    摘要: Disclosed is a tubular packaging material for sausage casings, comprising a carrier tubing comprised of cellulose hydrate and containing in its wall from about 5 to 12% by weight of water and from about 18 to 28% by weight of a plasticizer; and a coating on the inside and on the outside of the carrier tubing of a water-insoluble heat-cured synthetic condensation product wherein the carrier tubing is characterized by a swelling value in the range from about 80 to 120%, and the tubular packaging material, after soaking in water at a temperature between about 40.degree. to 50.degree. C. for a period of about 30 minutes and subsequent cooling to about room temperature, is characterized by dimensions in the wet state which are 2 to 6% greater than those before the soaking in water. Also disclosed are methods for preparing the packaging material.

    摘要: Disclosed is a tubular packaging material to produce a sausage casing comprising a carrier tubing comprised of hydrate and containing in its wall from about 5 to 12% by weight of water and from about 18 to 28% by weight of a plasticizer; an anchoring layer on the outside of the carrier tubing of a water-insoluble heat-cured synthetic condensation product; a film coating on the outside of the carrier tubing which is substantially impermeable to water and water vapor and which comprises a copolymer of vinylidene chloride; and a water-permeable adhesion-promoting layer on the inside surface of the carrier tubing, comprising a water-insoluble, heat-cured condensation product. The carrier tubing is characterized by a swelling value in the range from about 80 to 120%, and the tubular packaging, after soaking in water at a temperature between about 40.degree. to 50.degree. C. for a period of about 30 minutes and subsequent cooling to about room temperature, is characterized by dimensions in the wet state which are about 2 to 6% greater than those before the soaking in water, and wherein the tubular packaging, after simmering or boiling at a temperature of about 85.degree. C. for about 30 minutes and then cooling to room temperature, is characterized by dimensions in the wet state which are about 1 to 3% smaller than the wet state dimensions of the tubular packaging material which has only been subjected to said soaking in water. Also disclosed are methods for preparing the tubular packaging material.
