  • a film thickness of less than 15 microns, preferably less than 10 microns and more preferably less than 8 microns can be used.
  • Such a foil strip can not only be arranged in the front part, but in another embodiment in the front part and back part, in particular on both sides, as described above for the front part, ie surrounded above and below by paper or paper composite material and preferably over the entire bag width.
  • a particular stability and increase in the bag volume of the lower closed end is e.g. achieved when the back part is continued over the lower closed end to a lower portion of the front part, wherein the lower closed end is formed as a W-fold.
  • the W-fold forming part of the back part of paper or paper composite material or film may be formed, in particular depending on which material has the rear part in this area.
  • the W-folding causes the bottom area of the single bag can enlarge by picking goods and can continue to form a floor.
  • At least the lower part of the front part is also formed of paper, since this part is integral with the back part.
  • the back part and a lower portion of the front part of a paper or paper composite material are formed and the lower closed end is formed as a W-fold, wherein the back part and in the W-fold continued material of the front part and / or the front part and continued in the W-fold material of the back portion in the region of the W-fold, in particular in a lower outer leg tip of W-fold interconnected, in particular glued.
  • Back part and front part can here each be made of the same material (paper, paper composite material or film) or of different material.
  • a W-folding of the bottom region of the lower end generally means that the lower end in the folded state comprises at least 4 superimposed material layers which have a course of folding at precisely 4 material layers, which correspond to the line of the letter W. For more than 4 layers, however, the fold always comprises at least 4 layers that correspond to this folding process.
  • An embodiment may provide that both the front part and the back part in the bottom area are continued in the direction of the respective opposite part and each having a Z-fold, wherein both Z-folds overlap and glued to a W-fold.
  • the invention can also provide that in a respective single bag, the lateral opposite edge areas are connected to each other at the lower closed end to the lower leg tips of the W-fold.
  • a development may provide that in each individual bag, the front part has a lower portion which is formed of a paper or paper composite material and adjacent to the W-fold or passes into this and having a central region which is formed of a transparent film and a upper portion formed of a paper or paper composite material.
  • the embodiment offers the possibility to form both the lower area loaded by the weight of the goods as well as an upper area on a firmer paper or paper composite material, yet to ensure a view of the goods in the middle area.
