How does a VFFS packaging machine work?
Oct 28,2024 | Views: 54
A Vertical Form-Fill-Seal (VFFS) packaging machine is used for packaging a variety of products, particularly in powder, granule, or liquid form. Here’s how it generally works:
1. Film Supply:
The process begins with a roll of packaging film, which is fed into the machine. The film is usually made of plastic and can be printed with branding or product information.
2. Forming the Bag:
The film is unwound and guided into a vertical tube where it is formed into a tubular shape. The edges of the film are sealed together to create a continuous tube.
3. Filling:
The machine then fills the formed bag with the product. This filling process can vary depending on the type of product being packaged. For example:
- Powders and Granules: A volumetric or gravimetric filler may be used to dispense the right amount of product into the bag.
After filling, the bottom of the bag is sealed, and the top is often left open for further processing. The sealing is done using heat or pressure, depending on the type of film used.
5. Cutting:
Once filled and sealed, the bag is cut from the tubular film. This action creates individual packages that can be collected and further processed if necessary.
6. Discharge:
The finished bags drop down and are collected in a designated area or moved to another part of the production line for additional handling or packaging.
7. Control System:
Modern VFFS machines are equipped with control systems for monitoring and adjusting parameters such as film feed speed, filling volume, and sealing temperature for optimal performance.
Overall, the VFFS packaging machine is efficient, allows for high-speed production, and is versatile enough to handle a variety of products in different weights and sizes.

- Liquids: Liquid fillers like pumps or nozzles fill the bags accurately.
After filling, the bottom of the bag is sealed, and the top is often left open for further processing. The sealing is done using heat or pressure, depending on the type of film used.
