PROBLEM TO BE SOLVED: To obtain a polypropylene film excellent in low-temperature heat sealing property, blocking resistance, scratch resistance and transparency after passage of time and its laminate excellent in adhesiveness of a substrate to polypropylene film layer. SOLUTION: This propylene film comprises a propylene-α-olefin random copolymer of propylene with ethylene or a 4-12Cα-olefin and the propylene-α- olefin random copolymer has <=2.5wt.% amount extracted with n-decane at ordinary temperature and 120-145 deg.C melting point and 0.5-15.0g/10min melt flow rate. This polypropylene film laminate is obtained by using a layer selected from among a polyamide film, a polyester film, a polyvinyl chloride film and an aluminum foil or a drawn polypropylene film layer as a substrate and laminating a polypropylene film on at least either one surface of the substrate. |
