ABSTRACT:
This invention relates to films made from vinylidene chloride copolymers. Specifically, this invention relates to a method and compositions for lowering the oxygen permeability and enhancing the thermal stability and enhancing the melt shear stability of monolayer and multilayer packaging films having a layer of vinylidene chloride copolymer film by adding an organic silicon polymer to the vinylidene chloride copolymer. The conventional stabilizer/plasticizer combination of epoxy resin and 2-ethyl-hexyl diphenyl phosphate may be eliminated from the vinylidene chloride copolymer.
