Abstract

Essentially inelastic backing material for medical purposes, characterized in that the backing material has an addition of high-strength fibers, multi-strand yarns, mixed multistrands or filaments having an ultimate tensile stress strength of at least 60 cN/tex, preferably from 80 to 500 cN/tex, the high-strength fibers, multi-strand yarns, mixed multistrands or filaments having a water absorption of less than 10%, preferably less than 5% and, with particular preference, less than 3% and the high-strength fibers, multi-strand yarns, mixed multistrands or threads giving the backing material an ultimate stress strength of at least 50 N/cm, preferably from 60 to 450 N/cm and, with particular preference, from 65 to 250 N/cm, and in that the backing material is coated at least partially on at least one side with a hotmelt adhesive composition.
