ABSTRACT:
Disclosed are multi-layer thermoformable film constructions. At least one layer of the multi-layer construction is a polymer blend of: (a) 40–95% by weight of an ethylene-acrylic acid or methacrylic acid copolymer or of an ethylene-acrylic acid or methacrylic acid-alkyl acrylate or alkyl methacrylate copolymer with 30–70% of the acid groups of the acrylic acid or methacrylic acid of either copolymer neutralized with metal ions, and (b) 5–60% by weight of a metallocene catalyzed linear polyethylene.
