    The invention provides a polypropylene type laminated film for holograms which allows easy formation of irregularities constituting a hologram by embossing and has excellent secondary processability, e.g. bag processing by heat sealing. The laminated film consists of a surface layer of a propylene type copolymer overlying at least one side of a substrate layer of a polypropylene type resin, and the propylene type copolymer has a peak top temperature, Tp, of the maximum peak of 70-100 DEG C, with a half-value width of the peak of lower than 10 DEG C, in the elution temperature-elution amount curve by the continuous temperature-raising elution fractionation. Irregularities constituting a hologram are formed on the surface of the surface layer by embossing.
