  • Patent number: 7754300
    Abstract: Articles comprise a monolayer blown film prepared from a composition comprising at least one vinylidene chloride polymer and at least one plasticizer wherein at least one vinylidene chloride polymer comprises vinylidene chloride and at least one alkyl acrylate, selected from methyl acrylate, ethyl acrylate, or butyl acrylate or a combination thereof in an amount of from 2.5 to 9 mole percent of the monomer content of the vinylidene chloride polymer and wherein the plasticizer is present in an amount of from 1 to 15 parts by weight per hundred parts of polymer, wherein the article is selected from a package, a container, a laminate, sausage casing or combination thereof, particularly a sausage casing, wherein at least 4 of designated characteristics are present. The invention also includes processes for making articles of the invention and films used therein.

  • Publication number: 20080274245
    Abstract: The present invention includes a multicomponent structure comprising at least two components having a tie layer or adhesive layer directly between them, the tie layer comprising at least one olefin unsaturated ester copolymer and at least one photoinitiator and optionally a crosslinking enhancer. The tie layer is preferably irradiated with sufficient actinic radiation to result in increased interlayer adhesion strength between the two components as compared with the interlayer adhesion strength before treatment with the actinic radiation or between the components having a tie layer of the same composition except without the added photoinitiator or crosslinking enhancer. Without the photoinitiator, optionally crosslinking enhancer, and radiation the interlayer adhesion of the components is preferably less than 55 N/m.

  • Publication number: 20020014717
    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.

  • Patent number: 5986003
    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.

  • Patent number: 5340844
    Abstract: An improved polystyrene foam having less corrugation is disclosed which uses carbon dioxide as the blowing agent and 1-30 weight percent endothermic agent, such as water, with the weight based on the total carbon dioxide blowing agent and endothermic agent weight. This combination of carbon dioxide and endothermic agent decreases the corrugation of the thermoplastic foam, while just slightly increasing density, when the process parameters, including throughput, are equivalent to using only carbon dioxide. The process an also allow an increased foaming temperature and greater process throughput of an equivalent density thermoplastic foam at approximately equivalent corrugation levels when compared to the use of only using only carbon dioxide.
