<p>An extrudable vinylidene chloride composition is useful in packaging films where good thermal stability during processing, and oxygen barrier properties in the finished film are desirable. The composition, and film made therefrom, comprises 100 parts by weight of an extrudable vinylidene chloride copolymer; at least 0.1 parts by weight of an acid acceptor such as tetrasodium pyrophosphate; and between 1 and 10 parts by weight of a dienophile such as ethylene/butyl acrylate/maleic anhydride terpolymer. A polymeric lubricating agent can optionally be included in the composition and film. A film comprising a sealant layer; first and second intermediate layers comprising a material selected from polyamide, polyester, and ethylene vinyl alcohol copolymer; a barrier layer comprising vinylidene chloride copolymer; and an abuse layer is also disclosed.</p> |
