Easily peelable sausage casing having a glued seam, process for its manufacture, and its use

A sausage casing, comprising:

• a cellulose film curved around the longitudinal axis of said film so that the edges of said film form a seam parallel to the longitudinal axis;
• a smoke-permeable adhesive-containing layer in the region of said film edges consisting essentially of a substantially water-insoluble condensation product of a polyamide-polyamine, an aliphatic polyamine or polyamide with a bifunctional halohydrin or a derivative thereof, said condensation product joining said film edges at said seam;
• and
• a coating on the inside surface of said curved film of an oily emulsion comprising (a) a first component selected from a water-soluble cellulose ether or water-soluble modifed starch, (b) a second component comprising at least one oil selected from the group consisting of a triglyceride mixture of saturated fatty acids with carbon chain lengths of about 4 to 14 carbon atoms, mineral oil, paraffin oil, natural oil and silicone oil, and (c) an emulsifier, said second component being present in an amount from about 15 to 100 times greater than said first component.
