PROBLEM TO BE SOLVED: To obtain the subject molded product capable of manifesting excellent blow moldability and mechanical characteristics by combining a polyethylene having reforming mechanical characteristics and a moldability improving material capable of imparting excellent blow molding characteristics. SOLUTION: This molded body is obtained by molding a polyethylene composition comprising (A) a polyethylene prepared by carrying out the polymerization according to a slurry polymerization method in the presence of a preferably supported and geometrically restricted type single site catalyst and (B) a low- density polyethylene at >=1 wt.% and <=12 wt.% mixing ratio of the component B. The component A is composed of 30 70 pts.wt. polyethylene having physical properties such as <=0.950 g/cm<3> density and >=5,000 and <=100,000 weight- average molecular weight and 70-30 pts.wt. polyethylene having physical properties such as >=0.910 and <=0.950 g/cm<4> density and >=110,000 and <=1,500,000 weight-average molecular weight. The component B has physical properties such as >=0.910 and <=0.930 g/cm<3> density. |
