What is Vertical form fill sealing machine(VFFS） packaging?
A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food and many other products.
The machine constructs plastic bags and stand-up pouches out of a flat roll of film, fills them with product, and seals them. Both solids and liquids can be bagged.
How does the VFFS machine work?
1，VFFS processes start with a single sheet of packaging film rolled around a cylindrical core.
2，The VFFS packaging machine then transfers the film from the roll to the forming collar, which folds the film into the appropriate shape.
3，The mating parts of the film pass through vertical seal bars, which extend and create the vertical fin seal at the back of the pouch.
4，Upon obtaining the required packaging length, operators or automatic/semiautomatic processes fill it with product.
5，After successful product insertion, horizontal seal bars close, seal, and cut the films into individual packaging units.
What is the difference between HFFs and VFFS?
Businesses often use two packaging systems called vertical form fill seal (VFFS) and horizontal form fill seal (HFFS). These systems are used to form, fill, and seal packaging. HFFS and VFFS differ in how they work and what products they can package.
The main difference between HFFS and VFFS is their orientation. HFFS operates horizontally, with products moving along a conveyor belt and being wrapped in plastic film that is sealed at both ends. On the other hand, VFFS operates vertically, with the sealing of one unit causing the formation of the next. This vertical orientation allows for optimization of time and materials since the machinery creates filled and sealed units in a continuous manner, minimizing waste.
Choosing between HFFS and VFFS depends on the products being packaged. VFFS systems are ideal for sealed sachets and pouches, especially those without zips or nozzles. It is a cost-effective solution that can fit into a variety of budgets. In contrast, HFFS offers greater versatility in terms of packaging types and closures. It can be used for a wide range of products and is particularly suitable for heavier items, as they can be easily transported on the conveyor belt.
Another difference is the space required for the two systems. VFFS systems require less floor area since the entire process is carried out vertically. This can be advantageous for businesses with limited space availability. On the other hand, HFFS systems may require more room due to the horizontal movement of products along the conveyor belt.
