Beschreibung
Zusammenfassung:	To provide a film that offers an improved balance between cleanliness and mechanical strength, compared to conventionally known films composed of ethylenic polymers.SOLUTION: A film is composed of a polymer material, where the polymer material is a material that contains an ethylene-α-olefin copolymer (A) and any thermoplastic resin (B), substantially excluding the other components, where the copolymer (A) is a copolymer of an ethylene with a C4-10 α-olefin, satisfying specific requirements (1)-(6).SELECTED DRAWING: None 【課題】従来公知のエチレン系重合体からなるフィルムと比較してクリーン性と機械的強度とのバランスに優れたフィルムを提供すること。【解決手段】重合体材料からなるフィルムであって、前記重合体材料が、エチレン－α－オレフィン共重合体（Ａ）、および任意の熱可塑性樹脂（Ｂ）以外の成分を実質的に含有しない材料であり、前記共重合体（Ａ）が、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り、特定の要件（１）～（６）を満たす共重合体である、フィルム。【選択図】なし
