PROBLEM TO BE SOLVED: To provide a biaxially oriented polypropylene film which is excellent in uniformity of projections, has a high roughness density, and is excellent in recyclability, which is suitable for packaging, condensers and the like. . SOLUTION: The melt tension (M) measured at 230 ° C. S) (cN) and melt flow rate (MFR) (g / 1 0 min), log (MS)> -0.56 log (MF R) A biaxially oriented polypropylene film made of polypropylene satisfying a relational expression of +0.74. |
