PROBLEM TO BE SOLVED: To provide an olefin resin film which is best-suited for use as a support film for a sticker or a marking film and prevents the generation of a curl, bleeding of a low molecular weight component, blocking of a film roll and the like from occurring and exhibits high workability, printability, applicatability of a pressure-sensitive adhesive agent, productivity and the like. SOLUTION: This co-extruded multilayered film comprises a printed resin layer (A) containing a propylene resin (a1), an intermediate resin layer (B) containing a propylene resin (b1) and an ethylene resin (b2) and an inner resin layer (C) containing a propylene resin (c1) composed of a propylene copolymer (c11) with a propylene content of not less than 90 wt.% and 2-20 wt.% of an ethylene/propylene copolymer rubber (c12) and an ethylene resin (c2). The co- extruded multilayered film is formed of both corona discharge-treated sides. |
