ABSTRACT OF THE DISCLOSURE Disclosed is a tubular casing of fiber- reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 ar.d an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. The adhesive layer is smoke- permeable and is preferably composed of a material system which sets without a chemical reaction. The film web is produced from viscose, and it is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.
