A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food and many other products. Walter Zwoyer, the inventor of the technology, patented his idea for the VFFS machine in 1936 while working with the Henry Heide Candy Company . [ 1 ]
The packaging machinery involved typically forms the pouch from preprinted roll stock. The preformed pouches are shipped to a packager where they are filled and the top is sealed. The alternative is an integral form-fill-seal machine, whether vertical or horizontal. The equipment forms the pouches, fills the pouches in-line, and seals them.
Tube filling machinery: Tubes usually have viscous products and require special filling equipment. [ 5 ] Vertical form fill sealing machines form packages such as pouches. fill them and heat seal the tops.
Blister packs are created by means of a form-fill-seal process at the pharmaceutical company or designated contract packer. A form-fill-seal process means that the blister pack is created from rolls of flat sheet or film, filled with the pharmaceutical product and closed (sealed) on the same equipment. Such equipment is called a blisterline.
These are Form-Fill-Seal style machines that form the package from rolls of packaging film (webbing). Products are loaded into the thermoformed pockets, the top web is laid and sealed under a vacuum, MAP (modified atmosphere), or skin packaging producing rapidly packaged products. Thermoforming can greatly increase packaging production speed.
Packaging operations can be designed for variable package sizes and forms or for handling only uniform packages, where the machinery or packaging line is adjustable between production runs. Certainly slow manual operations allow workers to be flexible to package variation but also some automated lines can handle significant random variation.
