ABSTRACT:
The invention relates to a thermoplastic film bag comprising a front wall (1) and a rear wall (2), which are joined to one another by lateral weld seams (3, 4) while forming a filling opening (6) and are each double-plied in the area of the filling opening (6), and comprising two pull-strips (7, 8). These pull-strips extend over the width of the bag, whereby one is inserted between both plies of the front wall (1) and of the rear wall (2) and they are welded to one another at both ends thereof. The inventive bag also comprises a grasping hole (11) that at least partially exposes the pull-strip, and a partially detachable adhesive tape (13) is placed on the inner surface of the pull-strip (7) in the area of the grasping hole (11).
