This machine uses pre-made packaging bags, which have good patterns and sealing quality, thereby enhancing the product grade. The bag can be reused without filling or sealing. Don't waste bags. 7. It is easy to operate. It adopts a PLC plus POD(touch screen) electrical control system, with a friendly human-machine interface and convenient operation. The Angle and time of pneumatic components can be automatically adjusted. 8.
