  • Method of manufacturing a top gusset bag with integral handle
    Patent number: 4913693
    Abstract: A false gusset (12, 82) is positioned between bag panels (26, 28 and 98, 100) to form a bag having a handle (24, 80) at its upper end formed by upward continuations of the sides (26, 28 or 98, 100) of the bag (10, 78). This construction removes the false gusset (12, 82) and the seals (66, 68 or 114, 116) which connects the false gusset (12, 82) to the bag panels (26, 28 or 98, 100) from the forces created by the weight of the bag (10, 78).
