摘要： A resealable packaging system is disclosed. A strip of pressure sensitive adhesive (22) is applied to a substrate, followed by a strip of cold seal adhesive being layered over the adhesive. A strip of cold seal adhesive (26) is then applied to a second area of the substrate (12), or to a different substrate. The materials are chosen so when the strips of cold seal adhesive are bonded together the bond formed between the strips of cold seal adhesive, between the pressure sensive adhesive and the cold seal adhesive, and between the cold seal adhesive and substrate are each stronger than the bond between the substrate and the pressure sensitive adhesive. Thus, when the two areas of substrate are peeled apart, the pressure sensitive adhesive remains with the cold seal adhesive and is exposed, with a multiple reseal capability thereby also being provide.
