Meaning
Packaging automation systems integrate the processes of creating a container from a roll of film, filling it with product and sealing it in a single continuous operation. A manufacturer relies on form fill seal machinery to minimize human handling and increase output speeds compared to manual bag loading. The process applies to both flexible pouches and rigid tubs.
Packaging Sequence
The machine draws film over a forming collar to create a tube or into a cavity to create a tray. Inside form fill seal machinery, the longitudinal seal is formed before the product is dropped into the container. This sequence ensures that the product does not contaminate the seal area and prevents leaks.
Heat Management
Temperature control at the sealing bars determines the integrity of the final package. If the form fill seal machinery runs too hot, the film burns or shrinks excessively. If it runs too cold, the bond fails and the package leaks during shipping.
Tension Control
Constant pressure on the film roll prevents wrinkles during the forming stage. Smooth operation of form fill seal machinery depends on complex electronic brake systems that monitor the torque and adjust as the roll diameter decreases to ensure the material never sags.
