Laminate film and packaging bag.

Problem to be solved. 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.
