Title:
METHOD AND DEVICE FOR LABELING A TWO-DIMENSIONAL POLYMER ADHESIVE SYSTEM, ESPECIALLY A TRANSDERMAL THERAPEUTIC SYSTEM
Document Type and Number:
WIPO Patent Application WO2000064684
Kind Code:
A3
Abstract:
The invention relates to a method and to a device for labeling a two-dimensional polymer adhesive system, preferably on the adhesive-free side thereof, with information. The inventive method is characterized in that the adhesive system is labeled by using a movable laser beam. The aim of the invention is to carry out the labeling in such a manner that the ingredients contained in the system are not damaged by the heat produced by the laser beam and that the backing layer that is impermeable to the ingredients or steam is not perforated. To this end, the intensity and the penetration depth of the laser beam is adjusted depending on the type of material used in said system in such a manner that the laser beam does not penetrate the material down to a layer of the system that contains the ingredients.
