Abstract

Ream wraps comprising PLA.

Claims (30)

1 . A high strength poly one-side ream wrapper comprising:

copolymer and/or terpolymer resins;

said copolymer and terpolymer resins comprising butene, hexene, and/or octene with ethylene feed stocks;

said copolymer or terpolymer are applied to a paper surface alone or blended with PLA resins.

2 . The ream wrapper of claim 1 wherein said paper comprises an additional coat of PLA resin.

3 . A high strength poly one side ream wrapper comprising;

a coextruded coated paper having one layer of copolymer and/or terpolymer on top of said paper and one layer of PLA on top of said copolymer or terpolymer layer; said copolymer and/or terpolymer layer can also contain PLA.

4 . A high strength poly one side ream wrapper comprising;

a coextruded coated paper having one layer of PLA on top of said paper layer and a layer of copolymer and/or terpolymer on top of said PLA layer;

said copolymer and/or terpolymer layer can be blended with PLA.

5 . A high strength poly one side ream wrapper comprising;

a poly coated paper having one layer of PLA on top of a paper layer followed by a layer of copolymer and/or terpolymer having on top of it a layer of PLA;

said copolymer and/or terpolymer layer can also contain PLA.

6 . A composite wrap material comprising;

a layer or sheet of cellulosic material and a layer of PLA film material that are integrally bonded together by means of an adhesive layer comprising PLA interposed thereinbetween.

7 . The composite wrap material of claim 6 wherein said PLA film layer and/or said adhesive layer function to provide a moisture vapor barrier to protect contents packaged within said wrap material.

8 . The composite wrap material of claim 6 wherein said wrap material provides a clear or transparent wrap such that a consumer can see said paper layer laminated to said PLA film layer.

9 . The composite wrap material of claim 6 wherein one or more of said layers contains a pigment to provide coloration.

10 . The composite wrap material of claim 6 wherein said wrap is provided with a high gloss print surface or a standard paper print surface.

11 . The composite wrap material of claim 6 wherein said paper material and/or said film is a metalized material.

12 . The composite wrap material of claim 6 wherein said paper is printed before lamination so that the print shows through said film layer.

13 . A ream wrap comprising;

a film layer, PLA layer and a paper layer having an additional layer of PLA coated on said paper.

14 . The ream wrap of claim 13 wherein said inner layer of PLA bond to said outer film layer through heat.

15 . A high strength poly film ream wrapper comprising;

two sheets of PLA film laminated together with a layer of copolymer and/or terpolymer resins;

said copolymer and/or terpolymer resins comprising butene, hexene, and/or octene with ethylene in feed stocks.

16 . An insulation facing material comprising;

a coextruded coated paper material comprising; a first layer of paper, a second layer of PLA resin material and a third outside sealant layer of low melt polymer resin, comprising, PLA;

wherein all three layers are integrally bonded together.
