    摘要： A film includes a core layer including a homogeneous random alpha-olefin/cyclic olefin copolymer; and first and second outer layers including an olefinic polymer; the film having Young's modulus between about 50,000 and about 200,000 psi, free shrink between about 10% and about 80% at 240° F., and shrink tension of less than about 400 psi, or a shrink force of between about 20 and about 180 grams, at 240° F. First and second intermediate layers including an ethylene copolymer having a melt index less than about 2 g/10 minutes can be optionally included. Alternatively, a film includes a core layer including an ethylene copolymer having melt index less than about 2 g/10 minutes; first and second intermediate layers including a homogeneous random alpha-olefin/cyclic olefin copolymer; and first and second outer layers including an olefinic polymer; the film having properties as disclosed above.

    摘要： This invention relates to extruding films made from vinylidene chloride copolymers. Specifically, this invention relates to a method for lowering the oxygen permeability and enhancing the thermal stability and enhancing the melt shear stability of packaging films having a layer of vinylidene chloride copolymer film by adding a processing aid such as an epoxy resin to vinylidene chloride copolymer of low molecular weight. The conventional stabilizer/plasticizer combination of epoxy resin and 2-ethyl-hexyl diphenyl phosphate may be employed with the vinylidene chloride copolymer. The layer of vinylidene chloride copolymer can be as thin as 0.18 mil.
