PROBLEM TO BE SOLVED: To provide a polyethylene resin molding material for blow molding that exhibits excellent blow molding processing properties such as flowability and the like and excellent product properties such as impact resistance and the like, particularly one that gives a blow-molded item exhibiting excellent strengths of a pinch-off fused portion and an excellent shape. SOLUTION: The polyethylene resin molding material for blow molding comprises a resin composition containing a component (A), a component (B), a component (C) and a component (D) at a specific ratio, and has (i) an MFR of 0.1-0.5 g/10 min and an HLMFR of 10-50 g/10 min and (ii) a density of 0.950-0.960 g/cm<SP>3</SP>. The component (A) is an ethylene polymer having specific properties polymerized using a chromium catalyst. The components (B) and (C) are each an ethylene polymer having specific properties polymerized using a titanium catalyst (provided that the components (B) and (C) are different). The component (D) is an ethylene polymer having specific properties polymerized using a titanium catalyst. COPYRIGHT: (C)2008,JPO&INPIT |
