PROBLEM TO BE SOLVED: To provide a resin composition for blow molding by improving the strength at the joining part, impact resistance and blow moldability of the resin inside a die in blow molding. SOLUTION: The composition comprises component (A): 50 to 89 pts.wt. of a propylene polymer having an MFR of from 0.1 to 5 g/10 min and a density of from 0.890 to 0.915 g/cm<3> , component (B): 5 to 20 pts.wt. of a straight-chained, low-density polyethylene having a wide molecular weight distribution, an MFR of from 0.1 to 10 g/10 min, a density of form 0.850 to 0.935 g/cm<3> and a Q value of 5 or larger, component (C): 5 to 20 pts.wt. of a straight-chained, low- density polyethylene having a narrow molecular weight distribution, an MFR of from 0.1 to 10 g/10 min, a density of from 0.850 to 0.935 g/cm<3> and a Q value of 4 or smaller, component (D): 1 to 15 pts.wt. of an ethylene/C >= 3α-olefin copolymer elastomer having an MFR of from 0.1 to 10 g/10 min and a density of from 0.840 to 0.900 g/cm<3> . |
