Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a biaxially oriented moistureproof polypropylene film having excellent moistureproofness, lamination strength, and thickness accuracy. SOLUTION: The biaxially oriented moistureproof polypropylene film having excellent moistureproofness, lamination strength, and thickness accuracy is obtained from a polypropylene composition comprising 97-75 wt.% propylene polymer composition composed of a propylene homopolymer (A) and a propylene-α-olefin copolymer (B) with an α-olefin content of 0.1-1.8 mol% and 3-25 wt.% tackifier.
