Abstract: The present invention discloses a method and process to laminate packaging substrates using an adhesive tape. The tape has a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature and both of which are alternatively coated on at least one surface of the tape. The method consists of laminating this aforementioned tape to a packaging substrate by following the process of: placing this tape in or on a laminating machine over the packaging substrate, heating the tape at least to the second temperature while making contact with the packaging substrate, cooling the packaging laminate until the second heat activated adhesive is set and cutting a predetermined portion of the packaging laminate before a second adhesive occurs between the tape and the packaging laminate.

Abstract: An adhesive packaging system, such as a tape or a string, and laminating methods are disclosed. The system comprises a core structure and an adhesive layer coated at least on one surface defined by the core structure. The adhesive layer comprises at least two different heat-activated adhesive materials in alternative sequences over the surface of the core structure, the heat-activated adhesive materials being activated at different temperatures. As the tapes are processed in the laminating machines, some of the adhesives will be heat activated with enough operating range that the tapes will have the proper adhesion to the substrate in any operating conditions, and some of the adhesives will set at the exit of the laminating machines also at any operating conditions of the laminating machines. Hence the tapes will have a much larger operating envelope under a very large range of operating conditions in the laminating machines.
