Zusammenfassung:	To provide a sealant film capable of improving low temperature seal ability and rigidity.SOLUTION: There is provided a sealant film formed of a polyethylene resin composition, the sealant film at least comprises: a first layer; and a second layer. One surface layer of the sealant film is the first layer, the first layer includes an ethylene-α olefin copolymer as a main component, and the second layer includes polyethylene as a main component. A melting point of the first layer is 112°C or lower, and a melting point of the second layer is 114°C or greater in the sealant film.SELECTED DRAWING: Figure 1 【課題】低温シール性及び剛性が向上されたシーラントフィルムの提供。【解決手段】本発明は、ポリエチレン樹脂組成物から構成されるシーラントフィルムであって、第１層と、第２層とを少なくとも備え、前記シーラントフィルムの一方の表面層が、前記第１層であり、前記第１層は、エチレン－αオレフィン共重合体を主成分として含み、前記第２層は、ポリエチレンを主成分として含み、前記第１層の融点が、１１２℃以下であり、前記第２層の融点が、１１４℃以上である、シーラントフィルムである。【選択図】図１
