<p>PROBLEM TO BE SOLVED: To provide a polyethylene resin composition which is excellent in moldability and also to provide a polyethylene container which is obtained by thermal-molding or blow-molding of the polyethylene resin composition. SOLUTION: This polyethylene resin composition comprises (a) a polyethylene resin and (B) a crosslinked polyethylene and satisfies the following characteristics (a)-(g): (a) an indissoluble component of 0.1-20 wt.%, (b) MRF of 0.05-10 g/10 minutes, (c) a flow activation energy obtained from the range of 160-220 deg.C is not higher than 35 kJ/mol, (d) a melt tension is not less than 50 mN, (e) (the melt tension)>110-100 xlog (MFR), (f) a nonlinear parameter which is an index of a strain curing of an elongation viscosity is not less than 3, and (g) the melt tension which is obtained after extrusion is conducted at 190 deg.C is not less than 50% of the melt tension obtained before extrusion.</p> |
