PROBLEM TO BE SOLVED: To provide a sealant film which exhibits a high laminating strength in relation to a substrate layer, excellent in slipperiness, and capable, because of the biomass constituent ratio of the entire film being as high as at least 45%, of alleviating environmental loads, and to provide a packaging material and a packaging bag using the same.MEANS FOR SOLVING THE PROBLEM: There is provided a sealant film being a sealant film used while being laminated on a substrate layer, specifically, a multilayer laminate film comprising one or more layers consisting of a polyethylene-based resin derived from petroleum and one or more layers consisting of a polyethylene-based resin derived from a plant, where the outermost surface layer forming the substrate layer laminating surface is a layer consisting of the polyethylene-based resin derived from petroleum and the biomass constituent ratio of the entire sealant film is 45-80%.SELECTED DRAWING: Figure 1 |
