PURPOSE: Provided is a propylene resin composition, which has excellent rigidity, impact resistance and moldability, as well as high slidability and heat resistance, and shows excellent closing/opening property when formed into a cap. Also, its use is provided. CONSTITUTION: The propylene resin composition comprises: 85-95 parts by weight of ethylene-propylene block copolymer (A) having a melt flow rate of 2-20 g/10 min. at 230 deg.C, a homo part stereo-regularity of 0.960 and a total ethylene content of 6-12 wt%; and 5-15 parts by weight of high density polyethylene (B) having a melt flow rate of 30-60 g/10 min. at 190 deg.C and a density of 0.957-0.966 g/cm3. The propylene resin composition may further comprise 0.05-0.3 parts by weight of a nucleating aid based on 100 parts by weight of the ethylene-propylene block copolymer (A).
