ABSTRACT:
A new bonding agent for fibrous substrates used to reinforce food casing is formulated by dissolving cellulose carbamate and an alkaline curing resin in a dilute caustic solution in such a manner that the ratio of carbamate to resin is greater than 1:1 by weight. The preferred resin is a polymeric reaction product of epichlorohydrin and a polyamide. The bonded substrate contains up to 10% by weight of the bonding agent and exhibits a porosity that is not significantly less than that of the base web and a caustic tensile strength greater than 300 grams per 25 millimeters. Casings made from the substrate can use the casing films employed heretofore or a carbamate-resin film formulation.
