Method of manufacturing food casings with modified adhesion and release properties

A method for the manufacture of a multilayer tubular fibrous reinforced food casing comprising a tubular fibrous web located between an inside viscose regenerated cellulose layer and an outside viscose regenerated cellulose layer, said method comprising:

• injecting a peeling agent in an outside viscose stream, wherein the peeling agent is a polyethylene glycol homopolymer of ethylene oxide having a molar mass between about 25,000 g/mol and about 40,000 g/mol;
• injecting an adhesion promoter comprising one or more protein coagulants, proteins, glyoxals, gluteraldehyde, caseins, gelatins, wet strength resins, or any mixture thereof in an inside viscose stream;
• and
• impregnating the tubular fibrous web with viscose by applying the inside viscose stream to an inside surface of the fibrous web and applying the outside viscose stream to an outside surface of the fibrous web, such that the amount of the peeling agent in the casing is between about 0.1% by weight and about 30% by weight based on the total dry weight of the viscose regenerated cellulose contained in the casing.
