Abstract

A tubular casing for foodstuffs, in particular sausages, comprising a web (4) which is curved along its longitudinal axis and having its longitudinal edge regions (1, 2) bonded by a glued seam. The edge regions (1, 2) meet or overlap and are bonded with a strip of film (6). A pressure-sensitive adhesive is used for the bonding. The tubular casing carries an adhesion-promoting layer (5) on the surface adjacent to the adhesive layer (3). Preferably, the strip of film and the edge regions of the web are comprised of a smoke-permeable material, and optionally the pressure-sensitive adhesive layers also have a smoke-permeable structure, such as perforations. The tubular casing can also be shirred.
