Bag combination made of weldable foil

摘要

The interconnected bags (2,3) are made of a weldable foil, bounded by a limit seam, and are of different length. Typically the bags are sleeve-type (14,15). They can have their edges sealed. The limit seam (5) may be of a peel-type (5a). Pref. the bags contain different prods., in a given mass and vol. ratio. The surface of the limit seam is less than the sum of weld seams (6,7) parallel to the separating seam. The limit seam may contain a perforation parallel to its boundary lines.
