Abstract
The invention relates to a process for the treatment, in particular for the roughening, of the surface of hydrated cellulose shaped articles, in which at least one cellulase is allowed to act on the surface and is then inactivated permanently. The tubular films modified in this way are particularly suitable as foodstuff casings, specifically as sausage casings.
