Abstract
Ream wraps comprising PLA.
Claims42
A ream wrap comprising;
- one or more layers of paper or film and a PLA resin.

- a layer or sheet of cellulosic material;
- and
- a layer of PLA film that is integrally bonded together by means of an adhesive layer.
A method of preparing a composite wrap material comprising:
- laminating a three-layer structure comprising a layer of paper, a PLA layer or film layer and an adhesive layer, using a nip roller apparatus or other suitable laminating device;
- passing said paper and film layers with said adhesive layer thereinbetween through a pair of nip rollers;
- bonding said layers together.
A ream wrapper comprising;
- an unbleached (brown), semi-bleached (tan), or bleached (white) paper;
- and
- a PLA coating.
A method of preparing a ream wrapper comprising;
- mixing PLA with a dye or pigment;
- coating said mixture on either side of an about 30 to 70 pound unbleached (brown), semi-bleached (tan), or bleached (white) paper.
A ream wrapper comprising;
- an unbleached (brown) paper or a semi-bleached (tan) paper;
- and
- a with a white PLA coating.
A ream wrap comprising:
- a first layer of paper;
- a second layer of transparent film;
- and
- a layer of PLA between said first and second layers.
- said paper having holes precut at various locations, said holes being covered by said layer of film.
2 more elements
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.
A method for producing a high strength poly one side ream wrapper comprising;
- blending a PLA resin with a copolymer and/or terpolymer resin;
- feeding said mixture into an extruder die creating an extrudate;
- applying said extrudate to a paper surface between a backing roll and a chill roll creating a coated paper with PLA monomer and copolymer or terpolymer blended into said monomer.
A method for producing a high strength poly one side ream wrapper comprising;
- coextruding a copolymer and/or terpolymer with a PLA layer by feeding said copolymer and/or terpolymer layer and said PLA layer through a coextruder die forming a coextrudate;
- said copolymer and/or terpolymer layer can be blended with PLA;
- applying said coextrudate to a surface of a paper wherein said copolymer and/or terpolymer layer face said paper surface,
- said coextrudate being applied to said paper surface between a backing roll and a chill roll;
- creating a coated paper having one layer of copolymer or terpolymer and one layer of PLA.
2 more elements
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.
A method for producing a high strength poly one side ream wrapper comprising;
- coextruding a copolymer and/or terpolymer layer with a PLA layer by feeding said copolymer and/or terpolymer layer and said PLA layer through a coextruder die to form a coextrudate;
- said copolymer and/or terpolymer layer can be blended with PLA;
- applying said coextrudate to a paper surface with said PLA layer facing said paper;
- said coextrudate applied to said paper surface between a backing roll and a chill roll;
- creating a coated paper with one layer of copolymer and/or terpolymer and one layer of PLA.
2 more elements
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.
A method for producing a high strength poly one side ream wrapper comprising;
- coextruding a layer of copolymer and/or terpolymer and a layer of PLA on each side of a copolymer and/or terpolymer layer by feeding said copolymer and/or terpolymer layer and said PLA layers through a coextruder die forming a coextrudate;
- said copolymer and/or terpolymer layer can also contain PLA;
- applying said coextrudate to a paper surface so that one of said PLA layers faces paper by running said coextrudate and said paper between a backing roll and a chill roll;
- creating a coated paper with one layer of copolymer and/or terpolymer between two layers of PLA.
1 more element
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.
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.
A ream wrap comprising;
- a film layer, PLA layer and a paper layer having an additional layer of PLA coated on said paper.
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.
A method for producing a high strength poly film ream wrapper comprising;
- applying or extruding copolymer and/or terpolymer resins between two sheets of solid plastic PLA film;
- or
- laminating two separate layers of solid plastic PLA film with a copolymer and/or terpolymer resin.
A high strength poly film ream wrap material comprising;
- a first layer comprising a polypropylene, biaxially oriented polypropylene (BOPP), polyester or PLA solid film;
- a second layer comprising a polypropylene, biaxially oriented polypropylene (BOPP), polyester, or PLA solid film;
