Vertical Form Fill Seal Machine
(VFFS Machine )
VFFS Machines
Vertical Form Fill Seal (VFFS) machines are used to vertically turn the film into a bag. It is used in most industrial productions, including low, medium and high-speed filling applications in the food and non-food industries. It usually installed in the last stage of the production line, behind the weighing machine, which is the packaging stage. Their role is to package the productso n the production line for easy transportation, storage, and sales.
Vffs packaging machine working principle is to use a single-film coil to weld the package in three places, two horizontal fork welding and one vertical vertical welding. It should be mainly used in solid loose products, granular products, liquid beverages, etc., and it can be used everywhere in industrial packaging.

How do Vertical Form Fill Seal Machine Wrok?
The VFFS is vertical packaging machine consists of the following parts: filling area, forming area, film pulling and alignment area, sealing and cutting area, Vertical form fill seal machine diagram as shown in the picture.
The working principle of the general vertical packaging machine is as follows:Prepare to pull the film. The packaging material is generally PE, PP and other materials. It is prefabricated into a roll-shaped film according to the size and pattern you specify. The film is pulled and tensioned thanks to rollers and a weighed pivot arm. It Usually placed at the back of the machine.
The bag is formed.The packaging film is laid flat and tensioned onto the former, the film is wrapped around the forming tube and pulled along the tube, just after forming, some pull down straps are installed to move the film and let it pull into a tube shaped film bag.
Vertical Sealing.When the packaging material is well wrapped on the molding and enough length , side sealing can be performed. When calculating the width of film, an extra part of the film width have inclued so that the width of the bag when it is formed is If there is overlap, use sealing pliers or sealing strips to weld the overlapping part of the overlapping materials to form a side sealing.
Bottom sealing.before the product is injected after the side sealing is completed, the bottom sealing is done by another pair of sealing rods, which can weld the material by pressure and heat.
Product filling.The product falls through the forming tube and falls inside the bag.
Top seal & cut.Once the product is dropped, the performing bottom sealing jaws are activated again, creating the top seal and when closing the bag it is cut and dropped, usually with a conveyor belt, to the next packaging step.
Purpose Of The VFFS Machine
The VFFS machine is suitable for packaging a specific quantity or weight of products in bags, suitable for solid loose materials, powders and granular products, because it uses a drop method to put the product into the bag from the tube, so it is not It is very suitable for products that are too viscous and difficult to flow, or products that are extremely deformed or broken.
Products packed by VFFS machines are wide use, such as: nuts, biscuits, candy, chocolate, potato chips, cheese, etc.
Powdered products: salt, brown sugar, cocoa powder, coffee powder, seasoning, etc.
Frozen food: frozen meat, frozen chicken nuggets, frozen fish, frozen dumplings, etc.,
There are also most fruits and vegetables, salad, hardware and so on
The performance and type of VFFS vary with different products, and our professional team will give suitable solutions for different products.
Gas flushing is a process of injecting inert gas into packaging to replace oxygen in the air, in order to extend the shelf life and improve the integrity of products. inert gases such as carbon dioxide or nitrogen are repeatedly injected and removed from the packaging to remove oxygen from the packaging, slowing down oxidation and decay of the products.
When performing gas flushing, the product type and the desired goals must be considered. In some cases, such as in red meat and fruits and vegetables, oxygen can help maintain natural color and respiration, so it needs to be left in the packaging. However, in fish and certain vegetables, oxygen can promote the growth of aerobic organisms, leading to decay and spoilage, so it needs to be excluded from the packaging.
- Product type and characteristics: Consider the shape, size, weight, texture, and viscosity of the product, as these factors can affect the configuration or suitability of VFFS machines. Products that are too large or too viscous are not suitable for VFFS machines
- Bag shape and material: Bag shapes -pillow bag( back center seal ), -3 sided seal bag , block bottom seal,Pillow Gusset bag and cent seal stick bag .etc .choose suitable packaging materials such as polyethylene, polypropylene, aluminum foil, and paper to ensure the best sealing and protection effect. VFFS machines can handle various packaging materials
- Production capacity and speed: Consider your production needs and required production speed, and select the appropriate VFFS machine model according to your requirements
- Reliability and maintenance: Choose a reliable, low-maintenance, easy-to-repair and maintain VFFS machine to ensure the continuity and stability of the production process
- Cost and budget: Consider your budget constraints and long-term operating costs, and choose the most cost-effective VFFS machine model
- Supplier credibility: Choose a reputable, experienced supplier to ensure that they can provide reliable after-sales service and support.
VFFS (Vertical Form Fill Seal) machines seal bags through a process called heat sealing. Heat sealing is a common technique used in packaging machines to join two materials together using heat and pressure. The VFFS machine uses heat sealing to seal the edges of the bag after it has been filled with the product.
