A Primer on the Dynamics of Vertical Form Fill Seal (VFFS) Machines

What is vffs machine

vertical form fill seal machine diagram

As a rollstock packaging machine, the VFFS (Vertical Form Fill Seal) packing machine takes center stage.

Their mission? To form, fill, and seal packages, all while defying gravity by doing it vertically.

They take a roll of plastic film and, in what seems like a magic trick, transform it into a bag, fill it with the product, and seal it tight.

How VFFS Machines Work


Now, hold onto your seats as we unravel the mystery behind the workings of a VFFS machine. It’s no Hogwarts, but it’s just as fascinating.

First, the VFFS film unwinds from the roll and passes over a forming collar, which shapes it into a tube. Simultaneously, the machine heats the edges of the film and seals them together, creating a vertical seam. This forms the ‘back’ of the package.

Next comes the filling. The product—be it potato chips, ground coffee, or even hardware nuts and bolts—drops into the formed tube from a dispenser above. The machine then seals the ‘top’ of this filled tube, simultaneously forming the ‘bottom’ of the next package.

Lastly, a cutting mechanism slices between the seals to separate the packages. The result? Perfectly formed, filled, and sealed packages ready for the consumer market.

Types and Features of VFFS Machines

Intermittent VFFS Machines: Your Partner in Precision Packaging

When the product you’re packaging demands precision filling or exact positioning, look no further than intermittent vertical form fill seal (VFFS) machines.

These trusty machines form a bag snugly around your product, fill it to the brim with the desired amount, seal the bag, and then cut it free from the roll—rinse and repeat for each bag.

For high-value items requiring spot-on weighing or dosing, intermittent VFFS machines are your best bet. Bonus: They’re also pros at accommodating different bag sizes and shapes.

Continuous VFFS Machines: Your High-Speed Packaging Solution

For operations that can’t afford a pause, Continuous Vertical Form Fill Seal (VFFS) machines are the answer.

They form a tube from a flat roll of film, fill it up with product, seal the bottom, cut off a bag’s worth, seal the top, and then dispatch the bag—all in one swift, continuous process.

If you’ve got large quantities of uniform-sized items like chips or candies to package, continuous motion VFFS machines are your fast-track to getting it done.

The Film Unwind ensures that the film is dispensed evenly and without tension, setting the stage for a smooth performance.

Forming Tube: The Creative Sculptor

Next, the film meets the Forming Tube. This is where the flat film takes shape – literally.

The Forming Tube molds the film into a tube shape, ready to be filled with product. It’s the creative sculptor of our team, turning a flat sheet into a three-dimensional bag.

Product Filler: The Main Attraction

Then comes the star of our show – the Product Filler.

Whether it’s chips, coffee, or candy, this component is responsible for measuring the right amount of product and guiding it into the waiting bag.

The precision and accuracy of the product filler are vital to ensuring that each bag contains just the right amount of product.

Sealing Jaws: The Reliable Guardians

As the product lands into the bag, the Sealing Jaws step in.


These are the guardians of our VFFS machine, ensuring that each bag is sealed tight and ready to meet its fans (that’s you and me).

The vertical and horizontal sealing jaws work together to seal the bag, keeping the product safe and fresh.

Bag Discharge: The Final Bow

Finally, the Bag Discharge takes the stage.

This is the component that sends off each completed bag, ready for distribution and sale.

It’s the final bow in our VFFS performance, marking the end of one cycle and the start of the next.

And there you have it, the essential components of a VFFS machine.

Each part is a star in its own right, contributing to the efficient, reliable packaging that these machines are known for.

The Selection of VFFS Machines: Key Considerations and Specifications

When it comes to investing in a Vertical Form Fill and Seal (VFFS) machine, the decision is far from one-size-fits-all.

Let’s delve into the key considerations and specifications that will guide you to the perfect fit for your operations.

Unraveling the VFFS Selection Puzzle

Here’s a handy checklist of factors to consider when selecting your VFFS machine:

Product Type: Whether you’re dealing with powders, liquids, or granules, your product type will dictate the kind of VFFS machine you need.

Product Physical Characteristics: Is your product fragile or sturdy? This will determine whether you need a gentle handling system or a more robust one.

Bag Size: Ensure your machine can cater to your bag size range. For instance, while the XH-320 handles bags from Length: 50-200mm (2.0-7.9″) Width: 40-140mm (1.6-5.5″), the larger XH420 model can accommodate bags up to Length: 180-280mm (7.0-11.0″) Width: 100-200mm (3.9-7.9″).

Production Speed: If high-speed packaging is your goal, a continuous VFFS machine may be ideal. If precision is a higher priority, consider an intermittent VFFS machine.

Decoding VFFS Specifications

Once you’ve considered these factors, it’s time to delve into the specifications.

It might sound technical, but understanding the specs can help you make an informed decision

  • Cycle Speed: This tells you how many bags it can form, fill, and seal per minute. A higher cycle speed means more productivity, but don’t forget to consider whether the speed matches your product’s nature and your line’s overall speed.
  • Bag Styles:
