BACKGROUND

[0002] The present disclosure relates to bags, and particularly to storage bags. More particularly, the present disclosure relates to storage bags for agricultural products.

SUMMARY

[0003] According to the present disclosure, a multilayer film is used to form a storage bag for storing agricultural products. The storage bag includes a polymeric tube formed to include a storage space and a fill aperture arranged to open into the storage space at a first end. A first closure is coupled to an opposite second end of the polymeric tube to close the second end.

[0004] In an illustrative embodiment, the multilayer film is configured to minimize circumferential creep in the polymeric tube during filling of the storage bag with agricultural products and to minimize puncture and tearing of the storage bag so that amounts of agricultural products stored in the storage space are maximized.

[0005] In another illustrative embodiment, the polymeric tube is formed from a multilayer film comprising an inner layer configured to define, at least in part, the storage space, an outer layer located in spaced-apart relation to the inner layer, and a core layer located between the inner and outer layers.

The inner layer may include a polyethylene polymer. The outer layer may include a polyethylene polymer. At least one of the layers of the multilayer film is configured to minimize puncture of the multilayer film by objects extending through the multilayer film from the inner layer through the outer layer so that puncture and tearing of the multilayer film is minimized. [0007] In another illustrative embodiment, at least one of the layers of the multilayer film is configured to minimize circumferential creep in the polymeric tube during filling of the storage bag by agricultural products so that puncture and tearing of the storage bag is minimized.

It is within the present disclosure for the weight of the polymeric tube 12 to fall within one of the following weight ranges: less than about 1000 lbs, less than about 900 lbs, and about 100 lbs to about 1000 lbs. In one example, the weight of the polymeric tube 12 with a length of 200 feet may fall within one of several different ranges: about 100 lbs to about 400 lbs, about 100 lbs to about 300 lbs, and about 200 lbs to about 300 lbs.

[0024] In one example, the polymeric tube 12 comprises a ground to ground measurement 36 as shown in Fig. 3. As described herein, the ground to ground (GTG) measurement refers to the distance from a contact point 38 of the polymeric tube 12 in contact with the ground to a second contact point 40 of the polymeric tube 12 in contact with the ground as shown in Fig. 3. This measurement may be taken from the contact point 38 to the second contact point 40 by measuring around the circumference of the polymeric tube 12, excluding the distance of the polymeric tube 12 that is in direct contact with the ground. The GTG measurement of the polymeric tube 12 may be dependent upon the dimensions, the material stored in the polymeric tube 12, the pressure and fill rate of the polymeric tube 12, the materials used to make the polymeric tube 12, and other relevant factors.

Illustratively, each composition is formed by processing the formulation. Illustratively, each formulation of layer 28, 31, 32, 33, 34, 35, and 30 may be added to a hopper on an extrusion machine and heated to produce a molten material in the extruder. The molten material of each layer 28, 31, 32, 33, 34, 35, and 30 may be co-extruded to produce multilayer film 24. Films as disclosed herein may be made by many methods, including, but not limited to, blown film co-extrusion and cast film, co-extrusion processes, or any other suitable processes.

In another example, at least one layer of the multilayer film 24 comprises a polyethyleneincompatible polymer. In another example, at least 2 layers of the multilayer film 24 comprise a polyethylene-incompatible polymer. In another example, 1, 2, 3, or 4 layers of the multilayer film 24 comprise a polyethylene polymer. In another example, 1, 2, or 3 layers of the multilayer film 24 comprise a polyethylene polymer.

[0033] The term “incompatible polymer” may be understood to be a polymer that may form an immiscible blend with a second polymer to which it is being referred. An immiscible blend can also be referred to as a heterogeneous blend. An example, without limitation, of a second polymer to which an incompatible polymer is being referred is polyethylene (PE). An incompatible polymer described herein may form an immiscible blend with polyethylene, and may be referred to as a polyethylene-incompatible polymer. Examples of polyethylene-incompatible polymers, include but are not limited to, polypropylene, polystyrene, ethylene-vinyl alcohol copolymer, nylon (polyamide), and combinations thereof. A polyethylene-incompatible polymer described herein may be provided by fine particles. Examples of polyethylene-incompatible polymers, include but are not limited to, a polypropylene, a polypropylene fine particle composition, a polystyrene, a polystyrene fine particle composition, an ethylene vinyl alcohol copolymer, an ethylene vinyl alcohol copolymer fine particle composition, a nylon, a nylon fine particle composition, or any combination thereof.

[0038] Another feature of multilayer film 24 according to various aspects of the present disclosure is that the multilayer film 24 can be recycled. Recyclable means that a material can be added (such as regrind) back into an extrusion or other formation process without segregation of components of the material. As an example, a multilayer film 24 does not have to be manipulated to remove one or more materials or components prior to re-entering the extrusion process. In one example, it may be advantageous to limit the weight percentage of the polyethylene-incompatible polymer of the multilayer film 24 to provide for the recycling of the multilayer film 24.

In an example, the outer layer 28 of the multilayer film 24 can comprise PIR (post industrial recycled) resin, PCR (post consumer recycled) resin, or combinations thereof.

[0040] In another example, it may be advantageous to limit the weight percentage of the polyethylene-incompatible polymer of the multilayer film 24 to control material cost. In one example, it may be advantageous to limit the weight percentage of the polyethylene-incompatible polymer of the multilayer film 24 to control cost of the multilayer film 24. In another example, it may be advantageous to limit the weight percentage of polystyrene polymer of the multilayer film 24 to control cost of the multilayer film 24.

Tn another example, the multilayer film 24 has a stretch of less than or equal to 12% in a 24 hour high temperature creep-resistance test.

[00184] EXAMPLES

[00185] Example 1

[00186] An exemplary storage bag formed from multilayer film 1 in accordance with certain aspects of the present disclosure was made by a 7-layer co-extrusion, blown process with a diameter of 14 ft and a gauge of 6.5-9.5 mil. Multilayer film 1 comprises polystyrene (PS) in 3 layers. The percentages by weight of the components of multilayer film 1 are shown in Table 1. Total PS content of the film is 7%.

[00187] Table 1. Composition of multilayer film 1.

[00188] Example 1A

[00189] An exemplary storage bag formed from multilayer film 1A in accordance with certain aspects of the present disclosure was made by a 7-layer co-extrusion, blown process with a gauge of about 9 mil ± about 20%. The percentages by weight of the components of multilayer film 1A are shown in Table 2. Multilayer film 1A comprises polystyrene (PS) in 2 layers. Total PS content of the film is 2.8%. The properties of multilayer film 1A are shown in Table 3.

[00192] Example 2: TD Creep Resistance Test

[00193] An exemplary custom-designed creep-resistance test was developed to determine the creep-resistance of the storage bag formed from multilayer film 1A in accordance with certain aspects of the present disclosure. For comparison, a 1 cm wide sample was taken from both a comparative polyethylene-only bag that does not include polystyrene, and the storage bag formed from multilayer film 1A, both oriented in the TD (Transverse Direction). The test is done in a heated oven at 60 °C for 24 hours using a 1 kg weight on a 1 cm wide and 10 cm long film sample. The length of the film is measured at 0 hours and 24 hours twice to calculate the percent stretch (%) when the weight is on.

[00194] The comparative polyethylene-only bag exhibited significant stretching during the creep-resistance test, reaching up to 115% of its original length. In contrast, the bag formed from multilayer film 1A comprising the polystyrene demonstrated superior performance, with stretching consistently measuring less than 110% under the same test conditions.
