Continuously produced plastic bags are made with cutouts in the bags to serve as handles for the bags. A rotary wheel set is used to interface with a circumferential knife blade to cut the holes in the bags. An improved bag tensioning platen and holding apparatus is provided to improve the uniformity of holes being cut in the bags.
