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 individual 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.

In a bag of the type manufactured from plastic sheet material so as to form front and rear walls, said walls having lateral margins corresponding with the lateral margins of said bag, and a handle extending upwardly near each lateral margin of said bag as an extension of said front and rear walls, the improvement comprising each handle being provided with an upright, substantially straight slit extending along the handle to permit mounting of each bag handle on a protruding arm of a supporting rack. A plurality of bags of the type manufactured from plastic sheet material so as to form front and rear walls, said walls having lateral margins corresponding with the lateral margins of said bag, and a handle extending upwardly near each lateral margin of said bag as an extension of said front and rear walls, each bag handle being provided with an upright, substantially straight slit extending along the handle to permit mounting of each bag handle on a protruding arm of a supporting rack, said bags being arranged in superposed, stacked alignment, to form a stack of bag handles along either lateral margin of said stacked bags, each stack of bag handles being joined by means of a pin weld extending therethrough to form a bag-pack, said bag-pack, in which the bags are detachably secured, having been formed by the method comprising the steps of: arranging said plurality of bags in superposed, stacked alignment; heating said pin by inserting it in an elongated passageway in a heated metal block, the length of said passageway being approximately equal to the stacked height of said bags; and pressing said pin through said aligned bags to form a pin weld therein.
