PROBLEM TO BE SOLVED: To obtain a polypropylene film excellent in steam barrier properties. SOLUTION: A polypropylene film consists of a substrate layer and the surface layer formed on one surface or both surfaces of the substrate layer and the substrate layer contains a polypropylene resin. In this case, the MFR of the polypropylene resin contained in the surface layer is 5 g/10 min or more and the isotactic index (II) thereof is 95% or more. The resin constituting the surface layer contains 200 ppm or less of an oxidation inhibitor. |
