    • As the air is removed from the chamber, it creates a vacuum inside the bag. In the end, the open end of the bag is sealed which prevents air from entering the product.

    Vertical Form Fill Seal Machine (VFFS)


    A VFFS is also used to provide efficient and quality packaging of snacks. These are used in many industries due to their high compatibility and applications

    Working Principle of a VFFS

    • Initially the snacks are loaded into the hopper that is present at the top of the machine.

    • Packaging materials are formed into a tube by a set of forming shoulders.
    • The tubes that are to contain snacks are filled with the product from the hopper.
    • The filled tube of snacks is sealed at the bottom to create a complete packaging
    • In the end the product is sealed and is cut to a specified length.

    Horizontal Form Fill Seal Machine (HFFS)


    A HFFS has all forming, filling, and sealing methods incorporated in horizontal orientation. Precise way packaging of snacks is carried in a HFFS.

    Working Principle of a HFFS

    • A HFFS has a roller of the flexible packaging material of film or foil which further loads it onto the machine system by a continuous movement of rollers.
    • After that, the packaging material is formed into a tube by a set of forming shoulders.
    • The tubes are filled with the snacks using a filling system.
    • The filled tube is then sealed at the top and bottom to create a package, and then the sealed package is cut to a specified length.

    Multi-Head Weigher


    This machine is used to measure and fill the product into the bag. Multiple heads are weighted and filled with snacks to ensure accurate and efficient packaging.

    Working Principle of a Multi-Head Weigher

    • A multi-head weigher holds the snack material in its hopper which is further fed to the system.
    • Snacks are then distributed across multiple weighing heads, typically using a vibratory feeder.
    • Attached each weighing head uses a set of load cells to accurately weigh the product.
    • The multi-head weigher uses advanced algorithms to determine the optimal combination of weights from the different weighing heads to reach the desired target weight.
    • Accurately weighed snacks are then dispensed into a bag or other container and sealed.
