Zusammenfassung:To provide an ethylene resin composition that yields a molded article capable of being heat-sealed at lower temperatures compared to conventional ethylene resin-based films, and demonstrates superior moldability, blocking resistance, and transparency.SOLUTION: An ethylene resin composition (Z) comprises (A) an ethylene-α-olefin copolymer, which is a copolymer composed of ethylene and a C4-10 α-olefin, satisfying requirements (1)-(4), and (B) an ethylene-α-olefin copolymer, which is a copolymer composed of ethylene and a C4-10 α-olefin, satisfying requirements (a)-(b). The ethylene-α-olefin copolymer (A) has a mass fraction (WA) of 1 mass% or more and 90 mass% or less, and the ethylene-α-olefin copolymer (B) has a mass fraction (WB) of 10 mass% or more and 99 mass% or less (where, the total of WA and WB is 100 mass%). There are also provided a molded article, a film and a multilayer film.SELECTED DRAWING: None 【課題】従来公知のエチレン系樹脂から得られるフィルムと比較して、得られる成形体が低温でヒートシール可能であり、かつ、成形性、耐ブロッキング性、および、透明性に優れるエチレン系樹脂組成物を提供すること。【解決手段】下記要件(1)~(4)を満たすエチレンと炭素数4~10のα-オレフィンとの共重合体であるエチレン-α-オレフィン共重合体(A)と、下記要件(a)~(b)を満たすエチレンと炭素数4~10のα-オレフィンとの共重合体であるエチレン-α-オレフィン共重合体(B)と、を含み、前記エチレン-α-オレフィン共重合体(A)の質量分率(WA)が1質量%以上90質量%以下であり、前記エチレン-α-オレフィン共重合体(B)の質量分率(WB)が10質量%以上99質量%以下である(ただし、WAとおよびWBの合計を100質量%とする)エチレン系樹脂組成物(Z)、成形体、フィルムおよび多層フィルム。【選択図】なし
