Abstract
A vertical stand-up pouch, flat bottom bag, or flexible package, and method for manufacturing same, constructed with a quick change module modification to existing vertical form and fill packaging machines. The invention involves producing a vertical stand-up pouch or flat bottom bag from a single sheet of packaging film by creating one or two vertical creases along the packaging film tube prior to forming a transverse seal on the tube. Such creases are formed using fixed or stationary modifications to prior art vertical form, fill, and seal machines comprising, in part, a quick change module that easily installs on the base of a forming tube.
