These HFFS flat pouch packaging lines work with rollstock film and handle the full process in one continuous flow, including pouch forming, dosing, cutting, opening, filling, sealing, and weight control. The mechanical structure and control system work together so the packaging machine runs smoothly without frequent stops, keeping movements well synchronized and allowing production to stay steady at around 40 pouches per minute. These rollstock flat pouch packaging system are suitable for small-volume products such as pharmaceutical powders and grains, as producers need a line that can run steadily, handle large quantities, and keep packaging costs under control.
