What is an automatic vertical form fill seal packaging machine?

An automatic vertical form fills seal packaging machine, also known as VVFS, is a popular fast-paced bagging machine used to package different kinds of goods as a part of the production-like process. What's the use of all these technological advancements if businesses won't use them to their advantage in their line of work? Whether you're packaging dry or wet food products, Smart Weigh machinery delivers go-to technology for all customers to maximize their output while maintaining the product's integrity.

The machine starts by helping to form a bag from roll stock. As the process begins, the machine feeds the film over a cone-shaped tube called a forming tube which then shapes the film into the accurate bag size and seals the bottom and the vertical seam to ensure there's no wastage of product. The width of the bag is determined by the forming tube design, while the bagging machine determines the length. An operator can swiftly change the bag width by changing it in a fresh forming tube. Seals come in various shapes and sizes, but lap and fun seals are the most common. The two film edges overlap and is held together in a lap seal, with the back of the top side sealing to the front of the bottom side. The forming tube draws the film edges together to bind the inside surfaces together in a fin seal.

Filing is the next phase in the process which is done by connecting the nagging machine to a multi-head scale or another filing machine such as a multihead weigher. As these two machines are electronically linked, the product automatically gets dropped into the bag as soon as it's ready.

The final step involves the sealing and finishing of the product once it is inside it. The top of the bag gets sealed, and the bag is completed and cuts away. It leads to the top seal on the first evil becoming the bottom of the following bad, and the process repeats itself with all the products. During the final sealing process, it is likely that the bag gets filled with air from a blower or an inert gas supply such as nitrogen. This process is done to help reduce the crushing of fragile products such as biscuits. The added benefit is the inert has, which helps drive out oxygen and prevents the growth of any bacteria or fungus that could damage the product quality. The final product finish is the hold punching used for retailing a product that is done after the Top seal is made.

This state-of-the-art packaging system can bag both solids and liquids, making it an economical and time-saving packaging method. VFFS are ranked as one of the most advanced machinery available in the market as they are built for product packaging. Today, they are used in almost every industry due to their fast-paced economical packaging solutions that help conserve valuable plant floor space.
