Zusammenfassung:	PURPOSE:A composition providing a film having improved printability and adhesiveness of metallized face, preventing unsatisfactory winding properties, with keeping improved impact resistance and heat sealability, obtained by blending a specific polypropylene with a specified polyethylene in a fixed ratio. CONSTITUTION:(A) 96-80wt% polypropylene, a crystalline propylene-alpha-olefin copolymer having >=70wt% propylene component and =0.940g/cm density in a melt flow ratio of the component B/the component A of >=0.7. The blend may be mixed with 0.01-0.30wt% phenolic antioxidant or phosphorus-based antioxidant having >=500 molecular weight and 0.0-1.0wt% inorganic filler such as metal-substituted type zeolite, etc., having
