A false gusset (12, 82) is positioned between bag panels (26, 28 or 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,

A false gusset (12, 82) is positioned between bag panels (26, 28 or 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 connect 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).

A handle bag, comprising: first and second panels of flexible thermoplastic material overlying one another and together presenting an upper boundary and a lower boundary; a web of thermoplastic material folded on itself, to form two web sections joined by a bight, and two edges near each other opposite the bight, said folded web being positioned between the two panels, with the bight of the folded web directed towards the lower boundary of the panels and the edges of the folded web spaced from the upper boundary of the panels a distance at least as large as the folded width of the web; a heat seal on each side of the bag connecting an edge portion of each web section to an adjoining portion of the adjacent panel, to connect the web edge portions to the panels along lines which extend parallel to the bight and edges of the web and also parallel to the upper and lower boundaries of the panels; heat seals sealing the panels and folded web together along spaced apart lines which extend parallel to each other and perpendicular to the bight and edges of the folded web and also perpendicular to the upper and lower boundaries of the panels, to form bag side seals which connect together the two sections of the folded web and the adjoining portions of the two panels, in the region where the folded web is between the two panels, and which also connect the two panels together in the regions of the panels which extend between the bight of the folded web and the lower boundary of the panels; said panels being connected to each other and to the folded web by the heat seals in a manner so that the bag when filled can approximate the shape of a hexahedron with the web unfolded to form a closed top for the bag; said panels being connected together at the upper boundary of the panels; and wherein the portions of the panels that are located between the upper boundary of the panels and the heat seals which connect the web to the panels form a handle which extends over the closed top of the bag from one side of the bag to the other.
