A quick change module operable for being removably attached to and extending below a forming tube of a conventional vertical form, fill, and seal machine to produce a wide assortment of differently sized vertical stand-up pouches or gusseted flat bottom bags. The quick change module comprises at least one pair of adjustable forming plates located below the forming tube. The lateral distance between each pair of forming plates can be adjusted by shifting the position of each forming plate along a corresponding slotted bracket. A gusseting mechanism mounted to the frame of the machine can be positioned between each pair of forming plates imparting a vertical crease along the length of the bag while it is being formed and advanced down the forming tube of the machine. By adjusting the lateral separation of the forming plates, the size of the vertical crease can be adjusted such that the resulting gusseted base is increased or decreased in proportion to size of the resulting package, thereby enhancing the overall stability of the package when placed on display.
