LAMINATE FILM AND PACKAGING BAG

To provide a laminate film which has suitable impact resistance, in particular, has excellent impact resistance at low temperature, and is excellent in easily tearing property.SOLUTION: There is provided a laminate film in which a surface layer (A) containing a polypropylene-based resin as a main resin component, an intermediate layer (B) containing linear low density polyethylene and a cyclic olefin-based resin and a heat seal layer (C) containing linear low density polyethylene as a main resin component are laminated, where a content of the linear low density polyethylene in the resin composition contained in the intermediate layer (B) is 65-85 mass%, and a content of the cyclic olefin-based resin is 15-35 mass%. The laminate film can achieve suitable impact resistance and easy tearing property.SELECTED DRAWING: None 【課題】好適な耐衝撃性、特に低温下での優れた耐衝撃性を有し、易引き裂き性に優れた積層フィルムを提供する。【解決手段】ポリプロピレン系樹脂を主たる樹脂成分とする表面層（Ａ）、直鎖低密度ポリエチレンと環状オレフィン系樹脂とを含有する中間層（Ｂ）及び直鎖低密度ポリエチレンを主たる樹脂成分とするヒートシール層（Ｃ）が積層された積層フィルムであり、中間層（Ｂ）に含まれる樹脂成分中の直鎖低密度ポリエチレンの含有量が６５〜８５質量％、環状オレフィン系樹脂の含有量が１５〜３５質量％である積層フィルムにより、好適な耐衝撃性と易引き裂き性とを実現できる。【選択図】なし
