  • both the inside of the outer layer as well each have paper on the outside of the inner layer can or can consist of paper ensures that when forming a longitudinal seam of the bag and / or in the formation of the bottom of the Bag not a direct concern of a paper having side of a layer of the bag on a with plastic coated side of a layer of Bag is done.
  • Block bottom bags or block bottom bags or Buchitzlessnesslessnessn is next to the longitudinal seams especially the formation of the soil, in particular the connection of the two bottom plates using Adhesive, with considerable problems been.
  • Adhesive Adhesive progress in this regard
  • the inner layer of the outer Bottom bracket according to a particularly inventive Further training of the present bag at least a recess that at least partially with the recess in the outer layer of the inner Bottom bracket covers when the outer bottom bracket and the inner bottom flap to form the bottom are laid on top of each other.
  • both the inside the outer layer as well as the outside of the inner layer can each have paper or even made of paper can exist, so that the provided in between Gluing in the form of an adhesive layer its full Can have an effect, making a convincing Stabilization of the state of the art vulnerable bottom area of the bag.
  • the bags are according to the present invention often two layers, that is, with an outer layer and with an inner layer executed.
  • Special applications where the Pouch to be transported is something special high weight or a particularly high Moisture content, but can Require bags with three or more layers.
  • the Liner has at least one recess that yourself at least partially, preferably entirely of the recess in the outer layer.
  • the Recess in the intermediate layer at least partially, preferably entirely with the recess in the Inner layer covers.
  • the recesses in principle, a multitude of possible forms are conceivable, these forms differ according to the intended use the type of adhesive application and according to Available space.
  • at least one of the Recesses of round, oval, elliptical, square, rectangular and / or triangular Shape In preferably at least one of the Recesses of round, oval, elliptical, square, rectangular and / or triangular Shape.
  • At least one floor glue is used Gluing the bottom flaps provided. Independently of these or in addition to this can be found in the area of at least one punch a second floor glue be provided.
