The vertical form fill seal machine is one of the most widely used packaging systems in many industries, especially food. By forming the package from roll film, filling the product and sealing the bag, a vertical filling machine combines all of these operations in a single system. So why should businesses choose a vertical packaging machine? In this article, you will find the advantages and applications of vertical form fill seal machines.
What is a vertical form fill seal machine?
A vertical form fill seal machine is an automatic system that forms roll packaging film vertically into a bag, fills the product into this bag and closes the pack by sealing. Also known in international literature as VFFS (Vertical Form Fill Seal), the vertical packaging machine carries out every step, from product feeding to pack discharge, in a continuous flow.
How does a vertical form fill seal machine work?
- The roll film is passed through the forming collar and shaped into a bag.
- The product is measured by the filling unit and transferred into the bag.
- The bag is closed with vertical and horizontal seals.
- The pack is cut and transferred to the outfeed conveyor.
What advantages does a vertical form fill seal machine offer?
Since a vertical form fill seal machine produces and fills the bag on a single machine, it provides more economical packaging compared to using pre-made bags. Thanks to its compact design, it takes up little space on the production floor and can be easily adapted to different products. These features make the vertical filling machine attractive for both small and large-scale producers.
What are the advantages of a vertical form fill seal machine?
- Low packaging cost thanks to roll film
- High packaging speed
- Compact, space-saving design
