Abstract: A tubular food casing of a tubular cellulose film precipitated from a viscose solution having a viscosity of from about 55 to about 90 ball seconds, where the ball has a density of 8 g/cc and a radius of 0.316 centimeters at a drop of 20 centimeters, and where the solution contains at least eight and one-half weight percent of cellulose. The cellulose has a DPv of from about 300 to about 525 and the cellulose film has a dry film thickness of from about 0.015 mm to about 0.040 mm, a dry burst pressure in excess of 40 cm Hg, per 0.01 mm of dry film thickness, and a rewet burst pressure in excess of 5 cm Hg per 0.01 mm of rewet film thickness.

Abstract: A cellulose food casing which can be peeled from food product contained therein without damaging said food product, said food casing having an internal surface composition comprising regenerated viscose containing polyalkylene glycol having a molecular weight of from 300 to 20,000. The invention further includes such food casings in fibrous form wherein only the internal layer of viscose contains polyalkylene glycol and the method for making such casings.
