PROBLEM TO BE SOLVED: To provide a polyethylene resin material capable of achieving a balance of impact resistance, stress crack resistance, molding stability and fluidity, and adjusting moldability without changing molecular weight distribution and composition distribution. I will provide a. SOLUTION: The density (d) is 0.90 to 0.97 g / cm 3 , 19 MFR 0.001 to 300 dg / at 0 ° C and 21.18N load min, a polyethylene resin material satisfying the conditions of an extensional viscosity parameter (SHP) of 0.10 to 2.5, particularly a density of 0.90 to 0.97 g / cm 3 , 190 ° C., 211.82 N load 19 HLMFR 0.001 to 100 with 0 ° C and 211.82N load dg / min, molecular weight distribution (Mw / Mn) 3.0 to 8.0, comonomer sequence distribution (CS D) Ethylene polymer (A) satisfying the conditions of 0 to 3.0 10 to 90% and other ethylene polymer (B) 90 to 10 % Of a polyethylene-based resin material and a molded article made of the polyethylene-based resin material. |
