    PalSack®01 Bag Filling Station - Containment, accuracy, cleanability

    Our PalSack® 01 bag filling system provides accurate dosing of dry material via an integrated screw feeder. The PalSack® 01 bag packaging machine can be used to fill all types of bags, such as: burlap, paper, plastic, open mouth, lined, single layer, double layer, microperforated, etc., and ranging in weight from 10 to 100 lbs. The obtainable production rates can reach up to 100 bags / hour.

    The bagging machine offers many integrated features, such as: bag stitching, removing the internal liner, automatic weld sealing for water tight closure, motorized roller conveyor, vacuum bag lifter, etc.

    Equipment Advantages:

    • A double jacketed filling head with an inflatable seal or clamping jaws for a secure connection and dust containment.
    • Loss-in-weight (LIW) or gain-in-weight (GIW) functionality
    • A dosing system adapted to your production and process requirements (precision, cleanability, flow rate, etc.)


    Possible configurations of the PalSack®01 model:

      Ref. Available equipment Functions Advantages
    Choice 1 J Inflatable seal Dust tight bag connections Maximum confinement
    M Clamping jaws Quick bag connections Speed, ergonomic installation and multi-format bags
    Choice 2  P Support tray Tension of the bag during filling Hygiene, height adjustment for adaptability to multi-format bags
    C Motorized roller conveyor  Holding and evacuation of the bag during filling  Ergonomics, increased speed
    Choice 3 Net Net weighing  Provides accurate amounts of the packaged product Accelerated rate (dosing in hidden time) / may require a double check weighing system
    Gross Gross Weighing Weighing of the entire container and contents  Commercial weighing, traceability

    Our PalSack®01 packaging machine is configurable by modulating the basic possible equipment: Choice 1 + Choice 2 + Choice 3.
    Possible reference example: PalSack®01-J-P-Net

    Choice 1: Two types of bag connection styles:

    • "J" Inflatable seal: This provides a completely dust tight connection. The double-envelope design balances the material to escaping air volumes. A hygienic design is possible for easy dismantling of all parts to be cleaned. 
    • M" clamping jaws: The docking of the bag by half-moon clamps is designed with an oval shaped fill head with two jaws actuated by a pneumatic cylinder. This connection method is recommended when filling bags that are suspended over the station.

    Our engineering office can customize solutions for your automatic bagging machines according to your plant’s production and design requirements. Our team can work with you to offer tailor-made solutions, after visiting your site and upon receiving your precise specifications.

    Palamatic Process also offers a range of semi-automatic or automatic bag filling systems for open mouth bags. The purpose of the bagging machine is to package powdered or granular products in open-mouth bags. The filling station is suitable for a large number of bags and is characterized by its ease of use.
