Food Casings With Modified Adhesion And Release Properties And Methods Of Manufacture

A method for the manufacture of a fibrous reinforced food casing comprising a fibrous reinforced layer located between an inside layer and an outer layer, said method comprising the following steps:

• a) a peeling agent comprising one or more polyalkylene glycols and any mixtures thereof is injected in an inside viscose stream or outside viscose stream or both;
• b) an inside file adhesion promoter comprising one or more protein coagulants, proteins, glyoxals, gluteraldehyde, caseins, gelatins, wet strengths resins and any mixtures thereof is injected in an inside viscose stream;
• c) a fibrous web, preferably a tubular fibrous web is impregnated with viscose by applying to the inside of the fibrous web inside viscose stream;
• and applying to the inside viscose stream;
• and applying to the outside of the fibrous web the outside viscose stream;
• and
• d) the method is continued with conventional coagulation, regeneration, washing and drying steps.
