POLYETHYLENE-BASED RESIN COMPOSITION AND LAMINATED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a polyethylene-based resin composition having low extrusion load, and to provide a laminated product excellent in scratch resistance of the surface. SOLUTION: The resin composition is obtained by melting and kneading (A) 100 pts.wt. ethylene-α-olefin copolymer satisfying the requirements (a) to (d) with (B)≥10 pts.wt. and <200 pts.wt. ethylene-α-olefin copolymer satisfying the requirements (e) to (g) and (C)≥10 pts.wt. and <50 pts.wt. low-density polyethylene obtained by high-pressure method and satisfying the requirements (h) to (i). (a) The density is 880-930 kg/m3. (b) The MFR is 31 to 100 g/10 min. (c) The copolymer satisfies the relationship represented by the formula Tm<-1.8×SCB+140. (d) Carbon number ofα-olefin is≥5 and≤12. (e) The density is 900-940 kg/m3. (f) The MFR (melt flow rate) is 0.1-20 g/10 min. (g) The ratio of Mw/Mn is≥3. (h) The density is 910-935 kg/m3. (i) The MFR is 0.1-10 g/10 min.
