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. The degree of cling/adherence of the casing to meat contained in the film is more uniform over the entire circumference of the tubular casing and is almost moisture independent.
A tubular cellulosic film meat casing, which comprises a tubular fibrous reinforcement impregnated with a viscose coating composition containing cellulose, wherein said composition, prior to being impregnated into said reinforcement, comprises an admixture of a viscose solution, a food grade cationic resin adhering agent and a protein for imparting to said film, cling properties for a meat product packaged within such film, said resin being present in an amount of from about 0.01 to about 2.5 percent by weight of cellulose and said protein being present in an amount of from about 0.001 to about 2.5 percent by weight of cellulose, a weight ratio of resin to protein being between 100:1 and 1:1 said tubular film having a cling force to encased meat product under both wet and dry conditions of between 350 g/4 cm and 800 g/4 cm, said cling force, under both wet and dry conditions, being sufficient to hang said food casing when stuffed with meat, by an end and weak enough to permit the food casing to be removed from encased meat product without damaging the surface of the meat product.
