VFFS packaging machines for granular materials use measuring cups, combination scales or linear scales for measurement. The structural design conforms to the natural fall of granules to prevent material jams. It supports mixed packaging of multiple granules and is suitable for granular products such as candy, beans, and pet food. The packaging speed is 30-80 bags/minute.

VFFS packaging machines for powder materials are equipped with screw or vibration feeding devices, and have dust-proof, anti-static and enhanced sealing structures to ensure clean and complete packaging. They are suitable for fine powders with poor fluidity such as milk powder and chemical powder. The packaging speed is 25-60 bags/minute.

VFFS packaging machines for liquid materials use gear pumps, magnetic pumps or piston pumps for precise filling. They have anti-drip and hot and cold double sealing structures. They are suitable for low to medium viscosity liquids such as soy sauce and detergents. The packaging speed is 30-70 bags/minute.

The VFFS packaging machine for paste materials uses a piston pump or pneumatic filling system, with optional heating devices to maintain fluidity and nozzles to prevent contamination. It is suitable for high-viscosity products such as ketchup and honey, and the packaging speed is 20-50 bags/minute.

The VFFS packaging machine for mixed materials is equipped with a multi-channel feeding system, integrating a variety of metering devices to achieve simultaneous quantitative and packaging of materials in different forms. It is suitable for combined products such as seasoning sauce + vegetables, nuts, etc. The packaging speed is 20-60 bags/minute, depending on the complexity of the material.

The difference between vertical and horizontal packaging machines

Vertical packaging machines (VFFS) are suitable for materials with good free flow, high efficiency, small footprint, and are 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.

Advantages of Vertical Form Fill Seal Packing Machines

Vertical Form Fill Seal Packing Machines integrate vertical structure, precise filling and efficient sealing, and have multiple advantages.

The vertical design occupies a small area and uses gravity to feed materials naturally. It is suitable for a variety of materials such as granules, powders, liquids, etc., and runs stably and quickly.

The filling system can choose spiral metering, electronic scales or liquid pumps to ensure accurate metering and high packaging consistency.

The sealing system supports longitudinal and transverse sealing, adjustable temperature, adaptable to a variety of film materials, firm and beautiful sealing, and effectively prevents leakage.

What are the types of packaging bags for Vertical Form Fill Seal Packing Machines?

Vertical Form Fill Seal Packing Machines are divided into pillow bags, three-side sealed bags, four-side sealed bags, gusseted bags, stand-up bags, and connected bags.

Pillow bags (back-sealed bags) are the most common packaging form, with a middle seal on the back, a flat bag shape, fast forming, high production efficiency, and low cost. They are suitable for products such as granules, solids, and powders, and are widely used in large-scale packaging of food and industrial products.

The three-side sealed bag is sealed on three sides and one side is open for filling. It has good sealing and strong stability. It is suitable for liquid and powder products, such as seasoning sauces and medicinal powders, and can prevent leakage and contamination.

The four-side sealed bag adopts a symmetrical structure with four-side sealing, neat edges and regular bag shape. It is often used for fine foods and health products.

The corner-inserted bag (eight-side sealed bag) has four corners inserted and top and bottom seals, a total of eight sides are sealed, the bag shape is three-dimensional, and the visual effect is good. It is often used for nuts, pet food, and coffee beans packaging.

The vertical bag has a bottom support design and can stand independently. It is often equipped with zippers or nozzles. It is easy to use and suitable for sauces and liquid products, such as jams, laundry detergents, beverages, etc.

The connected bag is connected by multiple small bags with easy-tear lines or heat seals, which is convenient for subpackaging and combined sales. It is suitable for trial packs and small packaged seasonings to meet the needs of promotion and split use.

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: heat-seal the left and right sides of the packaging film longitudinally to form a cylindrical bag.

Vertical sealing affects the stability of bag forming. If the seal is not good, 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.

Price of Vertical Form Fill Seal Packing Machines

The price of Vertical Form Fill Seal Packing Machines is mainly affected by function, configuration and bag type.

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