Cut-Out Handle - Front Facing, Reinforced

The drawing to the left depicts a plastic bag with cutout handles that have been reinforced by a second layer of plastic welded on the inside. Such bags work well unless the welded support detaches from the bags, in which case the handle then stretches to failure. Handles and their reinformcement can be further strengthened by folding the bag's top material over the handle to increase the amount of stress the handle can support.
