PROBLEM TO BE SOLVED: To provide a propylene polymer film for vapor deposition having improved low-temperature heat sealing properties, blocking properties and hermetic sealing properties without inhibiting adhesiveness to a vapor-deposited film of an inorganic compound and wettability and a vapor-deposited film of a propylene polymer and a laminated film. SOLUTION: The propylene polymer film for the vapor deposition is obtained from a propylene-α-olefin copolymer (A) having 110-140°C peak temperature (Tp) and <45°C difference (Te-Ts) of the crystal melting starting temperature (Ts) and the melting end temperature (Te) determined from a crystal melting curve based on a DSC (differential scanning colorimeter). The vapor-deposited film of the propylene polymer is prepared by vapor-depositing an inorganic compound on one surface thereof. COPYRIGHT: (C)2005,JPO&NCIPI
