<p>A biaxially oriented polypropylene film which has a melt flow rate of from 1 to 12 g/10 min and in which the melt viscosity thereof as measured with a rotational rheometer at a shear rate of 0 rad/sec ( eta 0), the melt viscosity thereof as measured with the rheometer at a shear rate of 10 rad/sec ( eta 10), and the MFR thereof satisfy the relationship (1): <MATH> The biaxially oriented polypropylene film has, when subjected to heat sealing/cutting, a high sealing strength at the heat-sealed part and reduced fluctuations in sealing strength, has excellent stiffness suitable for bag-forming and filling and sealing, and is excellent in transparency and gloss.</p> |
