Abstract

A polymeric film structure having improved oxygen and moisture barrier characteristics is disclosed. The structure includes a polymeric substrate adapted to receive an oxygen barrier on one side thereof and a moisture barrier on the other side of the oxygen barrier. The oxygen barrier includes polyvinyl alcohol cross-linked with aldehyde containing cross-linking agents in the presence of a catalytic amount of an inorganic acid, preferably sulfuric acid. The moisture barrier is a metallized polymeric composite, preferably metallized oriented polypropylene.
