Abstract
A vertical stand-up pouch, flat bottom bag, or flexible package, and method for manufacturing same, constructed by 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 forming one or two vertical creases along opposing sides of the packaging film tube prior to forming a transverse seal on the tube. The vertical crease is formed using a pivoting tucker mechanism positioned outside the packaging film tube and between two forming plates positioned inside the packaging film tube. A novel method is also disclosed for adjusting the orientation of labeling on the packaging film, which results in the production of innovative packages.
