PROBLEM TO BE SOLVED: To provide a polypropylene type film excellent in water resistance, moisture proofing and color development in printing, easy to remove after adhesion, and useful as a packaging film or an adhesive label. SOLUTION: The film comprises, as a core layer, a foamed polypropylene type film containing any one of inorganic fine particles, inactive organic fine particles and an incompatible polymer and comprises on both surfaces of it, as surface layers, polypropylene type films which contain either of inorganic fine particles and inactive organic fine particles and which substantially are not foamed. The ratio of the thicknesses of both surface layers is 1:5-1:16, and, in the thickness of≤50μm of the laminated film, the all light transmittance of the film is 5-45%, the haze is 50-95% and the internal haze is≥50% of the haze value.
