<P>PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition excellent in transparency and excellent in impact resistance at low temperatures, and to provide a film containing the same. <P>SOLUTION: The propylenic resin composition contains 60 to 90 wt.% of (component (A)) a polypropylene-based polymer component having a structural unit originated from propylene as a main structural unit, and 10 to 40 wt.% of (component (B)) a propyelene-ethylene copolymer component having a content of a structural unit originated from ethylene of 20 to 50 wt.%, and satisfies all of the following requirements (1), (2) and (3): (1) the melting temperature of the component (A) is ≥162°C; (2) the molecular weight distribution of the component (A) is ≥1.0 and ≤3.0; and (3) the limiting viscosity of the component (A) (the ratio ([η]B/[η]A) of a limiting viscosity ([η]B) of the component (B) to a limiting viscosity ([η]A) of the component (A)) is 1.3<[η]B/[η]A≤3.0. <P>COPYRIGHT: (C)2012,JPO&INPIT |
