Abstract

[PROBLEMS] To provide a polypropylene resin film which is made of a polypropylene resin produced inexpensively and efficiently by the gas phase method, has excellent blocking resistance and satisfactory slip properties, is less apt to crease when wound into a roll, and has satisfactory processability in bag formation and printing. [MEANS FOR SOLVING PROBLEMS] The multilayered polypropylene resin film is one comprising a base layer which is made mainly of a polypropylene resin and seal layers which are made mainly of a polyolefin resin and are disposed respectively on the front and back sides of the base layer. The polypropylene resin constituting the base layer and seal layers has been formed by the gas phase method. The film has been regulated so that the coefficient of dynamic friction as measured in a 40°C atmosphere, the air escape index, and the haze thereof satisfy given requirements.
