    摘要: Provided is a laminated film that enables easy material recycling and has excellent impact strength. Formed on top of each other are: a layer A containing an ethylene polymer (A) having 80 mol% or more of an ethylene-derived structural unit; a layer B containing an ethylene polymer (B) having 70 mol% or more of an ethylene-derived structural unit and an inorganic filler (A); a layer C containing an ethylene polymer (C) having 70 mol% or more of an ethylene-derived structural unit; a barrier layer and/or an adhesive layer; a layer D containing an ethylene polymer (D) having 70 mol% or more of an ethylene-derived structural unit and an inorganic filler (B), the ethylene polymer (D) constituting at least 75% by mass but less than 99.5% by mass of the layer D; and a layer E containing an ethylene polymer (E) having 70 mol% or more of an ethylene-derived structural unit.
