Shopping bag square bottom making machine | Navona

This automatic shopping bag making machine starts from the shopping bag tube. Than, the machine to make shopping bags opens and forms the square bottom (patented system by Fidia Macchine Grafiche), inserts the reinforcing carton on the bottom, folds and glues the bottom, and finally makes the holes on the handles.

Our bags making machines are suitable for short, medium and long run works. We can make office envelopes, courier envelopes, as well as central seam envelopes and envelopes with capacity.
