How Does VFFS Work? | Vertical Form Fill Seal Explained
When it comes to modern packaging solutions, efficiency and precision are crucial. One of the most popular technologies used worldwide is the Vertical Form Fill Seal (VFFS) machine. In this blog, we’ll break down how VFFS works, why it’s widely used, and how Packit By VS International has become a trusted name in delivering advanced VFFS packaging solutions.
What is VFFS (Vertical Form Fill Seal)?
VFFS stands for Vertical Form Fill Seal. It’s an automated packaging process where machines form a pouch from a roll of film, fill it with product, and seal it—all in one continuous motion. This makes it ideal for industries that require speed, consistency, and versatility.
Step-by-Step: How Does VFFS Work?
-
Film Feeding
-
The packaging process begins with a roll of flexible film.
-
The film is unwound and guided through the machine.
-
-
Bag Formation
-
The film passes over a forming collar that shapes it into a tube.
-
The machine then seals the film vertically to create the bag shape.
-
-
Product Filling
-
Once the bag is formed, the product (snacks, powders, liquids, or granules) is filled into the bag using specialized fillers like multihead weighers or auger fillers.
-
-
Sealing & Cutting
-
The top of one pouch and the bottom of the next are sealed simultaneously.
-
The machine then cuts the filled pouch, ready for packaging and distribution.
-
Why VFFS is Popular in Packaging
-
High Speed – Can produce up to hundreds of pouches per minute.
-
Flexibility – Works for powders, solids, liquids, and more.
-
Efficiency – Reduces labor costs with full automation.
-
Compact Design – Saves space in production facilities.
