Abstract
Disclosed is a tubular casing consisting of a cellulose web or of a fiber-reinforced cellulose web, which is curved to form a tube and the longitudinal edge regions of which are bonded by an adhesive. On the inside and/or outside of the tubular casing, there is optionally a smoke-permeable adhesion-promoting layer, in particular a layer of a heat-cured cationic resin. The smoke-permeable adhesive layer contains a condensation product, cured at room temperature, of a polyamide-polyamine, an aliphatic polyamine or a polyamide with bifunctional halohydrins or derivatives thereof, such as epichlorohydrin. Optionally, the tubular casing is shirred, preferably with helical displacement of the seam zone. Also disclosed are processes for manufacturing the tubular casing and for using it as a packaging wrap for foodstuffs, in particular as an artificial sausage casing which can be smoked.
