摘要:
The invention relates to laminate segments equipped or coated with an adhesive matrix, particularly transdermal therapeutic systems having formulations strongly tending to leak adhesive. The inventive laminate segments include a matrix, with or without a back layer, a protective layer on the adhesive side of the matrix, provided with a cut as a peel-off aid, and a cover film partially coated with adhesive, applied to the protective film, which overlaps the cut in the protective film using the adhesive-free part thereof. The cover film prevents a leakage of the adhesive through the cut, and therefore a gluing together of the laminate segments to the packaging material thereof, without having an adverse effect on the function of the cut as a peel-off aid. Such laminate segments can be produced without the use of any intermediate carriers.
