  • a packaging bag having the features described above, which in addition to an outer layer of paper has an inner layer of a sealable plastic film, wherein the plastic film is provided with a plurality of vents.
  • the air displaced in the lower region through the air passage openings of the inner layer and formed between the inner layer and the outer layer areas the bag at the head-side filling opening leave. Due to the perforation of the inner layer and the formation of the outer layer of paper, a comparatively high gas exchange is possible even after the bag has been closed.
  • the invention has for its object to provide a packaging bag for powdery product, which allows an overall improved shelf life of the contents.
  • the packaging bag should be used as a building material packaging bag for cementitious construction chemical products.
  • the object is achieved in that the outer layer is formed of a plastic film and that on the outer layer for permanent venting of the packaging bag after its closure a secondary vent is provided, which allows a slow gas outlet.
  • the outer layer of a plastic film provides improved protection against moisture and in particular also represents a diffusion barrier. Therefore, during storage only a controlled gas exchange via the secondary vent, so that the entry of atmospheric oxygen into the bag can be greatly reduced.
  • the invention is based on the finding that the tightness of the formed as a plastic film outer layer is much higher compared to an outer layer of paper, wherein the secondary vent can be made just so that just a sufficient ventilation of the packaging bag is guaranteed.
  • the resistance of Chromatreduzierem that are added to the cementitious building chemical product to avoid skin diseases during use can be significantly increased.
  • the maximum storage time can be significantly increased in the use of the packaging bag according to the invention and at the same addition amount of chromate reducers. So can be achieved with a correspondingly dense configuration of the packaging bag, that the legally prescribed limit value of water-soluble chromate of currently 2 ppm is exceeded at the earliest after 12 months, preferably after at least 18 months.
  • the perforation of the inner layer formed from a plastic film can be produced for example by a needling, wherein the puncture direction is taken into account.
  • the inner layer can be arranged such that the elevations are arranged in the direction of the outer layers or in the direction of the bag interior.
  • the elevations serve as spacers, so that in the areas in which the inner layer and the outer layer are not connected to each other, a distance from the outer layer is generated, which promotes a particularly rapid primary ventilation.
  • the protrusions are arranged in the direction of the bag interior, this leads to an increase in the roughness.
  • the inner layer of plastic
  • the friction between the inside facing the bag interior and the inflowing filling material is increased, so that a kind of rolling motion or turbulence arises at the boundary layer .

  • the at least one venting channel can be optimally integrated into the associated longitudinal edge. In particular, the stability of the longitudinal edge and the visual appearance are virtually unaffected.
  • the vent channel integrated in a section of the longitudinal edge is additionally protected in a particularly advantageous manner against kinking or damage.
  • a plurality of longitudinally spaced and mutually independent ventilation channels can be formed at the longitudinal edges of the packaging bag formed as folded edges.
  • the outer layer of the packaging bag is formed from a plastic film, there is also an improved strength, so that when handling the building material packaging bag, for example when throwing or dropping, the risk of bursting is reduced. Due to the tightness of the packaging bag according to the invention can also be prevented that this heavily contaminated on its outer side, which is particularly suitable for products that are intended for retail in the With regard to product presentation and removal by the consumer. Due to the increased strength of the packaging bag and the risk of unintentional opening is significantly reduced.
  • a handle can also be provided in the packaging bag according to the invention to facilitate transport. The handle can be formed without restriction from the material of the inner and the outer layer, for example by a punched-out, or by a separately attached grip band.
  • tear-open in the form of lines of weakness can be provided.
  • a reclosure for example a zipper or slider closure, so that after removal of a subset of the contents, the portion remaining in the packaging bag remains storable for a long period of time.
  • the ingress of moisture and ambient air can be prevented to a certain extent even after initial opening, so that on the one hand clumping and, on the other hand, rapid decomposition of additives, for example chromate reduction, can be avoided.
