Zusammenfassung:PROBLEM TO BE SOLVED: To provide a laminated film which shows excellence in non-adsorbency and barrier properties against a low molecular weight organic compound, can prevent a change of a content, causes no delamination, has stable sealability, and can be economically produced without adding a catalyst or an additive. SOLUTION: In the laminated film 10 comprising a plurality of a base material 17 and a sealant layer 11, the sealant layer 11 is made by quenching and solidifying a heat-molten film of an isophthalic acid-modified polyethylene terephthalate resin.
