What is the vertical form fill seal(VFFS) machine?

The vertical form fill seal machine is a machine that packs the roll-shaped flexible packaging materials into bags, fills and seals while making bags.

The vertical form fill seal machine can pack all kinds of granular, blocks, strips, powders, liquid, sauce and other materials. Its application range is very wide, and it is used in the food industry, pharmaceutical industry, daily chemical industry, hardware industry, etc.

How Does Vertical Form Fill Sealing(VFFS) Machine Work?

A Vertical Form Fill Seal Machine, also known as a VFFS, is a common bagging machine used to package goods into bags as part of a production line.

Just as the name suggests, this machine starts by helping to form the bag from roll stock. Then, the bag is filled with product and sealed in preparation for shipment.

Step 1: Bag Forming

The initial step performed by the machine is forming the bag from the roll of film.

To do that, the VFFS 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.

Step 2: Dosing and Filling the Product

The next step in the process is filling, which is accomplished by connecting the bagging machine to multi-head scale or other filling machine, such as a multi-head weigher or other filler.

Those two machines are synced electronically, so that as soon as the bag is ready, the product is dropped in automatically.

Step 3: Sealing and Finishing

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.

What is the working principle of a vertical form fill seal machine?

First, the raw material is manipulated to be cut and then weighed. When the desired weight is reached, the system will automatically control it to stop and then continue to the next process.

After the material enters the packaging bag, the computer controls the sealing equipment of the packaging bag to seal, and then the cutting equipment cuts the packaging bag to achieve the purpose of packaging.

In addition, the packaging system is not fixed, and customers can adjust it according to their needs to achieve their goals.

What are the types of vffs machine?

VFFS machine has mechanism of intermittent or continuous. The intermittent type has a stop motion during a film feeding pitch. During the stop motion, the bottom and top seal is made by the end seal unit, which is fixed its position.

The continuous type has no stop motion and feeds film continuously. Unlike the intermittent type, the end seal unit moves up and down by following to the film feeding motion when end sealing is acted. The up and down movement prevents the product from damage that might be occurred by dropping.

Therefore, the continuous type is chosen for the case of high speed operation, for fragile and delicate products while the intermittent type is adopted for the products which do not have much worry to get damaged by fall and not required for high speed operation.

What is the difference between VFFS and HFFS?

  • VFFS systems require less floor area due to the process being carried out vertically.
  • VFFS is perfect for sealed sachets and pouches, rather than units with other closures such as zips or nozzles.
  • VFFS can fit the vast majority of budgets due to it being a highly cost-effective system.
  • HFFS allows greater variety of packaging types and closures.
  • HFFS can be used for packing a wide range of products.
  • HFFS is better for heavier products, as they travel along a conveyor belt rather than being fed from a feeding spout.

What kind of pack does a VFFS machine produce?

Vertical Form Fill Seal Machines (VFFS)  are commonly used in food packaging. Wide variety of the packaging styles that VFFS machine can produce such as normal pillow bag, block bottom bag, Pillow gusset bag, chained bags and 3-sided seal bag those are used in dependence on the product shape and nature etc. In some bag styles, wise function is added on the bag for considering easy opening for users or the convenience in the shop display.
