More Information
Summary:Provided are a laminated film and an adhesive tape. The laminated film of the present invention includes a base material layer, a roughness-expressing layer, and a fine unevenness-erasing layer in the stated order, in which: the base material layer contains a thermoplastic resin; the roughness-expressing layer contains at least one kind of a resin component (A) selected from polyethylenes, ethylene-vinyl acetate copolymers, propylene-based polymers, and olefin-based thermoplastic elastomers; the fine unevenness-erasing layer contains a thermoplastic resin (B); an arithmetic average surface roughness Ra on the surface on the side of the fine unevenness-erasing layer is 1.0 [mu]m to 3.0 [mu]m; and the haze value of the laminated film is 30% or less.
