Abstract

The present invention relates to a method for forming at least one imprinted region in a solid cellulose foam, the method comprising the steps of: a) providing a solid cellulose foam; b) applying moisture at least to a region of the solid cellulose foam where the at least one imprinted region is to be formed, so as to provide the solid cellulose foam with at least one moistened region; c) pressing at least one forming tool into the at least one moistened region on the solid cellulose foam such that at least one imprinted region is formed in the solid cellulose foam; and d) drying the solid cellulose foam.
