Packaging bag made of film tube

The innovation relates to a one-sided open packaging bag made of cut film tube, which has a removable film surface with a Wicket Perfosation in the region of its open end.

Such a film bag is described in the non-prepublished patent application P 37 33 367.4 of the applicant. The proposed Verpackungsbeute1 serves to be stacked on a so-called wicket and to be unfolded during filling. For this purpose, a wicket perforation and a corresponding cutout is stamped into the paper or Kunststoffolienbahn before folding each in repeat distance and at the same height. The location of a section to the adjacent, lying at the same height Wicket perforation is * chosen so that the film tube the cutout above the wicket perforation is exposed and this. After filling of said packaging bag the Wlcketbereich and the supernatant film tube is cut by a cut-weld cut.

A disadvantage of the proposed Varpackungsbeutel is felt that a relatively large amount of packaging material is eliminated. Although this can be reused in a recycling process. The losses are still considerable.

It turns out therefore for a tamper-proof packaging bag the task that when removing the

Filling surface with the wicket perforation occurring

Losses to keep lower, possibly even to announce.

This object is achieved by a film tube according to the invention, which carries a wicket-perforated flag which is connected to a bag flat side in the region of the open bag end.

Accordingly, the bag design according to the invention is based on a bag in which the film tube material itself is not provided with a wicket perforation, but an additional part is glued on, welded on or fastened in another way, the additional part being in the form of a flag "denotes 1st. Bs may also be waste sections prepared in a similar manner. The "flag" may preferably be rectangular, but also polygonal in some other way, for example square or triangular.

Preferably, the flag is on a bag outside

attached. However, it is also possible to attach them to an inside, for example, to report any damage or erosion of the outside.

If the film is designed as a rectangular strip, it is arranged with one of its length sides parallel to the Abwängschnittkante.

As already indicated, it is advantageously possible for the flag carrying the bracket perforation also to be fastened detachably or detachably on the flat side of the bag. In this case, it is possible that the flags hanging on the wicket thorns as a whole are taken back by the bag manufacturer and used again as flags in the sense mentioned.

It is also possible to use the flag with a

and the perforation and perforation perforation lying Sollrlßllnie.

An execution game of the innovation is shown in the drawing.

The bag 1 produced from a film tube in a catfish known per se consists of a paper or K) plastic web, if appropriate also composite materials, of a suitable type. In principle, all web-form materials which are used in the packaging industry can be used.

The bag is closed at its head end by means of a transverse weld 2. By an inner fold 3, the Rare walls are slightly turned inside. Its lower end 4 is open. In the present case, the state is drawn shortly before filling. The bag is inflated by a stream of air.

At one of the flats 5 a rectangular, provided with a wicket perforation 6, 7 flag 10 is attached. The flag 10 is made of a plastic film material, which usually corresponds to the material of the bag 1, but of course does not need to be printed or otherwise processed. For example, it may also be cut from trimmed "waste" strips. The Wick ^ t perforations 6, 7 have the

3Q customary, to wlcket-thorns compatible distance and diameter.

The flag 10 is connected via a weld 9 with the bag outside 5. In this case, the weld is possibly placed close to the edge 11 of the open end to accommodate this part there during the later folding of the floor area.

The flag 10 can continue on a Sollrißlinle 12th

so that the machine-filled bags can be torn off the wicket in a simple catfish and avoiding all damage, with part of the

Flag on the wicket remains.

Expressly, however, is also pointed to the possibility of attaching a whole removable flag 10, which remains after filling and removing the wicket to the latter and is reusable.

The essential basic idea of ​​the invention, namely to minimize the cutting and packaging waste world-wide, can be optimally fulfilled with a bag of the type described above.
