Abstract

A packaging bag made of plastic having longitudinal welds and a carrying handle. To produce the bag, the upper wall (7, 8) and the two walls (3, 4) of the carrying handle are folded in a W-shape between the side walls (9, 10) of the bag and the longitudinal welds (13, 14) are then produced. To fill the packaging bag, it is opened out in such a way that the carrying handle is opened up onto the upper wall (7 or 8) and its edges are folded in behind the side walls provided with the longitudinal welds. <IMAGE>

Plastic bags for packaging

The invention relates to a packaging bag made of plastic with longitudinal welds and a handle. . ;

ι For packaging bags that have become known in practice so far ^; In this way, the handle is attached in a rather cumbersome and therefore expensive manner. It is generally sealed afterwards on the outside of the packaging bag, which is very labor-intensive.

The invention is based on the object of creating a packaging bag of the type mentioned, in which the handle on the one hand works well and on the other hand it can be produced efficiently is.

This object is achieved according to the invention in that the upper wall and the two walls of the handle between the side walls of the bag folded in a W-shape and the longitudinal welds are six-ply in this area.

The production and connection of the handle is done with it simultaneously with the production of the packaging loot 1s, whereby a very efficient production is guaranteed and a very firm hold of the handle is achieved.

It is also very advantageous if, according to the invention, the handle is unfolded onto the upper wall of the bag and if its edges are folded in behind the side walls provided with the longitudinal weld seams.

Unfolding the handle creates a very good stack availability achieved while folding the handle edges behind the side walls gives an additional hold.

An embodiment of the invention is shown in the drawing shown. Show:

Fig. 1 shows a flat sheet cut-out,

2 'shows a section through one with longitudinal weld seams provided, but still lying flat packaging bag 1 and

3 shows a diagram of a finished and filled packaging bag.

With 1 is in Fig. ' 1 denotes a foil blank which has handle part walls 3. ** connected to one another via a fold line 2. Handle openings 5> 6 are punched into both walls of the carrying handle, which cover one another when the carrying handle is folded. In connection with the two handle part walls, an upper wall 7> 8 is arranged in each case. Adjoining these upper walls 7 and 8, side walls 9 and 10 and bottom walls 11 and 12 are arranged.

To produce a packaging bag, as shown in FIG. 3, the handle part walls 3 and the upper walls 7, 8 are folded in a W-shape between the side walls 9 and 10. Then two longitudinal weld seams denoted by 13 and 1 k are produced, which have six layers in the area of the W fold and two layers in the remaining area.

When erecting and filling the packaging bag, the
Handle 3, ** unfolded onto one of the two upper walls 7 »8. The outer ends of the handle are simultaneously folded in behind the side walls, as indicated by dashed lines in FIG. 3.

After filling, the packaging bag is placed along the
Strips 15> 16 closed.
