  • Process for producing multilayer structures having a layer formed from a blend of an ethylene-alpha-olefin interpolymer and an ethylene-alkyl acrylate interpolymer
    Patent number: 6827807
    Abstract: There is disclosed a process for producing a multilayer structure, the film of which has particular utility as a masking film for the substrate layer. The process comprises the cast film process producing a monolayer film from a specified blend of ethylene-alpha-olefin and ethylene-alkyl acrylate interpolymers, or a multilayer film, at least one of the layers formed from the blend of interpolymers, and pressing the cast film process produced monolayer or multilayer film onto a polymeric or glass substrate layer that is maintained at a temperature of about 38 to about 80° C. during the pressing of the layers.
    Type: Grant

  • Process for producing ethylene-&agr;-olefin interpolymer films
    Patent number: 6649694
    Abstract: There is disclosed a process for producing films from ethylene-&agr;-olefin interpolymers, which films have, in combination, the properties of improved surface haze, improved stiffness, and improved color. The process involves incorporating from about 0.1 to less than 1% by weight, of a functionalized ethylene homopolymer or functionalized ethylene interpolymer into an ethylene-&agr;-olefin interpolymer-containing composition, and forming a film from the composition.
