Abstract
The invention concerns flat or tubular cellulose-based foodstuff casings which are prepared by extruding ('spinning') cellulose dissolved in N-methyl-morpholine-N-oxide by means of a nozzle with an annular gap. After extrusion, the casings are stretched transversely in ambient air by blow moulding, and are then treated with an NMMO-containing aqueous spinning bath. The tubular casings are particularly suitable as sausage casings. Cut open, they can also be used as flat foils.
