发明名称 Oxygen barrier oriented film
摘要 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.
