Abstract The invention provides 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, and a cut edge which is in the interior of the pack is covered by a plastics strip as edge protection. In order to ensure that the pack is satisfactorily liquid-tight, in spite of overlapping edge portions, with the capacity to carry tensile forces, while ensuring at the same time the edge protection effect, the plastics strip serving as the edge protection means is laid over in a U-shaped configuration in cross-section around the cut edge of the inner edge portion and is sealed onto both surfaces of the edge portion.
