<P>PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition being excellent in balance of blocking resistance, rigidity and low temperature impact resistance. Ž<P>SOLUTION: The polypropylene-based resin composition contains a polypropylene-based copolymer containing 50-95 wt.% of a polymer component (component A) in which a structural unit derived from propylene is a main component, and 5-50 wt.% of a polymer component (component B) of propylene, ethylene and ≥4C α-olefin in which a content (X) of a structural unit derived from propylene is 10≤X<50 wt.%, a content (Y) of a structural unit derived from ethylene is 50<Y≤70 wt.%, and a content (Z) of a structural unit derived from the ≥4C α-olefin is 0<Z≤20 wt.% (provided that a total of X, Y and Z is made to 100 wt.%), and an anti-blocking agent.
