Vertical Bagging Services (VFFS)

What is Vertical Form Fill Sealing (VFFS)?

Vertical Form Fill Sealing (VFFS) is a packing method that forms and packs bags at the same time, vertically – hence its name.

It’s an automatic process that forms flat wound film into plastic bags, fills and seals them. As one bag is sealed, the bottom of the next one is created – so, products are created instantly. And products are weighed as part of the process, so all doses are accurate.

Vertical bagging machines offer different width sizes and directly print products with custom branding, so they’re ready to go in seconds.


WePack's VFFS services are some of the best in the industry. We offer top-quality machines that easily handle a variety of products, from loose, dry goods to powders and granules. Our machines are accurate and efficient, meaning your product will be packed perfectly every time.

And because we use state-of-the-art technology, our machines can print custom branding directly onto your product packaging. So not only will your products be packed perfectly, but they'll also look great on the shelf.

What products are suited to VFFS packing?

VFFS packs loose, dry products effortlessly. It lends itself to packing and preserving food – using a process called gas flushing to keep products fresh until they reach the consumer.

Gas flushing is a food preservation method that involves displacing the oxygen in a package with inert gas, such as nitrogen, carbon dioxide, or a combination of the two. Its purpose is to prevent oxidation and maintain product quality.

Gas flushing is often used in conjunction with a foil laminate layer which adds extra protection by preventing flavours and scents from leaking out of the packaging, keeping them fresh and potent.

This process is essential for oxygen-sensitive products, such as coffee and tea. The foil laminate also protects against moisture, making it an ideal solution for products such as powdered items and cereals.

Liquids can also be packed using VFFS, for example, creams, lotions and even condiments like mayonnaise. Less delicate items can even be flat packed to save on space and transport costs.

Other items suited to VFFS packing include:

  • Powders
  • Rubs
  • Spices
  • Sweets
  • Seeds
  • 5 or 10ml liquid samples


How Does VFFS Actually Work?

The VFFS process is quite simple. It can be broken down into the following steps:

1. Forming - the machine is first loaded with a roll of packaging film to form a tube and clipped at the bottom

2. Filling - the product is filled into the pack, falling down vertically through the forming tube and inside the open, semi-formed bag

3. Sealing - the top is sealed to close the pouch, forming the bottom of the next bag and the bottom seal is created by cutting in the middle from the next pouch

Additional Features

Any extra features are dependent on the make and model of the machine being used. Some common additional features are:

  • Weighers
  • Printing of logos, product information, barcodes

Horizontal vs Vertical Form Filling and Sealing

Horizontal form fill and seal (HFFS) and vertical form fill and seal (VFFS) are two types of form fill and seal methods. They refer to the horizontal filling and sealing of a product of which the sides are cut, and the vertical filling and sealing of a product that's cut top and bottom, respectively.

What raw materials can be used for vertical fill seals?

Any material that is granular, loose, and dry are ideal for VFFS. This can include:

  • Powders
  • Spices
  • Seeds
  • Ingredients
  • Other similar products

How is the bag sealed?

The bag is sealed via a crimp seal that is created through heat and pressure.

HFFS vs VFFS Machine

The two types of FFS machines, horizontal and vertical, distribute their content differently, meaning that they are tailored to specific types of products. It's important to remember:

  • HFFS: ideal for solid, single products like small toys, soap, candy bars etc. that are easy to handle
  • VFFS: ideal for granular and loose products that are difficult to handle/carry such as sugar, salt, spices, powders, etc.
