PROBLEM TO BE SOLVED: To provide a thermally fusible propylene polymer laminated film excellent in low temperature heat sealability, sealability and laminating strength under a high speed and low pressure condition and having blocking resistance and slip properties, transparency or the like suitable for a packing material. SOLUTION: The thermally fusible propylene polymer laminated film comprises a thermal fusion-bonding layer, which is obtained from a propylene polymer composition (C) comprising a propylene/α-olefin copolymer (A) wherein a peak temperature (Tp) calculated from a crystal melting curve based on DSC and a difference (Te-Ts) between a melting start temperature (Ts) and melting end temperature (Te) are within a specific range and a 1-butene/α-olefin copolymer (B) wherein the content of 1-butene and a melting point (Tm) based on DSC are within a specific range, an intermediate layer, which is obtained from a propylene polymer composition (F) comprising a propylene polymer (D) and straight chain low density polyethylene (E), and a laminating layer obtained from the propylene/α-olefin copolymer (A).
