摘要: A multilayer film useful in food packaging includes a core layer (10) of ethylene vinyl alcohol copolymer, two interior adhesive layers (12,14), and outer (16,18) comprising polymeric materials or blends thereof such as linear low density polyethylene, with medium polyethylene acetate very polyethylene. Ethylene propylene polypropylene, may also be used the layers. Optional nylon included on each surface layer. Orientation coextrusion provides heat-shrinkable film.
