Zusammenfassung:	PURPOSE: A propylene-based resin composition is provided to have excellent heat seal strength, impact resistance in low temperature, and blocking resistance, and to obtain a film hardly generating orange peel due to a heat treatment. CONSTITUTION: A propylene-based resin composition comprises 100.0 parts by weight of resin composition and 0.01-0.1 parts by weight of a specific acrylate-based compound and/or a specific phosphite-based compound. The resin composition comprises 70-90 weight% of propylene-based copolymer, and 30-10 weight% of ethylene-A-olefin-based copolymer if which density is 900-940 kg/m^3 and molecular weight distribution is 1-3. The propylene-based copolymer contains 50-90 weight% of a polymer component which has a main structural unit originated from propylene, and 50-10 weight% of an ethylene-propylene copolymer component of which structural unit content is 20-60 weight% originated from ethylene.
