<P>PROBLEM TO BE SOLVED: To provide a heat fusion property propylene-based polymer laminated film which excels in low-temperature heat sealability, envelope bonding heat seal strength, sealability, lamination strength, and has blocking resistance, and impact resistance, slip characteristics, transparency, glossiness or the like which is suitable for a packaging material. Ž<P>SOLUTION: A heat fusion property propylene-based polymer film has a heat fusion layer obtained from a propylene copolymer composition (D) which includes: a propylene-α-olefin copolymer (A) in which a peak temperature (Tp) obtained from a crystal melting curve based on DSC is 110-140°C, and the difference (Te-Ts) between a melting starting temperature (Ts) and a melting end temperature (Te) is less than 45°C; an ethylene-α-olefin random copolymer (B) having 0.865-0.910 g/cm<SP>3</SP>of a density; and a propylene-α-olefin copolymer (C) in which a propylene content is 55-80 wt.% and a crystal melting heating value based on DSC is 10-80 Joule/g. The laminated film is provided. In addition, the application of the laminated film is for all foods, daily necessaries and miscellaneous goods, medicines, and can be suitably used also for an industrial material-related packaging material.
