Patent ID: 8783950

Claim:
A packaging body which houses contents in a sealable manner comprising: a film made of resin (a resin-made film), and an opening part formed in the resin-made film for taking the contents out, wherein the resin-made film comprises an outer layer, an inner layer, and an adhesive layer in the middle thereof formed by applying an adhesive onto the outer layer or the inner layer so as to form predetermined patterns or combination of the predetermined patterns with an adhesive part where said adhesive is continuously applied and a non-adhesive part where said adhesive is discontinuously applied or not applied, such that a resealing part is formed where said adhesive is applied to the outer or inner layer, wherein the predetermined patterns comprise: a first adhesive part comprising a first pattern of adhesive; a second adhesive part comprising a second pattern of adhesive, wherein said second pattern comprises a different ratio of adhesive covering to non-adhesive covering and/or a different orientation of adhesive strength than said first adhesive part, such that the first adhesive part and the second adhesive part form areas of different adhesive strengths within said resealing part; and a non-adhesive part where adhesive is not applied between said first and second adhesive parts, wherein the first pattern and the second pattern do not overlap with each other when the outer layer is re-sealed, and the predetermined patterns are to provide a desired strength of adhesion and peeling off, whereby the opening part formed in said inner layer is accessible by peeling said outer layer with said non-adhesive part serving as a base point, and is re-sealed by re-adhering said outer layer.
