摘要

A blow molding ethylene resin composition satisfies the following requirements [a], [b], [c] and [d] at the same time:
[a] the melt flow rate (MFR) at a temperature of 190°C under a load of 21.6 kg is in the range of 1.0 to 15 g/10 min;
[b] the density is in the range of 955 to 970 kg/m 3 ;
[c] the number of methyl branches per 1000 carbon atoms is less than 0.1 according to 13 C-NMR;
[d] the tensile impact strength measured at -40°C in accordance with JIS K 7160 is not less than 270 kJ/m 2 .
