Abstract: PURPOSE:To obtain a fluoroplastic laminated film excellent in water and oil repellency, antistaining properties, non-tackiness, releasability, base material protective properties and humidity resistance and capable of being prepared inexpensively by laminating a composition based on a fluorine-containing polymer to a non-stretched or uniaxially stretched thermoplastic resin film and further stretching the laminate uniaxially or biaxially before heat-treating the same. CONSTITUTION:A thermoplastic resin being a material for a base film is dissolved in a proper solvent and the solvent solution is formed into a film by a casting method while a fluoroplastic composition is laminated and bonded to the surface of the film as it is or after uniaxial stretching. In a method for forming the fluoroplastic composition layer on the base film, the fluoroplastic composition is formed into an emulsion or solvent solution which is, in turn, applied to the base film to be dried. The laminate thus obtained is further uniaxially or biaxially stretched to enhance the physical properties of the base film layer and subsequently heat-treated not only to remove the internal stress of the fluoroplastic layer but also to thermally fix the base film layer.
