PROBLEM TO BE SOLVED: To provide a large-sized blow molding polyolefinic resin composition which has a high melt strength, allows little drawdown of parison when blow- molded, has a good appearance and has a uniform thickness in section. SOLUTION: The composition comprises, against 100 pts.wt. polyolefinic resin (A) having a melt flow rate(MFR) from 0.1 to 7 g/ 10 min, a polytetrafluoroethylene-containing mixed powder (B) comprising a polytetrafluoroethylene particle with a particle size of 10μm or smaller, and an organic polymer at an amount which gives an amount of the polytetrafluoroethylene content of from 0.01 to 20 pts.wt.
