Examples 1-8 are repeated with the following exceptions. Instead of using the PVdC set forth in Table I, a pellet having the following composition is employed: the pellet contains about 96.5 weight percent of a vinylidene chloride interpolymer; about 1.5 weight percent ethylene vinyl acetate; about 1.2 weight percent tetrasodiuum pyrophosphate; and about 0.8 weight percent of epoxidized soybean oil. The vinylidene chloride interpolymer comprises from about 99.8 weight percent of a vinylidene chloride copolymer formed from a monomer mixture comprising 94 weight percent vinylidene chloride and about 6 weight percent methyl acrylate; and about 0.2 weight percent of epoxidized soybean oil. The vinylidene chloride copolymer has a major melting point of 165° C. and a weight average molecular weight of 90,000.
