Abstract:
A polymeric film structure having improved oxygen, flavor/odor, grease/oil and moisture barrier characteristics is disclosed. The structure includes a polymeric substrate (10) adapted to receive an oxygen barrier (12) on one side thereof and a moisture barrier (14) on the other side of the oxygen barrier, or 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 (12) includes polyvinyl alcohol cross-linked with aldehyde containing cross-linking agents in the presence of a catalytic amount of inorganic acid, e.g., sulfuric acid. The moisture barrier (14) is cellulosic material, preferably box board; metallized polymeric composite, preferably metallized oriented polypropylene; or a coating of polyvinylidene chloride.
