ABSTRACT:
A polymeric film having superior oxygen barrier properties comprising at least five layers with two exterior layers independently selected from the group consisting of an aliphatic polyamide and an aliphatic/aromatic polyamide, an interior layer of ethylene vinyl alcohol copolymer or a blend of poly(m-xylylene adipamide) and ethylene vinyl alcohol copolymer, and a modified polyolefin adhesive layer between each exterior layer and the interior layer.
