The carrier bag 10 produced according to the invention consists of the front wall 11 and the rear side wall 12. Both walls 11 and 12 are shown in FIG. 1 inside in the area of the filling opening provided with reinforcement strips 13 and 14. Between the walls 11 and 12 and the adjacent Walls of the reinforcement strips 13 and 14 are the fastening ends 15. 15a of the handle loops 16 and 17 arranged. The same basic training is shown in Fig. 2, but with the proviso that the reinforcement strips 13 and 14 attached there only over part of the Extend the width of the carrier bag and, unlike the illustration in FIG. 1, attached outside »Ind. The carrier bag according to FIG. 1 is a side seam bag and shows the welding accordingly the bag walls 11 and 12 by welds 18 and 19 on the side edges. during the Carrying bag according to Fig.? designed as a side gusset bag through the weld 20 represents a bag with a bottom seam.

The Fi g. 1 and 2 thus show that the inventive The solution can be used in the case of various designs of the bag 10.
