摘要： The present invention provides biaxially oriented multilayer fluoropolymer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a thermoplastic homopolymer or copolymer and an intermediate adhesive layer which is preferably a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the thermoplastic layer allows the fluoropolymer layer to be biaxially stretched many times its original length. A high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film. Coextrusion processing can be done at higher temperatures, i.e. in the range of from at about 280 °C to about 400 °C. These temperatures allow films to be produced in the absence of polymer degradation and film melt fracture.

摘要： Multilayered films produced by coextruding or laminating films comprised of at least one layer of polymethylpentene, at least one layer of a polyamide and an intermediate polymeric adhesive layer. The polyamide layer allows the polymethylpentene layer to be stretched up to 6 times its original length. Such a high orientation ratio for the multilayered film increases the mechanical strength and toughness properties of the film. The multilayered films are suitable for use as release films for high temperature composite applications such as printed circuit boards.

摘要： The present invention provides coextruded or laminated films having at least one layer of a fluoropolymer homopolymer or copolymer, a layer of a cyclic olefin homopolymer or copolymer and an intermediate adhesive layer. Such films have a high moisture barrier property and are substantially transparent.

摘要： Multilayer fluoropolymer films are formed from a layer of a fluoropolymer, a tie layer and a thermoplastic layer. The tie layer is a blend of an olefin-containing polymer, preferably at least one polyolefin having at least one functional moiety, such as an unsaturated carboxylic acid or anhydride thereof, and a styrene-containing polymer. Preferably, the fluoropolymer is a chlorotrifluoroethylene homopolymer or copolymer and the thermoplastic layer is a polyethylene. The preferred styrene-containing polymer is a styrene-ethylene-butylene-styrene block copolymer. These films exhibit increased adhesion between the layers as compared to a multilayer structure in which the tie layer is formed only from the olefin-containing polymer. The multilayer films are useful in packaging applications, including pharmaceutical packaging.
