Abstract
A tubular food casing comprising a film which has been bent to form a tubing, the longitudinal edges of which are joined to one another by means of an adhesive tape, which forms a glued seam. The adhesive tape comprises a plurality of incisions, ending in the area of the glued seam, which extend transversely to its longitudinal direction. In the area of the incision ends, the adhesive tape is firmly bonded to the film. The bond strength between the adhesive tape and the film is greater than the tear resistance of the film.
