Abstract

In a method for the manufacture of a packaging bag, in which a length of material with moulded material sheet 3 is drawn off from rolls in order to be turned up around a bottom fold 10 running parallel to the direction of transport, in order to form the bag part 5, and thereupon to be welded and brought together transversely to the direction of transport at the side edges 11, 12 of the bag, following which the bag contents are inserted and the bag is heat-sealed along a sealing seam 4, which joins the side edges 11, 12, and which is made by lightly pressing together the two lengths of material to be welded, welding of the tear-open sealing seam is done by high-frequency welding, and the high frequency welding jaws are in addition preheated to 40 degrees C. As a result the sealed bag can be torn open more easily than is the case with normally welded bags, so that when tearing open the welded seam 4, the two sealing seams 14 at the sides of the packing bag are not also torn open. A frequency of 27 MHz is preferably used for high frequency welding. <IMAGE>
