Abstract
A polymeric film structure having improved oxygen, flavor/odor, grease/oil and moisture barrier characteristics is disclosed. The structure includes a polymeric core sandwiched between an oxygen barrier on one side thereof and a moisture barrier on the other side of the polymeric core. 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 coating of polyvinylidene chloride, which also enhances the oxygen barrier of the polymeric film structure.
