Title:
WEB-SHAPED OR TUBULAR PACKAGING FILM AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPS62108048
Kind Code:
A
Abstract:
A web-shaped or tubular packaging film for use in food packaging applications, particularly as a sausage casing, is comprised of a carrier layer based on fiber-reinforced celulose and a closed thermoplastic, sealable resin coating based on copolymers containing vinylidene chloride (VDC) units. To improve the kink resistance, this resin coating is built up from at least two superposed layers, the first resin coating layer adjacent to the carrier layer being composed of a VDC copolymer forming flexible films and the outer, second resin coating layer being composed of a VDC copolymer forming rigid films. The web-shaped film is suitable for the production of tubular packaging casings, in particular sausage casings, with a longitudinal seam.
