Abstract
A vertical form fill and seal system supports a sheet of material having material segments and a tube sized for drawing edges of the elongated sheet of material together in an overlapping configuration to form the sheet into a substantially tube shape. The VFFS also includes a sealer that seals the edges of the material to one another and a gusseting mechanism sized for forming a gusseted tuck in each of a left panel portion of the material and a right panel portion of the material. A cutting mechanism removes a first portion and a second portion of a first segment of the material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall with a substantially flat, rectangular-shaped footprint.
