Abstract

Backing materials which have been given a self-adhesive treatment on at least one side, characterized in that the self-adhesive composition is a pressure-sensitive hotmelt adhesive composition which at a frequency of 0.1 rad/s has a dynamic-complex glass transition temperature of less than −3° C., preferably from −6° C. to −30° C. and, with particular preference, from −9° C. to −25° C., and their use, in particular, for producing medical products such as plasters, bandages or dressings.
