ABSTRACT:
A coextruded multiple layer oriented film comprises a core layer of ethylene vinyl alcohol copolymer, two intermediate adhesive layers, and two outer layers of a blend of linear low density polyethylene and a very low density polyethylene. A preferred embodiment of the multilayer film exhibits improved heat seal strengths, and excellent optics and shrink properties while providing high oxygen barrier especially useful in food packaging applications.
