ABSTRACT:
The invention relates to a production process for a foam wound dressing having an external germ barrier, more particularly a film layer, and also to a wound dressing thus obtained, having, where appropriate, a pressure-sensitive adhesive layer. In the process according to the invention the germ barrier is produced by means of extrusion directly on the foam base. This results in a more reliable bond between foam layer and germ barrier, without detriment to the absorptiveness of the foam for wound exudate. The process presented is simple and cost-effective, and all of the requirements from the medical sector (e.g. absence of solvent) can be met.
