported average values measuring the organoleptic property (e.g., average reported values associated with a different package type or the same package type and a different specified storage time).

[0072] The average measured values reported by the taste panel for each sample is recorded in Tables 1-7 below.

[0073] As illustrated, Figures 18-24 provide data on both a product stored in control package that is not resealable and a test package that is equivalent to the control package, except that the test package comprises cold seal adhesive on a reseal region located inside a primary seal region of the package wrapper. As can be seen in Figures 18-24, at the end of the specified time, for some embodiments of an improved resealable package (e.g.., the test package), the product stored in the package comprises an organoleptic profile with at least one characteristic that is at least equal to, equal to within +/- 50, 40, 30, 25, 20, 15, 10, 5, 4, 3, 2, or 1 % of, equal to, or no more than at least one characteristic of the control package at the end of the specified time. In some embodiments, the at least one characteristic is a set of characteristics selected from one or a plurality of the characteristics listed in Figures 18-24 or a combination thereof. [0074] Moreover, as described in the Additional Embodiment section herein, some embodiments of a wrapper or a package made from the wrapper can include additional or alternative characteristics, which, in some cases, can significantly impact barrier properties.

[0075] Depending on how a cold seal is applied to a wrapper, the barrier properties of a package comprising cold seal adhesive can be substantially similar to those of an identical package without cold seal adhesive. Nonetheless, if an appropriate cold seal adhesive is not used, it can result in undesirable impacts on the quality of a product contained within the package. For example, a component of the cold seal adhesive, could potentially impact the organoleptic properties of a product or the shelf-life of a product.

[0076] Accordingly, in some embodiments the cold seal adhesive 01 10 has an overall migration rate to a product in contact with the cold seal adhesive, wherein the cold seal adhesive is selected to minimize the overall migration rate of the cold seal adhesive to the product and/or to avoid or minimize effects on the product's organoleptic properties, for example, smell, taste, color and texture. Similarly, in some embodiments, the cold seal adhesive 01 10 comprises a solvent, and the solvent is selected to minimize the overall migration rate of the solvent to a product in contact with the cold seal adhesive and to avoid or minimize effects of the solvent on the product's organoleptic properties, for example, smell, taste, color and texture.

[0077] Although it can be useful to reduce a migration rate of the cold seal adhesive, it can also be useful to mask any off-flavors that might be caused by a cold-seal adhesive. Accordingly, in some embodiments, the cold seal adhesive 0110 comprises an additive to reduce or avoid a smell, taste or both associated with the cold seal adhesive 0110. Moreover, in some embodiments, the cold seal adhesive 01 10 comprises an additive to reduce or avoid transferring a smell, taste or both from the cold seal adhesive 0110 to the product 0206. In some embodiments the cold seal adhesive is a water-based emulsion. An example of a cold seal adhesive that can be used in some embodiments of improved packaging materials as described herein is CO SEAL™ 30061 A cold seal adhesive, available from DowDuPont of Michigan, USA.

[0078] Advantageously, precursors 0100 described herein can be compatible with existing product packaging lines (e.g., manufacturing lines for making a package 0200 that contains a product 0206), whether publicly known or not. For example, the precursor can be compatible with existing product packaging lines in the sense that the addition of the reseal region 0106 (e.g., cold seal adhesive 01 10) does not require modifications of a process used to make a package that contains a product, does not require new equipment, only requires modifications that can be made without new equipment, or a combination thereof. As a further example, a precursor 0100 described herein can be configured for compatibility with an existing form, fill and seal machine 0600.

[0079] With reference again to Figure 2, an embodiment of an improved resealable package 0200 for a product 0206 will now be described. The package 0200 comprises a precursor 0100 as described herein, a product-facing surface 0204, at least one primary seal 0210, and a product containment surface 0202. The wrapper 0102 of the precursor is adhered to itself along at least one primary seal region 0104 of the wrapper 0102 to provide at least one primary seal 0210 for the package 0200, thereby forming a product containment space 0212 within the package 0200. As illustrated, the product containment space 0212 within the package 0200 is bound by the product-facing surface 0204 of the package 0200 and the at least one primary seal 0210 of the package 0200.

[0080] In some embodiments, the product-facing surface 0204 of the package 0200 comprises the reseal region 0106 of the wrapper 0102, cold-seal-adhesive-coated region 0108 of the wrapper 0102, cold seal adhesive 0110, or a combination thereof.

[0081] As illustrated in Figure 2, in some embodiments, the first end seal region 0124 of the wrapper 0102 can provide (e.g., be formed into, be adhered to itself to provide, or a combination thereof) a first end seal 0214 for the package 0200. Similarly, in some embodiments, the second end seal region 0126 of the wrapper 0102 can provide (e.g., be formed into, be adhered to itself to provide, or a combination thereof) a second end seal 0216 for the package 0200.

[0082] With reference again to Figure 2, in some embodiments, the first longitudinal seal region 0128 and the second longitudinal seal region 0130 of the wrapper 0102 are joined (e.g., mutually adhered) to provide a longitudinal seal 0900 for the package 0200.

[0083] With reference to Figure 5, an example of an assembly 0500 is illustrated. The assembly 0500 comprises a package 0200 as described herein and a product 0206 that is contained by the package 0200.

[0084] In some embodiments, the assembly 0500 comprises a product 0206 that is crumbly and/or powdery. Additionally, in some embodiments, the cold seal adhesive 0110 used in the assembly 0500 is effective to provide a seal upon being pressed against itself if up to 10, 20, 30, 40, 50, 60 or 70% of the surface area of the cold seal adhesive 01 10 on the reseal region 0106 of the wrapper 0102 if covered with particles (e.g., crumbs, powder, etc.) of the product 0206.

[0085] In some embodiments, a product 0206 contained by a package 0200 described herein can be a perishable product 0206 (e.g., an edible product 0206 or product intended for human consumption). Additionally, the product 0206 can be divided or divisible into multiple discrete portions, which can be called product units 0208. In some circumstances, every product unit 0208 in a package is not consumed in a single use of the product 0206. Accordingly, it can be advantageous to reseal a package that contains the product 0206.

[0086] Although many different types of products are compatible with a resealable package as described herein, some products are better suited for use with the package than others. Accordingly, in some embodiments, the product 0206 contained by a package has a characteristic selected from the following characteristics: (i) the product 0206 is not so oily that reseal is prevented or is not oily in the sense that drops or pools of unabsorbed oil are present at the surface of the product 0206, (ii) the product 0206 does not comprise a filling that is exposed at the surface of the product 0206 (e.g., to an extent that reseal is prevented or to an extent that drops or pools of filling are present at the surface of the product 0206), (iii) the product 0206 does not comprise chocolate chips on a surface of the product 0206 (e.g., to an extent that reseal is prevented or does not comprise chocolate chips on the surface at all), (iv) the product 0206 comprises crumbles on a surface of the product 0206 and the crumbles cover no more than 5, 10, 15, 20, 30, 40, 50% of the surface of the product 0206 by area, (v) the product 0206 comprises a powder on a surface of the product 0206 and the powder covers no more than 5, 10, 15, 20, 30, 40, 50% of the surface of the product 0206 by area, and (vi) a combination thereof.

[0087] In addition to providing reseal ability, it can be useful for package to have initial barrier properties associated with a primary seal that are adequate to preserve a product for its specified shelf-life. Accordingly, these or other related properties are described herein in the Additional Embodiments section. Additionally, in some embodiments, a package 0200 described herein can remain safe for consumption and/or maintain desired organoleptic properties (e.g., one or any set of properties described herein) for a shelf life of at least 36 weeks in air at 23 °C and 60% relative humidity. Furthermore, in some embodiments, the package 0200 can remain safe for consumption and/or maintain desired organoleptic properties (e.g., one or any set of properties described herein) a shelf life of at least 36 weeks in air at 38 °C and 90% relative humidity.

[0088] In some embodiments, the inventor expects that a package as described herein will be used in conjunction products intended to be consumed by humans or other animals. Accordingly, in some embodiments, the wrapper 0102, cold seal adhesive 01 10, precursor 0100, package 0200 or combination thereof is safe for use with (e.g., safe for contact with) a consumable (e.g., edible) product 0206 or product intended for human consumption. As an example, safe can be defined according to the laws and/or specifications of a governmental agency responsible for permitting food, for example, the FDA in the United States. If the package will contain a product that is to be sold or consumed in another country, safe can be defined in accordance with the laws and/or specifications applicable in the country where the product will be sold or consumed.

[0089] In some embodiments, the wrapper 0102, cold seal adhesive 0110, precursor 0100, package 0200 or combination thereof comprises no lead, no more than an undetectable amount of lead (e.g., no more than 10 mg/kg lead), no cadmium, no more than an undetectable amount of Cadmium (e.g., no more than 5 mg/kg Cadmium), no mercury, no more than an undetectable amount of mercury (e.g., no more than 1 mg/kg mercury), no Chromium, no more than an undetectable amount of Chromium (e.g., no more than 10 mg/kg Chromium), no Chromium IV, no more than an undetectable amount of Chromium IV (e.g., no more than 10 mg/kg of Chromium IV from compounds with Chromium in a +4 oxidation state), or a combination thereof.

[0090] Turning now to Figure 1, Figure 2 and Figure 14, one embodiment of a method 1400 for making an improved package precursor 0100 for an improved resealable package 0200 is illustrated. The method comprises several steps. A first step comprises providing 1402 a wrapper 0102 comprising at least one primary seal region 0104 and a reseal region 0106. A second step comprises depositing 1404 a cold seal adhesive 0110 on the reseal region 0106 to provide a cold-seal-adhesive-coated region 0108 of the wrapper 0102. The reseal region 0106 can be configured to form at least a portion of a product containment surface 0202 of the package 0200. Additionally, the reseal region 0106 can be configured to form at least a portion of a product-facing surface 0204 of the package 0200.

[0091] Turning to Figure 1, Figure 2 and Figure 15, one embodiment of a method 1500 for making an improved resealable package 0200 is illustrated. The method comprises several steps. A first step comprises making 1400 a precursor 0100, for example, as described herein. A second step comprises forming 1504 at least one primary seal 0210 for the package 0200 and forming 1505 a product containment space 0212 of the package 0200. In some embodiments, the forming 1504, 1505 step comprises adhering 1506 at least one primary seal region 0104 of the wrapper 0102 to itself (e.g., first end seal region 0124 or second end seal region 0126); adhering 1510 a first seal region (e.g., the first longitudinal seal region 0128) in the at least one primary seal region 0104 to a second seal region (e.g., the second longitudinal seal region 0130) in the at least one primary seal region 0104; or a combination thereof. [0092] With reference again to Figure 15, in some embodiments, the method comprises a third step of opening 1512 the at least one primary seal 0210 (e.g., breaking, rupturing, or permanently opening at least one primary seal 0210, or a combination thereof).

[0093] With further reference to Figure 15 and Figure 7, in some embodiments, the method comprises a fourth step of resealing 1514 the package 0200 by adhering a first portion 0702 of the reseal region 0106 to a second portion 0704 of the reseal region 0106 (e.g., by pressing the first portion of the reseal region 0106 against the second portion of the reseal region 0106, for example, by folding or twisting the reseal region 0106, by using the cold seal adhesive 0110, or a combination thereof), thereby forming a reseal closure 0700.

[0094] In some embodiments, a fourth step comprises resealing 1514 the package 0200 by adhering a first portion 0702 of the reseal region 0106 to a second portion 0704 of the reseal region 0106 thereby forming a reseal closure 0700.

[0095] In some embodiments, a fifth step comprises reopening 1516 the package 0200 by opening the reseal closure 0700.

[0096] In some embodiments, the method comprises repeating the resealing 1514 and reopening 1516 a plurality of times. Furthermore, in some embodiments, for a subsequent resealing step or for each subsequent resealing step, a first portion 0702 of the reseal region 0106 as adhered to form a subsequent reseal closure 0700, a second portion 0704 of the reseal region 0106 as adhered to form a subsequent reseal closure 0700, or a combination thereof, includes a portion of the reseal region 0106 that was not used to form a previous reseal closure 0700. In some embodiments, the plurality of times that resealing 1514 and reopening 1516 occurs is equal to the number of servings listed on a label of the package 0200 minus 1. Accordingly, in some embodiments, the plurality of times is equal to at least 2, 3, 4, 5, 6, 7, 8, 9, or 10 times.
