A synthetic tubular sausage casing for processing dry sausages is prepared by impregnating or coating a reinforcing paper, preferably a saturating tissue, with a solution or dispersion of a water-soluble or dispersible protein, having a molecular weight above about 10,000 and an isoelectric point in the range from pH 2 to pH 6. The solution or dispersion is of a concentration such that the protein is impregnated in or coated on the paper at a concentration of about 0.1 percent -6.0 percent based on dry weight of the paper. The paper coated or impregnated with protein is cross linked by reaction with a nontoxic cross-linking agent (nontoxic in the resulting product). The coated or impregnated paper is then formed into a tubular casing and impregnated with viscose or other suitable material which is hardened or regenerated in and upon the protein saturated or coated paper reinforcement.
