POLYETHYLENE RESIN COMPOSITION, MOLDED BODY THEREOF AND CONTAINER

Japanese Patent JP2017179300

A

PROBLEM TO BE SOLVED: To provide a polyethylene resin composition excellent in hollow moldability, environmental stress crack resistance and impact resistance and capable of manufacturing a molded article excellent in appearance, and provide a molded body and a container consisting of the same.SOLUTION: There is provided a polyethylene resin composition containing a specific polyethylene component (A) of 10 to 40 mass%, a specific polyethylene component (B) of 10 to 80 mass% and a specific polyethylene component (C) of 10 to 80 mass% and satisfying properties (1) to (5). Property (1):MFR is 0.1 to 1 g/10 min. Property (2):HLMFR is 10 to 50 g/10 min. Property (3):HLMFR/MFR is 40 to 140. Property (4):density is 0.940 to 0.965 g/cm. Property (5):an inflection point of elongation viscosity caused by strain hardening is observed in a double logarithmic plot of elongation viscosity η(t) (unit:Pa sec.) and elongation time t (unit:sec.) measured at temperature of 170°C and elongation strain rate of 0.1 (unit:1/sec.).SELECTED DRAWING: None
