Abstract
Providing a packaging body and a film made of resin (a resin-made film) used therefor that can store the remaining contents even after a part of the contents is taken out, wherein the packaging body is easily openable and closable without providing a zipper, has a storage property equal to that of a body provided with a zipper, and can be manufactured at a low cost.The resin-made film is constructed with at least an outer layer 6, an inner layer 7, and an adhesive layer 8 in the middle thereof formed by applying an adhesive onto the outer layer 6 and/or the inner layer 7; the adhesive is releasable and re-adherable; and at least a part of the adhesive layer 8 is formed by a combination of an adhesive part 8b where said adhesive is continuously applied and a non-adhesive part 8a where said adhesive is discontinuously applied or a non-adhesive part 8c where the adhesive is not applied.
