A coextruded multiple layer oriented film comprises a core layer of a blend of ethylene vinyl alcohol copolymer and polyamide, two intermediate adhesive layers, and two outer layers of a blend of linear low density polyethylene, linear medium density polyethylene, and ethylene vinyl acetate copolymer. A preferred embodiment of the multilayer film exhibits excellent optics and shrink properties while providing high oxygen barrier especially useful in food packaging applications.
An oriented multilayer film comprising: (a) a cross-linked core layer comprising a blend of an ethylene vinyl alcohol copolymer and a polyamide resin, said blend forming between about 5% and 25% of the total film thickness; (b) two cross-linked interior layers each comprising an adhesive resin; (c) two cross-linked outer layers each comprising a three-component blend of a linear low density polyethylene, a linear medium density polyethylene, and an ethylene vinyl acetate copolymer; and (d) said film having a total thickness ranging from about 0.75 to 1.5...
