Abstract: A process for making a thermoplastic film by the blown film extrusion process comprises extruding a molten thermoplastic polymer through a tubular die to form a tube of molten polymer, contacting the inner surface of the tube of molten polymer as it exits the die with an aqueous solution of a water-soluble polysaccharide ether, inflating the tube of molten polymer to form a blown tubular film and then collapsing the blown film to a flat web. The thermoplastic film has on its surface a coating of a water-soluble polysaccharide ether.

Abstract: A vinylidene chloride polymer composition comprises a vinylidene chloride polymer and a concentrate comprising a blend of a high viscosity, high molecular weight silicone polymer and a carrier polymer, for example 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.
