Three-layer wrapping and a process for manufacturing a packaging using the same
One embodiment provides a wrapping, comprising a first layer of synthetic polymeric material; a second layer of synthetic polymeric material; and a layer of natural material sandwiched between at least a portion of the first and second layers; wherein the first and second layers are wider than the layer of natural material and extend beyond opposing ends of the layer of natural material to form tabs, the tabs comprising said first and second layers sandwiched together without the layer of natural material therebetween. Methods of making and using are disclosed.
1. A wrapping, comprising:
a first layer of synthetic polymeric material;
a second layer of synthetic polymeric material; and
a layer of natural material sandwiched between at least a portion of the first and second layers;
wherein the first and second layers are wider than the layer of natural material and extend beyond opposing ends of the layer of natural material to form tabs, the tabs comprising said first and second layers sandwiched together without the layer of natural material therebetween.
2. The wrapping of claim 1 , wherein the natural material comprises one or more of paper, cotton, cellulosic fiber, kenaf, hemp, jute, flax, sisal, abaca, bleached pulp fiber, unbleached pulp fiber, recycled pulp fiber, or a combination of two or more thereof.
3. The wrapping of claim 1 , wherein the natural material comprises one or more cellulosic fibers.
4. The wrapping of claim 1 , wherein the natural material is paper.
5. The wrapping of claim 1 , wherein the natural material is recycled paper.
6. The wrapping of claim 1 , wherein one or both of the first and second layers comprise one or more polymeric material, synthetic paper, organic polymer, biopolymer, carbohydrate, polysaccharide, starch, cellulose, glycogen, hemi-cellulose, chitin, fructan inulin, lignin, pectic substance, gum, protein, cereal, vegetable protein, animal protein, gluten, whey protein, gelatin, colloid, hydro-colloid, polylactic, polygalactic, cellulosic film, thermoplastic polymer, thermoset polymer, polyolefin, polypropylene, polyethylene, LDPE, HDPE, polystyrene, polyurethane, polyvinylhalide, PVC, polyester, polyethylene terephthalate, polyamide, nylon, biaxially oriented polypropylene, non-hydrocarbon polymer, homopolymer, copolymer, oriented polymer, or any combination of two or more thereof.
7. The wrapping of claim 1 , wherein the both the first and second layers are the same material.
8. The wrapping of claim 1 , wherein the one or both of the first and second layers comprise one or more of thermoplastic polymer, thermoset polymer, polyolefin, polypropylene, polyethylene, LDPE, HDPE, polystyrene, polyurethane, polyvinylhalide, PVC, polyester, polyethylene terephthalate, polyamide, nylon, biaxially oriented polypropylene, homopolymer, copolymer, oriented polymer, or any combination of two or more thereof.
9. The wrapping of claim 1 , wherein the one or both of the first and second layers comprise, one or more of polypropylene, polyethylene, LDPE, HDPE, polystyrene, polyurethane, polyvinylhalide, PVC, polyester, polyethylene terephthalate, polyamide, nylon, biaxially oriented polypropylene, homopolymer, copolymer, oriented polymer, or any combination of two or more thereof.
10. The wrapping of claim 1 , wherein the one or both of the first and second layers biaxially oriented polypropylene.
11. The wrapping of claim 1 , wherein one or both of the first and second layers are single layer or multilayered films.
12. The wrapping of claim 1 , wherein one or both of the first and second layers are 10 to 500 microns thick.
13. The wrapping of claim 1 , wherein one or both of the first and second layers is clear biaxially oriented polypropylene having a thickness of 30 to 160 microns.
14. A method for making the wrapping of claim 1 , comprising:
contacting the first layer with the layer of natural material, the first layer being wider than the layer of natural material and extending beyond opposing ends of the layer of natural material; and
contacting the second layer with the layer of natural material and, at least where the first layer extends beyond the opposing ends, with the first layer to form the tabs.
15. The method of claim 14 , further comprising heat sealing the first and second layers together at the tabs.
16. The method of claim 14 , further comprising cutting the wrapping.
17. The method of claim 14 , further comprising heat sealing the first and second layers to the layer of natural material.
18. A wrapped article, comprising: the wrapping of claim 1 ; and an article, wrapped therein.
19. The wrapped article of claim 18 which is a paper ream package.
