Around the world and across industries, Automatic pouch filling machines are becoming increasingly popular for industrial packaging. Pouches are flexible, lightweight bags that offer many advantages over traditional packaging such as metal cans or glass bottles.
Pouch filling machines are typically of two types: Vertical Form Fill Seal (VFFS) and Horizontal Form Fill Seal (HFFS), with FFS being the more preferred technology.
Let's see how FFS packaging machines work.
The vertical seal filling machine is a kind of vertical structure bag making and filling machine. Mainly used for industrial packaging and processing, it provides a more convenient and efficient automatic packaging method, saving time, material waste and cost.
Understanding the main components of a VFFS pouch filling machine will explain how these machines work:
Film take-up system: This system consists of an unwinding roller and a tensioner. The film roll (usually laminated PE, PET, aluminum foil) is placed on the unwinding roller, usually located at the back of the machine. Using servomotors and a tensioner, the film is tightly and precisely unrolled and pulled into the system.
Printer (optional): The film goes through a printer where the date, batch code, etc. will be printed on the film.
Pouch Former: After printing, the film is moved to form the pouch. The process overlaps the edges of the film and shapes the bag. Vertical and bottom sealing is done with sealing jaws.
Filling and Sealing Machine: Filling is done by connecting the bagging machine to a multi-head weigher or other filling machine such as a screw or volumetric filler. The two machines are electronically synchronized so that once the bag is ready, the product is automatically inserted.
Once the product falls into the bag, the top is sealed. Sealing jaws compress 2 pieces of overlapping material and weld them together, often by heating, to form a side or center seal.
Cutting off the bag: The filled and sealed bag is cut off. This top seal on the first bag becomes the bottom of the next bag and the process repeats. The cut bag falls into a collection system, typically a belt conveyor, which feeds the bag into the next packaging step.
Control box: There is a control box on the side of the vertical mold filling machine. It contains all the electrical parts inside. PLC, contactor, servo motors, pneumatic cylinder, solenoid valves, PLC expansion mode, low pressure electrical parts. The HMI facilitates the operation and control of the machine.
There are many bag filling machine manufacturers that offer multiple machines for different applications.
