摘要： The propylene-based polymer composition of the present invention includes 41 to 95 parts by weight of a propylene-based polymer (A) having a Tm measured by DSC of not less than 120° C. and not more than 170° C., and 59 to 5 parts by weight (provided that the total of (A) and (B) is 100 parts by weight) of a propylene/ethylene/α-olefin copolymer (B) that contains 84.0 to 60.0 mol % of constitutional units derived from propylene, 15.0 to 30.0 mol % of constitutional units derived from ethylene, and 1.0 to 10.0 mol % of constitutional units derived from an α-olefin having 4 to 20 carbon atoms and has a B-value of not less than 0.9 and not more than 1.5. This polymer composition is excellent in transparency, low-temperature impact resistance, and mechanical properties (flexibility or rigidity, etc.) and also excellent in heat resistance.
