Zusammenfassung:To provide a technique for improving extrudability of a polyolefin-based recycled resin without largely impairing its mechanical strength.SOLUTION: A polyolefin-based recycled resin composition (Z) contains a polyolefin-based recycled resin, and an ethylene-α-olefin copolymer (A) which is a copolymer of ethylene and α-olefin having 4 to 10 carbon atoms and satisfies a specific requirement, wherein a mass fraction (W1) of the polyolefin-based recycled resin is 50 mass% or more and 95 mass% or less, and a mass fraction (W2) of the ethylene-α-olefin copolymer (A) is 5 mass% or more and 50 mass% or less (provided that the total of W1 and W2 is 100 mass%).SELECTED DRAWING: None 【課題】ポリオレフィン系再生樹脂の機械的強度を大きく損ねることなく、その押出性を改良する技術を提供すること。【解決手段】ポリオレフィン系再生樹脂と、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って、特定の要件を満たすエチレン-α-オレフィン共重合体(A)とを含み、前記ポリオレフィン系再生樹脂の質量分率(W1)が50質量%以上95質量%以下であり、前記エチレン-α-オレフィン共重合体(A)の質量分率(W2)が5質量%以上50質量%以下である(ただし、W1とW2との合計を100質量%とする。)ポリオレフィン系再生樹脂組成物(Z)。【選択図】なし
