Abstract

A multilayer film with an oxygen transmission rate of at least 10,000 cc/mil/24 hour@STP. The film is particularly suited for the packaging of fresh seafood. The film has a first neat and a second layer which serves as a high 02-transmission layer. The first layer has a thickness of from 2 to 20 percent of a total thickness of the multilayer film. The second layer comprises at least one member selected from the group consisting of: (i) ethylene/butyl acrylate copolymer, (ii) homogeneous ethylene/alpha-olefin copolymer having a density of from 0.86 to 0.91 g/cc; (iii) heterogeneous ethylene/alpha-olefin copolymer having a density of from 0.89 to 0.91 g/cc; (iv) ethylene/methyl acrylate copolymer having a methyl acrylate mer content of from 20 to 24 mole percent; (v) ethylene/vinyl acetate copolymer having a vinyl acetate mer content of from 10 to 30 mole percent; and (vi) styrene butadiene block copolymer. The film is at least 38 microns (1.5 mils) thick. The invention also pertains to a bag made from the film, as well as a packaged product utilizing the film.
