Working Principle of Premade Bag Packing Machines

The operation of a premade bag packing machine can be divided into five main steps:

1. Bag Feeding: The machine takes a premade bag from the bag feeder and positions it for the next step.
2. Bag Opening: The bag opening system opens the premade bag, usually with the help of vacuum suction cups or mechanical grippers, preparing it for filling.
3. Filling: The filling system dispenses the product into the open bag. The type of filling system used depends on the product’s characteristics, such as whether it is a liquid, powder, or solid.
4. Sealing: After the bag is filled with the product, the sealing system closes and seals the bag to ensure the contents remain secure and fresh. There are various sealing methods, such as heat sealing and ultrasonic sealing, depending on the bag material and application requirements.
5. Discharging: Once the bag is sealed, the discharge conveyor transports the finished package away from the machine for further processing or packaging.
