Abstract
Vinylidene chloride polymer compositions comprising a vinylidene chloride polymer and from about 2 to about 12 weight percent of a glycerin ester provide films which exhibit oxygen transmission rates sufficiently low to protect gassy cheeses from spoilage but sufficiently high to let any excess CO.sub.2 produced during the cheese curing process escape from the packaged gassy cheeses.
