Definitions

  • Such a packaging bag is known from GB-A 2 161 454, which consists of thermoplastic film webs which are connected on both sides and at the bottom by welds. Opposite reinforcement tabs are connected to the two film webs in the area of the upper opening. Each of the reinforcement tabs is provided with a handle recess together with the film webs.
  • One of the packaging tabs is extended and equipped with a wicket perforation. A line of weakness is attached below the wicket perforation and finally with the upper edge of the film web and the reinforcement flap.
  • a film bag which is used to be stacked on a wicket and to be able to be unfolded during filling.
  • a wicket perforation and a corresponding cutout are punched into the paper or plastic film web at a repeat distance and at the same height before folding.
  • the position of a cutout in relation to the adjacent wicket perforations lying at the same height is chosen such that the cutout in the film tube lies above the wicket perforation and exposes it.
  • the wicket area and the protruding film tube are cut off by a cut-off weld cut.
  • “Foil tube” can be understood to mean both an originally tubular extruded tube and a double web which is connected at the edge to form a tube.
  • a disadvantage of the known packaging bag is that a relatively large amount of packaging material is generated as waste. This can be used again in a recycling process; the losses are still considerable.
  • the task for a packaging bag according to the invention is to avoid the losses that occur when removing the film surface with the wicket perforation, to avoid them entirely.
  • the bag design according to the invention is therefore based on a bag in which the film tube material itself is not provided with a wicket perforation, but rather an additional part is glued on, welded on or fastened in some other way, the additional part being a "flag "is designated. It can also be waste sections that are prepared in a corresponding manner.
  • the “flag” can preferably be rectangular, but can also be polygonal in another way, for example rhombic or triangular.
  • the tube preferably has a cut-off edge and the flag is designed as a rectangular strip which is arranged with its long side parallel to the cut-off edge of the bag.
  • the wicket perforations preferably two, can be made in a single tab; however, it is also possible for a flag, each having a perforation, to be arranged on the flat side of the bag in accordance with the number of wicket perforations.
  • the flags are connected to the outside of the bag and, starting from an outer edge, the flags are provided with at least one slot which extends over part of the distance between the outer edge and wicket perforation in the direction of the wicket perforation.
  • the bag 1 made from a film tube consists of paper or plastic suitable for packaging purposes, possibly also composite materials. In principle, all sheet-like materials that are used in the packaging industry can be used.
  • the bag 1 is closed at its head end with the aid of a transverse weld seam 2.
  • the side walls are turned slightly inwards by an inner fold 3. Its lower end 4 is open. In the present case, the state is drawn just before filling.
  • the bag is inflated by an air stream before filling.
  • a rectangular flag 10 provided with a wicket perforation 6, 7 is attached to one of the flat sides 5 in the region of the lower end 4.
  • the flag 10 is with their longitudinal side parallel to the cut edge 11 of the bag 1.
  • the flag 10 consists of a plastic film material which usually corresponds to or is similar to the material of the bag 1, but does not need to be printed or otherwise processed. For example, it can also be cut from cut "waste" strips.
  • the wicket perforations 6, 7 have the usual spacing and diameter that are compatible with existing wicket mandrels.
  • the flag 10 is connected to the bag outside 5 via a weld 9.
  • the weld seam is placed as close as possible to the edge 11 of the open end in order to accommodate the part of the flag that gets stuck there when the bottom area is later folded in, ie. H. insert and weld in the floor area so that the floor area is additionally reinforced.
  • the flag 10 can also have a predetermined tear line 12, so that the machine-filled bags can be torn off the wicket in a simple manner and avoiding all damage, part of the flag remaining on the wicket thorns.
  • FIG. 2 shows an embodiment in which the lower end 4 of the bag is provided with two wicket flags 20 and 21.
  • the wicket flags 20 and 21 are glued or heat-sealed to the outside of the bag 1 (only partially shown).
  • the wicket flags 20 and 21 have a rectangular shape; their area is greatly reduced compared to the wicket flag 10 according to FIG. 1.
  • Each a wicket perforation 16, 17 is punched approximately in the middle of the freely projecting part of the wicket flag 20 or 21.
  • These slots 18 and 19 facilitate the tearing of the wicket flags or the bag from the wicket mandrels.
