PROBLEM TO BE SOLVED: To obtain a propylene resin film having flexibility suitable for a packaging film or the like, and manufacturing method therefor. SOLUTION: A propylene resin film is composed by sequentially laminating an outer layer 1 composed of random polypropylene, an interlayer 2 composed of random polypropylene containing 20-100 wt.% olefin resin, and an inside layer 3 composed of random polypropylene. The olefin resin used for the interlayer 2 is composed of propylene copolymer, where rubber component composed of ethylene-propylene component is 30-60 wt.%, ethylene content in the rubber component is 20 wt.% or higher, and crystallinity index is 40-70%, density is 0.885-0.915 g/cm<3> , and MFR is 5 g/10 min. or lower. |
