Resealable bag with inelastic deformable polymer
The resealable bag has a main body including a resealing layer. The resealable bag is selectively positionable between an open, unsealed position and a closed, sealed position. When the resealable bag is in the closed, sealed position, the resealing layer is in a deformed shape. Advantageously, the resealable bag can be repeatedly rolled and sealed, and unrolled and unsealed, as desired without the use of additional integrated or non-integrated sealing mechanisms.
1. A resealable bag, comprising:
a main body including a resealing layer,
the resealable bag is selectively positionable between an open, unsealed position, and a closed, rolled, and sealed position;
wherein when the resealable bag is in the closed, rolled, and sealed position, the resealing layer is in a deformed shape; and
wherein the resealable bag is formed from an inelastic deformable polymer that includes an admixture of poly(lactic acid) and cellulose and contains no metal, and the inelastic deformable polymer has a predetermined shape fixity configured to permit a user to manually manipulate the resealable bag to the closed, rolled, and sealed position where the inelastic deformable polymer retains the deformed shaped.
2. The resealable bag of claim 1 , wherein the main body has a plurality of layers in addition to the resealing layer, each of the plurality of layers selected from a group consisting of sealant, thermoplastic resin, biaxially oriented polypropylene, paper, synthetic paper, overprint varnish, plastic, polymer film, cellulosic film, bioplastic film, polypropylene fabric, and combinations thereof.
3. The resealable bag of claim 1 , wherein the resealing layer extends a length and a width of the main body of the resealable bag.
4. The resealable bag of claim 1 , wherein the resealing layer extends from a bottom seal of the resealable bag to a top seal of the resealable bag.
5. The resealable bag of claim 1 , wherein the inelastic deformable polymer consists essentially of an admixture of poly(lactic acid) and cellulose.
6. The resealable bag of claim 1 , wherein the inelastic deformable polymer consists of an admixture of poly(lactic acid) and cellulose.
7. The resealable bag of claim 1 , wherein the inelastic deformable polymer includes a shape memory polymer.

12. The resealable bag of claim 10 , wherein the main body is formed from a panel, and the panel is formed from the resealing layer and an outer layer.
13. The resealable bag of claim 12 , wherein the outer layer is formed of a biodegradable or recyclable film.
14. The resealable bag of claim 12 , wherein the resealing layer is laminated with the outer layer.
15. The resealable bag of claim 12 , wherein the panel further includes an inner layer.
16. The resealable bag of claim 15 , wherein the inner layer is formed of a biodegradable or recyclable barrier.
17. The resealable bag of claim 15 , wherein the resealing layer is secured between the inner layer and the outer layer.
18. The resealable bag of claim 15 , wherein the resealing layer is laminated between the inner layer, and the outer layer, and each of the inner layer and the outer layer includes cellulose.
19. The resealable bag of claim 9 , wherein the resealing layer has a thickness between about 25 microns and about 1.0 millimeters.
20. The resealable bag of claim 9 , wherein the resealing layer has a first end and a second end, the first end overlapping the second end to form a vertical seal.
