Horizontal Form Fill Seal – The Ultimate Guide

Horizontal form-fill-seal packaging machines offer an effective and reliable solution in the packaging industry. With its unique design, you can adapt it to fit the most dynamic application requirements.

What is HFFS?

This is a packaging process that operates horizontally. This process entails all the processes involved in manufacturing a complete pouch product i.e. film unwinding, formation of the pouch, filling, and sealing.

Benefits of utilizing Horizontal Form Fill Seal Machinery

HFFS is the most popular method of packing used in various manufacturing industries, it is preferred due to the following reasons;

· Enhances Efficiency

The HFFS machines use a high speed which enables them to package many products within a short time and a single operation.

An approximation of about 75 bags can be packed per minute using the HFFS machine, this will not only saves on the packing time but also provide a consistent and increased production rate.

· Offers a Wider Range of Packaging Solutions

HFFS machine provides all-in-all solutions for packaging, filling, and sealing products in a single operation. This helps in reducing the time needed for packing products and also minimizes the labor cost while maximizing on productivity.

Moreover, the horizontal form fill seal machine provides an extensive range for length adjustment, making it more suitable for packaging a wide array of products.

· Cost Effective

Bags packaged using the horizontal form fill seal machines are usually light compared to other packing methods, this may help in reducing the transit cost. Due to its cost-effective nature, the HFFS machine has been the best option for making promotional samples.

Sachets and pouches made using this method are usually less expensive as compared to the pre-made ones. Besides, the machine is designed to be operated by a few individuals meaning, multiple workers will not be required to run the packaging line hence saving on labor costs.

· Minimizes Material Wastage

The fact that sealing and filling are done in line with the formation of pouches, helps in reducing material wastage. With these machines, you can maximize material efficiency by horizontally creating filled and sealed units while minimizing material waste.

The design of the machine incorporates a modular framework construction.

It is majorly made up of three modules i.e. the unwinder, dosing-sealing, and pouch-forming modules which function independently to ensure the precision and efficiency of the packaging process.

The unwinder functions in providing a continuous roll of packaging material to the pouch forming and sealing sections of the machine.

The pouch forming module then transforms the continuous rolls of the packaging material into formed pouches.

Dosing-sealing modules function by filling the formed pouches with a specific weight or volume of a product and then sealing by closing the pouch to protect the product.

It is important to note that, these modules are available in various versions depending on the product to be filled and the application of the machine.

How HFFS Machine Works

HFFS machine is a packaging machine that works by first unwinding the film, pouch forming, filling, and sealing of the pouch.

The packaging material and film are usually folded by the machine and then sealed from the bottom or under.

It is sealed on the sides or shaped using the same machine and cut on the top part to form a pouch.

Filling is then done through the open top part of the pouch and there are various methods involved in filling depending on the product to be filled i.e.

  • Hot fill which is majorly for heat-processed products.
  • Ultra clean fill which is mainly for products to be used in cold chain distribution.
  • Clean fill which is majorly for non-heat processed products.

Sealing then follows to close the pouch and to protect the product filled in the pouch.

There are various methods employed by the HFFS machine in pouch sealing and they are based on various principles, for example;

  • Ultrasonic seal which works on the principle of ultra-sound frequency
  • Induction seal which works on the principle of electromagnetic resistance. This method does the sealing and cooling at the same time making it suitable for packaging in circular economy.
  • Heat seal which is based on the principle of electric resistance.

Differences between HFFS and VFFS

HFFS and VFFS are major packaging processes used in major packaging industries, however, they differ on their methods of operation.

HFFS is the most popular method and is known to operate horizontally while VFFS is a continuous process for packaging which operates vertically to create filled and sealed units with minimal waste.

The other differences between HFFS and VFFS include;

HFFS is capable of packaging a diverse range of products in contrast to VFFS.

Less floor area is required in VFFS since the process is done vertically unlike the HFFS which may occupy a larger floor area.

HFFS allows for a wider variety of packaging closures and types than VFFS.

For heavier products, HFFS is preferred over VFFS as the product travels along the conveyor belt instead of being fed from a feeding spot.

VFFS is perfect for sealed pouches and sachets rather than units with other closures i.e. nozzles or zips.

VFFS is considered more cost-effective than the HFFS and hence can fit the majority of budgets. However, it is also important to note that HFFS is also cost-effective but not as effective as the VFFS.

When it comes to uniform solid items like snack bars, biscuits, tissues, etc, HFFS emerges as the ideal packaging method and is favored over VSSF.

In HFFS, it is possible to package up to 70 bags per minute, whereas in VFFS, approximately 100 bags can be packed within the same timeframe.

Applications of HFFS

HFFS machines are majorly used to process powders, granules, and liquids in various sectors.

Manufacturers from various sectors sort to use this method in the production line when packaging their final products at big volumes.

Some of the key sectors/areas where this method can be applied include;

  • Chemical industries
  • Agricultural industries
  • Cosmetics
  • Food and beverage packaging
  • Pharmaceuticals
  • Confectionery

The HFFS machines are often selected for this operation due to their high level of efficiency and simple operation.

Conclusion

Horizontal form fill seal machine revolutionizes packaging with precision and efficiency. This method streamlines production by maximizing productivity while minimizing material wastage as well as the labor cost.
