ABSTRACT:
Described is a pack for liquids which at least partially comprises walls of plastics-coated paper, in particular side walls of a tubular configuration having a longitudinal sealing seam and a bottom having a transverse sealing seam, wherein the longitudinal sealing seam extends within overlapping edge portions (4, 5) and the cut edge (11) of the edge (5) which is in the interior of the pack is covered by a plastics strip (7) as edge protection.
In order, in spite of overlapping edge portions, (4, 5), to ensure that the pack is satisfactorily liquid-tight, with the capacity to carry tensile forces, with at the same time the edge protection effect, it is provided in accordance with the invention for the pack that the plastics strip (7) as the edge protection means is laid over in a U-shaped configuration in cross-section around the cut edge (11) of the inner edge portion (5) and is sealed (at 30) onto both surfaces of the edge portion (5).
