Title:
SMOKE PERMEABLE NON-REINFORCED FILM BASED ON REGENERATED CELLULOSE FOR PRODUCING TUBULAR SAUSAGE CASING EQUIPPED WITHSEAM IN LONGITUDINAL DIRECTION AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPS59224644
Kind Code:
A
Abstract:
Disclosed is a smoke-permeable, nonreinforced film comprising regenerated cellulose, for manufacturing tubular sausage casings which have a seam extending in the direction of their longitudinal axis. The film has a wet tear strength of from about 18 to 30 N/mm2, both in the longitudinal and transverse directions, a degree of orientation in the range from about 1 to 1.2, and a number of alternate bends ranging from about 5,000 to 8,000 in the longitudinal direction, and from about 9,000 to 16,000, in the transverse direction. Also disclosed is a process for producing the film in which viscose is extruded in the form of a web, thereafter precipitated by treating it with a heated casting solution and then regenerated into cellulose hydrate gel. The casting solution used to precipitate the viscose comprises, per liter of solution, at least about 160 g of sulfuric acid and at least about 300 g of sodium sulfate and the molar ratio sulfuric acid/sodium sulfate is in the range from about 0.7 to 0.9. In addition, there is disclosed a sausage product comprising a tubular casing of the type described above.
