Vertical form fill seal (VFFS) packaging machines are used in almost every industry today, for good reason: They are fast, economical packaging solutions that conserve valuable plant floor space.
In this article, we are walking through how a vertical form fill seal machine turns a roll of packaging film into a shelf-ready finished bag.
The initial step performed by the machine is forming the bag from the roll of film.
To do that, the machine feeds the film over a cone shaped tube called a forming tube, which shapes the film into the correct bag size and seals the bottom, as well as the vertical seam where the two edges of the film come together.
The next step in the process is filling, which is accomplished by connecting the bagging machine to multi-head scale or other filling machine.
Those two machines are synced electronically, so that as soon as the bag is ready, the product is dropped in automatically.
And once the product has dropped into the bag, the top is sealed and the bag is completed and cut away.
That top seal on the first bag becomes the bottom of the next bag, and the process repeats.
