PROBLEM TO BE SOLVED: To provide a metal deposited polypropylene film having excellent low-temperature sealability, blocking resistance and adhesive properties of the film with the deposited metal film and a packaging material made of the film. SOLUTION: The metal deposited polypropylene film is obtained by forming a deposited thin film of a metal or metal oxide on the surface of a film made of polypropylene having a melt flow rate of 2.0 to 15.0g/10min and ambient temperature n-decane extract amount of 2.5wt.% or less. A packaging material is formed of the metal deposited polypropylene film or a laminate containing the metal deposited polypropylene film. The polypropylene film has excellent adhesive properties of the film made of polypropylene and the deposited thin film made of the metal or metal oxide, low-temperature sealability, blocking resistance and oxygen barrier properties. The packaging material has excellent low-temperature sealability, blocking resistance and charging machine suitability of a material to be packaged. |
