Abstract: A food casing having an internal surface coating of a dried aqueous emulsion including at least one polyglyceryl ester. The polyglyceryl ester in the coating covers the internal surface of the food casing in an amount of from about 200 to about 1200 mg per square meter. The polyglyceryl ester may be almost any polyglyceryl ester having from about 1 to about 4 ester groups formed with carboxylic acids having from about 6 to about 18 carbon atoms. The polyglyceryl ester may for example be selected from triglyceryltetraoleate and triglycerylmonooleate. The food casing has superior meat release characteristics in certain applications.

Abstract: A clipping device is provided for closing stuffed food casing with a clip and an apparatus is provided for causing a taped, holding string loops, to be directed toward the clipping device for closing an end of the food casing so that a string loop is transferred directly from the tape into an entry into a channel in the clipping device. The clip draws the loop to the casing and holds the loop to the food casing. The stuffing apparatus preferably also includes a novel readily cleanable food flow cut-off valve. A punch and clip anvil is provided to apply clips bent around the casing in essentially mirror image helixes. An extending and retracting conveyor is provided to remove stuffed food product from the vicinity of the clipping device after stuffed food casing is closed.

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: Regenerated cellulose food packaging film, including fibrous food casings which has modified cling properties for packaging sausage products. The cellulosic food casings have a fibrous reinforcement impregnated with regenerated cellulose composition which contains from about 0.01 to 2.5 weight percent of admixture of a viscose solution and a food grade cationic resin adhering agent and from about 0.001 to 2.5 weight percent of a protein. The film is prepared by impregnating a tubular fiber reinforcement with a viscose composition containing the resin and protein. The impregnating composition is applied in a single step by injecting the resin and protein into the viscose solution before being extruded into the fibrous web. This assures both even distribution of the polymeric adhering agent and protein in the web, as well as maintenance of a constant level of polymer and protein being applied during the coating process.
