Abstract
A shirr-stable, tubular food casing having a glued, permanently elastic longitudinal seam based on a flat fibrous textile material coated with acrylic, collagen and/or a protein derived therefrom is provided. 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. Exemplary textile materials include a consolidated nonwoven or spunbonded nonwoven, a woven fabric, loop-formingly knitted fabric, laid fabric, loop-drawingly knitted fabric. To form the casing, the textile material is coated in the flat state. The coated textile material is cut into strips according to the diameter of the casing to be produced and glued using a reactive hotmelt glue, such as a PUR hotmelt glue, to form the tube. The food casing is preferably used as artificial sausage casing or for wrapping cheese or fish.
