(57) [Problem] To provide a polyethylene molded article having excellent mechanical strength and rigidity. SOLUTION: The density (d A ) is 0.95 to 0.98 g / cm 3 , [Eta] ethylene polymer (A) 20 to 90 wt% and there is a range of 0.5~3.0dl / g, a density (d B) is from 0.91 to 0. 965 g / cm 3 , 80 to 10% by weight of an ethylene polymer (B) having [η] in the range of 1.0 to 10 dl / g, wherein at least one of the above (A) and (B) is An ethylene-based polymer produced using a metallocene catalyst, d A And the ratio of d B (d A / d B ) is greater than 1 and the density is 0.9. 40-0.970 g / cm 3 , MFR 0.005-20 g / 10 Min, MFR and melt tension (MT) are log (MT) Satisfies ≧ -0.4 log (MFR) +0.7 and diameter swell ratio is 1.3 Use more than 5 ethylene polymer compositions. |
