Abstract
A description is given of a tubular food casing having a glued, permanently elastic longitudinal seam based on a flat fibrous material coated with acrylic, collagen and/or a protein derived therefrom. The seam is generated using a reactive hotmelt glue. The glued seam is resistant to boiling for a long time and also exhibits sufficient stability thereafter. The insert is preferably a textile material, a concolidated nonwoven or spunbonded nonwoven, a woven fabric, loop-forming knitted fabric, laid fabric, loop-drawingly knitted fabric or a fiber paper. It is coated in the flat state. The coated longitudinal strip is cut into strips according to the diameter of the casing to be produced and glued using a PUR hotmelt glue to form the tube. The food casing is preferably used as artificial sausage casing or for wrapping cheese or fish.
