Beschreibung
Zusammenfassung:	A multilayered film which is formed using a solventless adhesive, can obviate wetting deficiency even when the film is manufactured by applying the solventless adhesive to a film by coating at a high speed, exhibits the excellent laminate strength and the excellent impact resistance after a liquid content is filled into a packaging container and exhibits excellent environment friendliness, a method of manufacturing the multilayered film, and a packaging container which uses the multilayered film are provided. In the multilayered film which is formed by laminating at least an inner-layer film, an adhesive layer and an outer-layer film in order, the adhesive layer is formed of a solventless adhesive which contains apolyester-based main agent and a curing agent made of aliphatic isocyanate and alicyclic isocyanate.
