A film includes a copolymer having a tetrafluoroethylene-based unit and an ethylene-based unit, in which the film has a haze of from 1.2% to 8.0%, an ultraviolet reflectance of less than 17.0%, and a thickness of from 250 to 400 μm.

Film and method of producing the same

To provide a dielectric film which is excellent in dielectric properties and stability in the electric corrosion test and which is suitable for producing a high-precision printed board. A roll film comprising a melt-processable fluororesin as the main component and having a thickness of from 1 to 100 μm, the dimensional change rate of which is less than 1.0%, in terms of an absolute value, in each of MD and TD, when heated at 150° C. for 30 minutes and then cooled to 25° C., based on the dimension at 25° C.

Roll film, method for producing roll film, method for producing copper-clad laminate and method for producing printed board

An agricultural fluorine-resin film and a greenhouse that can increase yield of crops even in high-eave houses are provided. In the agricultural fluorine-resin film containing fluorine-resin, one surface has an uneven surface, a transmittance at a wavelength of from 300 to 800 nm is from 20% to 70%, and a transmittance Tbelow is 75% or more. Transmittance T: Transmittance of a laminate at a wavelength of from 300 to 800 nm, obtained by laminating the resin film and a test film, in which the uneven surfaceof the resin film is completely filled with water, and the test film which has a thickness of 50 &#x3bc;m, is formed of only an ethylene-tetrafluoroethylene copolymer, and has a transmittance at a wavelength of from 300 to 800 nm of 94% and an arithmetic average roughness Ra of both surfaces of 0.04 &#x3bc;m is laminated on the resin film.
