ABSTRACT:
Methods are provided for producing flexible packages and particularly transdermal medication patches. The method includes the continuous and rapid production of a plurality of such packages while continuously treating one portion of the laminate forming the package by corona discharge in order to modify the surface adhesion properties thereof to provide, simultaneously, a proper seal of a transdermal membrane in the laminate forming the package, while maintaining the desired medication dispensing properties thereof.
