  • Patent number: 5071260
    Abstract: A profiled bottom bag made of paper, plastic foil or a similar foldable material has at least one profiled end provided at its outside with a handle-forming strip whose length is essentially that of the profiled end. A handle section extends between connecting areas and, in contrast to the connecting areas, is narrower. The handle-forming strip forms part of a prefabricated cut section encompassing a separating strip which extends under the handle section of the handle-forming strip without being bonded thereto, whose width corresponds to that of the handle-forming strip in the end-connecting areas of the strip, whose length, measured in the longitudinal direction of the profiled end, but in contrast to the length of the handle-forming strip, is shorter up to the narrow connecting areas on both sides of the handle section of the handle-forming strip. The separating strip and the handle-forming strip are bonded together.
