M520 Vertical Bagger

The Model M520 is an intermittent vertical bagger for snacks, cereal, coffee, tea, rice, nuts, candy, granular, liquid and powder products in pillow or gusseted bag. It can make a bag up to W245 x L390mm.

The reel film is mounted at the back of the machine with our innovative simply structure design, the tension roller assembly ensure the film's tension when entering the forming shoulder and the stability of the reel unwind mechanism. The shoulder forms the film into a tube shape, where it is sealed at the back and bottom by the vertical seal and transverse seal respectively. The product is then drop into the bag through the forming tube. Next, the bag is drawn downward by dual friction drawn belts, sealed at the top, and cut off to complete the packaging process.

The M-series is engineered to ease machine control and shorter maintenance / changeover time. Machine function time can be calibrated independently to match the flow rate of different products, to increase efficiency.
