に低下することがある。In the manufacturing process of a multilayer film, a molten resin layer is sandwiched between a main film layer and a release film layer and rapidly cooled while being pressed. In the use stage sealed in the container in the state of, the release film layer causes unexpected delamination from the main film layer, or the content of the container cannot penetrate the release film layer after the main film layer is impregnated. It may remain in the molten resin layer, and this may form a liquid pool at an unexpected delamination portion of the release film layer, further lowering the adhesive force of the molten resin layer.

に低下するものと考えられる。According to the inventor's inference, when the molten resin layer is rapidly cooled between the main film layer and the release film layer during the manufacturing process of the multilayer film and is crushed in a high viscosity state while solidifying, it remains in the molten resin layer. It is considered that stress remains. Therefore, at the use stage when this multilayer film is sealed in a container with the release film layer on the outer surface side,
When the contents of the container impregnate the main film layer and the molten resin layer swells, the residual stress of the molten resin layer is released and the molten resin layer is deformed. It is considered that the adhesive force of the molten resin layer varies at various places, and the release film layer causes unexpected delamination from the main film layer. When the release film layer includes a gas barrier layer, the content of the container does not permeate the release film layer after impregnating the main film layer and remains in the molten resin layer, which causes unexpected release of the release film layer. It is considered that the portion becomes a liquid pool and the adhesive force of the molten resin layer is further reduced.
