Ethylene Resin Composition And Molded Body

Abstract: [Problem] To provide an ethylene resin capable of producing by excellent moldability a molded body (especially a film) having excellent mechanical strength and an excellent balance of transparency and blocking resistance. [Solution] An ethylene resin composition (Z) including an ethylene-a-olefin copolymer (A) that satisfies requirements (1)-(4) and an ethylene-a-olefin copolymer (B) that satisfies requirements (a)-(c). (1) Density is 890-935 kg/m3 (2) MFR (190°C, 2.16 kg load) is 0.1 g/10 min to less than 3.0 g/10 min (3) MT (melt tension)/?* (shear viscosity) is 1.20×10-4 to 2.90×10-4 g/P (4) 0.01×10-13 × Mw3.4 = ?0 (zero shear viscosity) = 3.5×10-13 × Mw3.4 (a) Density is 890-930 kg/m3 (b) MFR (190°C, 2.16 kg load) is 0.1-10 g/10 min (c) 1.90×10-4 × Mw0.776 = [?] = 2.80×10-4 × Mw0.776
