| Zusammenfassung: | 1. Field of the Invention
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 [ ]measured in tetralin at 135° C. of 5 dl/g or more and a melting peak temperature Tmmeasured by a differential scanning calorimeter of 130 to 160° C., 90 to 99.5% by weight of a propylene-based polymer component (A2) obtained by polymerizing a monomer mainly composed of propylene, intrinsic viscosity [ ]measured in tetralin at 135° C. of less than 5 dl/g. |
