METALLIZED COMPOSITE FILM STRUCTURE AND METHOD

摘要

A metallized film combination comprising an oriented polypropylene substrate layer, at least one surface of which having a coating of a vinyl alcohol homopolymer or copolymer hydrolyzed to at least 95 % at a pH of greater than 5.0, said coating having a metal layer thereon. The high pH PVOH hydrolysis conditions provide a metallized product of high metal adhesion and good water and oxygen barrier properties.
