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.
Claims20
A tubular food casing comprising a film bent to form a tubing and an adhesive tape extending in the longitudinal direction of said tubing, said adhesive tape joining the edges of said film which extend in the longitudinal direction of said tubing such that a glued seam is formed between said adhesive tape and said edges, wherein said adhesive tape comprises a plurality of incisions extending transversely from at least one longitudinal edge of said tape, wherein each of said incisions terminates at a point located within said glued seam, and wherein the bond strength between said adhesive tape and said film is greater than the tear resistance of said film.
