  • Publication number: 20230079561
    Abstract: The present invention addresses the problem of providing a film for a film capacitor that has high heat resistance, self-healing properties, and excellent productivity, wherein the film has a resin layer A having a melting point of 180° C. or higher and/or a glass transition temperature of 130° C. or higher and a layer B thinner than the resin layer A in at least the outermost layer of the film, the oxygen content of the layer B is 1.0% by mass or more, when a dynamic friction coefficient is measured on the same surface of two outermost layer surfaces, the surface having a higher dynamic friction coefficient is defined as an a-plane and the surface having a smaller dynamic friction coefficient is defined as a b-plane, and when a dynamic friction coefficient between the a-planes is defined as ?daa, and a dynamic friction coefficient between the a-plane and the b-plane is defined as ?dab, ?daa>?dab and ?dab?1.2 are satisfied.

  • Patent number: 11358374
    Abstract: A laminated film exhibits a certain adhesive property to various adherends having shapes or different irregularity shapes. The laminated film includes a resin layer A on one surface of a substrate and a resin layer B on the other surface. The resin layer A has a ten-point average surface roughness Rz(a) of 1.5 ?m or more and 5.0 ?m or less and a storage elastic modulus G? at 25° C. and 1 Hz of 3.0×105 Pa or more.
