Abstract (en)
[origin: WO2009095148A1] The invention relates to a protective or process film, produced of a thermoplastic material for use in the production of laminates of medical technology and to a laminate which comprises an adhesive-containing transdermal therapeutic system and a protective or process film adhering to the adhesive of the transdermal therapeutic system with a surface. The protective or process film comprises at least one surface that has a plurality of recesses and/or a plurality of non-recessed portions. The distance of two adjacent recesses and/or the distance of two adjacent non-recessed portions is less than five times the film thickness. The depth of the recesses is not less than 1.2 nanometer and not more than 95% of the film thickness. The film according to the invention effectively prevents the adhesive from sticking to the protective or process film.
