Abstract
Abstract Disclosed is a tubular sausage casing of a cellulose material having a longitudinal seam region whereat is located a smoke-permeable adhesive-containing layer of a substantially water-insoluble cationic resin which is a condensation product of a polyamide-polyamine, an aliphatic polyamine or polyamide with bifunctional halohydrin or derivative thereof. The casing also includes a coating on its inside surface of an oily emulsion having a first component comprising a water-soluble cellulose ether or a water-soluble modified starch, and a second component comprising an oil and an emulsifier. Also disclosed is a process for producing this casing and sausage products made therefrom.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
170 words
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.
Claim 2
Dependent Claim
170 words
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.
