ABSTRACT:
The invention is a tear away block of thermoplastic carrying bags in which each of the carrying bags have a front wall, a back wall and two handle grip punch outs in the vicinity of an upper entrance opening. The carrying bags are provided with a sinusoidal shaped entrance opening which bounds a central sine wave region with two handle grip punch outs. A rectangular reinforcing piece of plastic foil is glued on at least one wall of the carrying bags in the vicinity of the handle grip punch outs. The carrying bags are combined in the tear away block with the aid of at least one interlocking heat seal joint in an interlocking section in each of the carrying bags and may be torn away from the tear away block by a row of perforations. The central sine wave region of the rear wall projects with an upper portion above the upper edge of the reinforcing piece, while the corresponding portion of the front wall is removed or folded over so that the upper portion of the rear wall projecting over the upper edge of its reinforcing piece forms the interlocking section. The row of perforations is positioned in the vicinity of and above the upper edge of the reinforcing piece in the upper portion of the rear wall.
