摘要： The present invention concerns a gusseted flexible bag In one embodiment, the flexible bag of the present invention is formed from the tube of material having a front side and a rear side. A pair of laterally disposed opposing gusset folds are formed in the tube along its sides. Each of the folds has a longitudinal crease. The bag further has a rear side flap extending from the rear side of the bag across the width of the tube which is folded over onto and hot air sealed to the front side of the tube of material. The gussets each have a slit approximate a first end of the tube thereby forming a front side flap. A front side flap may also be manufactured, if desired, which is then folded over when the rear side flap is folded so that the front side flat rests under the rear side flap. The rear side flap is hot air sealed to the front side of the bag with the front side flap being sealed therebetween. In the preferred embodiment the tube of material comprises polypropylene film on the exterior of the tube and woven polypropylene film on the interior of the tube.
