A resealable packaging system, providing a multiple reseal capability. A strip of pressure sensitive adhesive is applied over a first area of a substrate. Then a strip of cold seal adhesive is layered over the strip of pressure sensitive adhesive. A strip of cold seal adhesive is then applied to a second area of the substrate, or to another substrate, whether of the same or a different type. The materials are chosen so that, when the substrate is aligned and the strips of cold seal adhesive bonded together, the bond formed between the strips of cold seal adhesive, and the bond between the pressure sensitive adhesive and the cold seal adhesive, and the bond between the cold seal adhesive and the substrate, are stronger than the bond between the substrate and the pressure sensitive adhesive. Thus, when the two areas of substrate, now bonded together by the cold seal adhesive, are peeled apart, the pressure sensitive adhesive remains with the cold seal adhesive and is exposed. A multiple reseal capability is thereby provided, with the surface of one substrate thus substantially freed of adhesive to facilitate removal and repackaging of the package contents.

[ We claim:] [1.] A resealable packaging material, comprising:a substrate;a strip of pressure sensitive adhesive applied over a first area of said substrate;a first strip of cold seal adhesive applied over said layer of pressure sensitive adhesive; anda second strip of cold seal adhesive applied over a second area of said substrate;such that, when said strips of cold seal adhesive are aligned to bond them together, the bond formed between them, and the bond between the cold seal adhesive and the pressure sensitive adhesive, and the bond between the cold seal and the second area of said substrate, are all stronger than the bond between the first area of substrate and the pressure sensitive adhesive, resulting in the entire removal of the pressure sensitive adhesive from the first area of substrate when the two areas of substrate are peeled apart, thereby providing a multiple reseal capability.
