Definitions

  • the invention relates to a pouch packaging made of a plastic film with a front and back surface connected by gussets and a closed by a bottom seal bottom surface.
  • the pouch packaging is prefabricated as a flat film pouch and sealed after filling in a Beutelbehellstrom by a top seal which connects the front surface with the rear surface and the head end of the gussets with the adjacent front or rear surface.
  • the bag packaging which is also referred to in practice as a stand-up pouch, usually has an unfilled head area in which air is located or the front and back surfaces lie flat against each other. This area is not stabilized by the contents and can therefore be easily buckled by mechanical action. In practice, this frequently results in the head area no longer being visible due to the buckling when the stand-up pouch is on the sales shelf. The visual appearance is impaired and the presentation area is no longer fully utilized.
  • a method is described, can be made with the dimensionally stable packaging container made of a plastic film.
  • the film is coated with a structurally convertible substance and an activator in areas which are to have a higher rigidity after shaping.
  • the coated wall regions are heated or, for example, irradiated with UV light in order to trigger a chemical reaction in the coating material.
  • the coating cures and forms stiff surface areas.
  • the method described is suitable for the production of packages which are preformed before filling with filling material, for example, packaging trays, parallelepipedic packaging for liquids and the like.
  • the film described is not suitable because a subsequent heating or irradiation could damage the contents.
  • the EP 0 362 102 B1 describes a made of a foil blank cuboid packaging for liquids.
  • a reinforcing film is laminated on the inside of the film, which is welded to the film along all longitudinal edges of the packaging container produced from the laminating composite.
  • a relatively thick reinforcing film must be used, which adversely affects both the cost of materials and the weight of the package.
  • the invention has for its object to provide a pouch packaging for bulk material that is so dimensionally stable in one of the contents not filled head area that the head area does not buckle when the stand-up pouch is on the shelf.
  • the object is achieved in that at least in an upper region of the bag packaging, which is not filled by filling after a bag filling, a grid for stiffening the plastic film bag inside the plastic film is attached.
  • the grid stabilizes the head region, it being sufficient if the grid extends from about the maximum level or preferably below about the maximum level starting to the top end of the bag package.
  • Particularly suitable are coarse-meshed grids that can be inserted at low weight Distinguish high moment of resistance.
  • the grid attached to the inside of the bag for stiffening purposes does not affect the external appearance of the bag package.
  • the plastic film from which the pouch packaging is manufactured can consist of a multilayer composite film in a manner known per se, which has a layer of a sealable polymer on the inside of the pouch and a printable layer of a non-sealable polymer on the outside of the pouch.
  • the pouch packaging can be prefabricated as a flat and stackable foil pouch.
  • the gussets are flexible and are not stiffened by measures inside the bag.
  • the front surface and the rear surface are each reinforced by a lattice laminated to the plastic film. Reinforcement may be limited to the top of the front and back surfaces, which are not stabilized by contents after bag filling.
  • the grid is preferably made of plastic and is welded or glued to the plastic film.
  • the attachment of the grid to the inside of the bag can also be done by a cover, which is applied to the inside of the bag on the grid, is directly connected to the plastic film and thereby fixes the grid to the plastic film.
  • the cover is expediently over at the edges of the grid and is connected along the protruding edges with the plastic film.
  • the cover film is further connected in grid openings with the plastic film.
  • pouch packaging consists of a plastic film and has a connected by gussets 1 front and back surface 2, 3 and a closed by a bottom seal bottom surface 4.
  • the pouch packaging is first prefabricated as a flat lying, open-topped foil pouch, which is filled in a bag filling with lumpy or pourable material and then sealed by a top seal 5.
  • the top seal seam 5 extends over the entire width of the bag package and connects the front and back surfaces 2, 3 together and the upper end of the gussets 1 with the respectively adjacent front or back surface 2, 3.
  • the bag package also referred to as a stand-up pouch has an unfilled upper area 6, in which air is located or the front and rear surfaces 2, 3 lie on each other. This area is not stabilized by the contents 7. In practice, there is a risk that this area kinks and is no longer visible when the stand-up pouch is on the shelf, for example.
  • a grid 8 for stiffening the plastic film bag inside the plastic film 9 is attached.
  • the grid 8 is formed coarsely meshed and has a high resistance torque at a low weight on. It is respectively attached to the inside of the bag on the front surface 2 and the rear surface 3 and preferably extends from one point slightly below the maximum level to the top of the bag packaging below the top seal 5.
  • the grid 8 is preferably made of plastic. It is made, for example, from 0.5 to 2 mm thick filaments.
  • the grid 8 is formed coarsely meshed and has, for example, a mesh size between 10 X 10 mm and 40 X 40 mm.
  • the plastic film 9, from which the bag package is made consists of a multilayer composite film having on the inside of the bag a layer 10 of a sealable polymer and on the bag outside a printable layer 11 of a non-sealable polymer.
  • the existing plastic mesh 8 can be welded or glued to the plastic film 9.
  • the attachment by means of a cover 12, which is applied on the inside of the lattice bag.
  • the cover film 12 is directly connected to the plastic film 9 and thereby fixes the grid 8 on the plastic film.
  • the cover film 12 projects beyond the edges of the grid 8 and is connected to the plastic film 9 along the protruding edges 13.
  • the cover film 12 is glued or welded in the grid openings 14 or at least in some grid openings with the plastic film 9.
  • the attachment measures described can be implemented individually or in any combination.
