PROBLEM TO BE SOLVED: To provide a laminate film and a packaging bag having similar level of heat sealability to that of a sealant using conventional polyethylene resin and harder to permeate and adsorb active ingredients than the conventional polyethylene sealant under normal temperature environment.SOLUTION: In a laminate film having a plurality of layers containing a substrate and a sealant layer which is one side of outermost surface of the laminate film, the sealant layer consists of a resin composition mainly containing acid-modified polyethylene (A) and obtained by melting and mixing with the ethylene-vinyl alcohol copolymer (B), and has a percentage of a vinyl alcohol unit of the ethylene-vinyl alcohol copolymer (B) in a range of 0.1 to 11.0 wt.% of the resin composition.SELECTED DRAWING: None |
