Automatic multi-line packaging machine for packaging liquid products in plastic film bags. This packaging machine forms each bag from plastic or aluminum coil film. Remove the foil from the roll, divide it into two parts, and then seal one over the other creating the vertical walls of the bags just before separating them into several columns or strips. After this, introduce product into the bag to then seal them horizontally. Finally, the bags are cut into the bags giving the final shape. The trimmings are removed by a belt towards the rear of the machine and the finished bags are ejected by an exit belt towards the front of the packaging machine.
