Abstract:
A polypropylene-based resin composition comprising:0.5 to 10% by weight of a propylene-based polymer component (A1) obtained by polymerizing a monomer mainly composed of propylene, having an intrinsic viscosity [&eegr;]A1 measured in tetralin at 135Â° C. of 5 dl/g or more and a melting peak temperature TmA1 measured by a differential scanning calorimeter of 130 to 160Â° C.; and 90 to 99.5% by weight of a propylene-based polymer component (A2) obtained by polymerizing a monomer mainly composed of propylene, having an intrinsic viscosity [&eegr;]A2 measured in tetralin at 135Â° C. of less than 5 dl/g, wherein the total amount of (A1) and (A2) is 100% by weight, wherein the polypropylene-based resin composition has a melt flow rate (MFR) measured according to JIS-K-6758 of 5 to 150 g/10 minutes.
