ABSTRACT:
The present invention sets forth a profile sealing strip having a lateral flange and a sealant layer. The lateral flange includes a first section, a second section, and a middle section being disposed between and connected to the first and second sections. The closure portion has a base connected to the middle sections and protruding beyond the upper surfaces of the first and second sections. The structure of the sealant layer and the lateral flange are modified so as to reduce the curl experienced during the cooling process after the lateral flange and the sealant layer are attached to one another.
