Patent ID: 7338708

Claim:
A multilayer film, comprising: (A) a first layer which is a first outer film layer and which serves as a heat seal layer, the first layer comprising a first polymer, the first layer having a thickness of from 2 to 20 percent of a total thickness of the multilayer film; and (B) at least one second layer which serves as a high oxygen transmission layer, the at least one second layer consisting essentially of at least one member selected from the group consisting of: (i) ethylene/butyl acrylate copolymer, (ii) homogeneous ethylene/alpha-olefin copolymer having a density less than 0.92 g/cc; (iii) ethylene/methyl acrylate copolymer having a methyl acrylate mer content of from 20 to 24 mole percent; (iv) ethylene/vinyl acetate copolymer having a vinyl acetate mer content of from 10 to 30 mole percent; (v) styrene butadiene block copolymer; and the at least one second layer having a thickness of from 80 to 98 percent of the total thickness of the multilayer film; the total thickness of the multilayer film being from about 1.5 mils to about 2.5 mils, and the film having an oxygen transmission rate from about 10,000 to about 15,000 cc/m 2 /24 hr @STP.
