A bag (1) of thermoplastic foil with lateral weld seams (12, 13) has along the opening of the bag a border folded towards the inside or the outside and welded on the front and back of the opening. Two drawing strings are placed in each border fold, and the superposed ends of the drawing strings, which lie flush with the side edges of the bag, closing them, are welded with the surrounding plastic foils and border folds in their lateral weld seam and form two movable closed loops inside the border fold. Perforations shaped as a line and/or slit are provided on both sides of the bag, in the area of the welded ends of the drawing strings, forming a tear-off tab that can be laterally separated from the bag. The tear-off tabs are subdivided by a separating slit (2) that extends parallel to the bag opening (17) into four tear-off tabs (80a, b; 90a, b), so that both loops (4a, 4b) can move independently from each other in the border folds. |
