BAG CONSTRUCTION AND BAG PACK UTILIZING THE SAME ABSTRACT OF THE DISCLOSURE A plurality of bags, each having an upright handle at either lateral edge thereof, is formed into a bag-pack, and the bag-pack is retained on a supporting rack by providing upright slits in the handles of each bag through which arms of the supporting rack extend. Unlike holes which are formed in the bag handles, upright slits do not cause weakening of the handles. In addition, the stacked handles of the bags are punched with a heated pin having a diameter no larger than approximately three thirty-seconds of an inch, to weld together the stacked handles of the bags, thereby permitting convenient mounting of the stacked handles on the arms of the supporting rack, without substantially weakening the bag handles. The in- dividual bags are readily detachable from the bag-pack, because the pin is uniformly heated by being placed in a passageway in a block of metal heated to a temperature in the range of about 250-260°F. The block passageway is long enough to receive at least a forward portion of the pin corresponding in length to approximately the stacked height of the bag-pack.
