What are Vertical Form Fill Seal Packing Machines?

Vertical Form Fill Seal Packing Machines are devices that form packaging films, fill materials, and seal them by vertical paper feeding. The working process is as follows: the film is formed and sealed by guide rollers, and the materials are filled into bags and then sealed and cut horizontally to complete automatic packaging into bags. The packaging speed is about 30-80 bags/minute, the packaging range is about 5g-2kg, and the sealing methods are heat sealing and cold sealing. The output is affected by product characteristics and bag type, and is generally 1800-4000 bags/hour. The price varies depending on the function and model, ranging from $4,000 for the entry-level to $25,000 for the multi-functional high-end model.

Advantages of Vertical Form Fill Seal Packing Machines

The VFFS packaging machine integrates vertical structure, precise filling, and efficient sealing, and has multiple advantages.

The vertical design occupies a small area and uses gravity to discharge materials naturally. It is suitable for a variety of materials such as granules, powders, and liquids, and operates stably and efficiently.

The filling system can use spiral metering, electronic scales or liquid pumps to ensure accurate metering and high packaging consistency, which is suitable for industries with strict dosage requirements such as food and medicine.

The sealing system supports vertical and horizontal sealing, adjustable temperature, and adapts to a variety of film materials. The seal is firm and beautiful, effectively preventing leakage.

The VFFS packaging machine highly integrates the three functions of forming, filling and sealing to achieve a high-speed, fully automated packaging process. The equipment is easy to operate, supports PLC control and multi-device linkage, and can be seamlessly connected with feeding, weighing, printing and other systems, significantly improving production efficiency, reducing labor costs, and meeting the needs of modern enterprises for automation and efficient production.

Price of Vertical Form Fill Seal Packing Machines

The price of VFFS equipment is mainly affected by function, configuration and bag type.

Basic models such as VFFS-320 are suitable for powder and granule packaging, with a maximum bag width of 160mm, an output of about 30-50 bags/minute, and a price of about $4,000-$6,000, which is suitable for small and medium-sized batch production.

Mid-range models such as VFFS-420/520 have a wider range of adaptability, supporting a variety of materials such as granules, powders, and liquids. They are equipped with touch screens, servo motors, etc. The bag width can reach 250mm, and the output is increased to 40-60 bags/minute. The price is $8,000-$12,000, which is suitable for medium-capacity needs in daily chemical, food and other industries.

High-end models such as VFFS-620/720 support multi-row packaging, automatic weighing, batch number printing and other functions. The bag width can reach up to 350mm, and the output can reach 60-80 bags/minute. It is suitable for large-scale industrial production, and the price range is $15,000-$25,000. If equipped with automatic systems such as spiral metering devices, electronic scales, and bucket elevators, the total investment may exceed $30,000, which is suitable for the construction of high-efficiency automated packaging lines.

Parameters of Vertical Form Fill Seal Packing Machines

Common parameters of Vertical Form Fill Seal Packing Machines include:

Differences between vertical and horizontal packaging machines

Vertical packaging machines (VFFS) are suitable for materials with good free flow, high efficiency, small footprint, and suitable for bulk particles, powders, liquids, etc. Horizontal packaging machines (HFFS) are more suitable for regular objects such as biscuits, soaps, paper towels, etc., with various packaging forms and beautiful sealing. The center of gravity of the vertical machine is concentrated downward, which is suitable for gravity filling; the horizontal machine pushes the material horizontally and pays more attention to the appearance of the packaging. The selection should be flexibly configured according to the product status and production site.

The difference between forming, filling and sealing machines

The three are different links in the packaging process:

Forming machine: folds the packaging film or material into a bag shape, often combined with the sealing function

Filling machine: accurately delivers the material to the formed packaging bag, and the accuracy of the metering system affects the packaging consistency

Sealing machine: seals the bag after forming and filling to ensure sealing and product preservation

VFFS equipment integrates the three into one, realizing synchronous linkage, which is an important development direction of modern packaging equipment.

The difference between horizontal sealing and vertical sealing

Horizontal sealing: that is, the horizontal sealing completed by the upper and lower heat seals, which determines the sealing effect of the upper and lower edges of each bag.

Vertical sealing: the left and right sides of the packaging film are longitudinally heat-sealed to form a cylindrical bag body.

Vertical sealing affects the stability of bag forming. If the sealing is poor, it will cause air leakage or powder leakage; horizontal sealing is related to the overall appearance and sealing quality. Only when the two are properly coordinated can high-quality packaging be achieved.
