摘要:
The invention relates to a web-form packaging material which comprises at least one layer, comprising a packaging material surface, of a sealable material, to a packaging unit with a transdermal therapeutic system and with a packaging material of this kind, and also to a process for producing a packaging unit. For this purpose, at least the abovementioned surface of the packaging material has a multiplicity of recesses and/or a multiplicity of non-recessed regions. The distance between two adjacent recesses and/or the distance between two adjacent non-recessed regions is less than five times the packaging material thickness. Moreover, the depth of the recesses is not less than 1.2 nanometers and not more than 95% of the packaging material thickness. With the present invention, the sticking of an adhesive on the inner face of the packaging material is effectively prevented.
