See full text

An ethylene-based resin satisfying simultaneously the following requirements [a] to [c] is excellent in strength and moldability and is suitably used for a blow molded article (a hollow molded article). [a] The environmental stress cracking resistance (ESCR), T, at 50° C. is 500 hours or more in the case of a flexural modulus of 1000 MPa to 1500 MPa and is 100 hours or more in the case of a flexural modulus of 1500 MPa to 2000 MPa, as measured according to ASTM-D-1693, [b] the melt tension at 190° C. is 50 (mN) or more and [c] the melt breaking drawing rate is 90 (m/min) or less.
