<P>PROBLEM TO BE SOLVED: To obtain a polypropylene-based film excellent in scratch resistance and hardly generating fish-eyes when forming the film. <P>SOLUTION: This propylene-based resin composition includes a particle composition (component C) comprising 10-75 wt.% of a propylene-based polymer particle (component A) having an average particle diameter of 700-1,500 μm, and 90-25 wt.% of a propylene-based polymer particle (component B) having an average particle diameter of 100-600 μm, where particles having ≤200 μm particle diameter is 20-100 wt.%, provided that the total weight of the component A and component B is 100 wt.%; and an inorganic microparticle (component D), having an average particle diameter of 0.5-10 μm and apparent specific gravity of 0.1-0.5 g/cm<SP POS="POST">3</SP>, of 1-20 pts.wt. based on 100 pts.wt. of the component C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
