Abstract
A vinylidene chloride polymer composition comprising a vinylidene chloride polymer and a concentrate comprising a blend of a high viscosity, high molecular weight silicone polymer and a carrier polymer, e.g. high density polyethylene, the concentrate being present in an amount sufficient to improve the extrudability of the vinylidene chloride polymer. The vinylidene chloride composition can be fabricated into flexible and rigid containers, both in monolayer and multilayer structures for use in the preservation of food, drink medicine and other perishables.
