Abstract

The present invention provides a monolayer film for use as label feedstock. The present film includes a blend of polyolefin polymer and an ethylene copolymer. In a preferred embodiment, the present film also includes an antiblocking agent.

Claims (22)

1 . A monolayer film for use as label feedstock comprising a polyolefin polymer and an ethylene copolymer.

2 . The monolayer film according to claim 1 further comprising an antiblocking agent.

3 . The monolayer film according to claim 1 wherein said polyolefin polymer is selected from the group consisting of polypropylene homopolymer, random copolymer polypropylene, and combinations thereof.

4 . The monolayer film according to claim 3 wherein said ethylene copolymer is selected from the group consisting of ethylene vinyl acetate, ethylene acrylates, ethylene acrylic acid terpolymers, ethylene vinyl acetate terpolymers, and combinations thereof.

5 . The monolayer film according to claim 3 wherein said polyolefin polymer is a random copolymer polypropylene.

6 . The monolayer film according to claim 3 wherein said ethylene copolymer is ethylene vinyl acetate.

7 . The monolayer film according to claim 3 wherein said polyolefin polymer is a random copolymer polypropylene and said ethylene copolymer is ethylene vinyl acetate.

8 . The monolayer film according to claim 1 wherein said polyolefin polymer is present in a range of from about 30 percent to about 90 percent by weight of said film.

9 . The monolayer film according to claim 1 wherein said ethylene copolymer is present in a range of from about 10 percent to about 70 percent by weight of said film.

10 . A monolayer film for use as label feedstock comprising:

a polypropylene polymer selected from the group consisting of polypropylene homopolymer, random copolymer polypropylene, and combiantions thereof,

ethylene vinyl acetate; and

an antiblocking agent.

11 . The monolayer film according to claim 10 wherein said polypropylene polymer is present in an amount of from about 30 percent to about 70 percent by weight of said film.

12 . The monolayer film according to claim 11 wherein said ethylene vinyl acetate is present in an amount of from about 29 percent to about 69 percent by weight of said film.

13 . The monolayer film according to claim 10 wherein said ethylene vinyl acetate is present in an amount of from about 29 percent to about 69 percent by weight of said film.

14 . The monolayer film according to claim 10 wherein said polypropylene polymer is a random copolymer polypropylene.

15 . The monolayer film according to claim 14 wherein said random copolymer polypropylene is present in an amount of from about 29 percent to about 69 percent by weight of said film.

16 . A monolayer film for use as label feedstock comprising:

random copolymer polypropylene in an amount of about 50 percent by weight of said film;

ethylene vinyl acetate in an amount of about 49 percent by weight of said film; and

an antiblocking agent in an amount of about 1 percent by weight of said film.
