Abstract
A tubular food casing based on regenerated cellulose, which casing may be fiber-reinforced, is coated on its inner surface with a copolymer which includes 50 to 84% by weight of vinylidene chloride units, 2 to 20% by weight of acrylonitrile units, 1 to 10% by weight of acrylic acid units, and 1 to 47% by weight of (C.sub.1 -C.sub.18)alkyl (meth)acrylate units. The casing has high water vapor barrier and oxygen barrier characteristics. The shirring folds and lay-flat edges which result during the production and processing of the casing remain undamaged over long storage periods. The inner coating, in addition, shows no hot-water haze on simmering. The casing is particularly suitable as an artificial sausage casing.
