HFFS Machines
For full wrap
Kallfass's robust HFFS machines create a film overlap on the underside of the products, eliminating the need for two side seals. The packaging result is perfect and achieves the desired premium look at the point of sale. The film can be sealed either by ionization or welding, producing no film waste and therefore requiring no film waste rewinding.
Versions
HFFS Machines
up to 160 cycles/min
Continuous-motion form-shoulder machines are available in the following versions
Universa 500 Servo FS
Universa 500 Servo FS-C
With a packaging output of up to 160 cycles per minute, depending on the product format.
ADVANTAGES
- High packaging output through continuous packaging without stop-and-go
- Random infeed of products of varying lengths is possible
- Packages in geometrically precise film pouches
- Easy to operate and largely maintenance-free
Form-shoulder machines are fully automatic packaging machines in which the film is drawn over a so-called form shoulder and the product is wrapped in film on all sides. The characteristic feature of this packaging principle is the overlap seal on the underside of the product — this eliminates the side seals of conventional side sealing machines.
The result is a clean, virtually seamless pack that is particularly effective at the point of sale. Since no film waste is generated, no complex residual film rewinding is required either — an advantage that simplifies operation and can noticeably reduce material costs.
Packaging examples
Continuous-motion film packaging: Servo FS series
For applications with particularly high throughput, the continuous-motion servo models operate without stop-and-go. The Universa 500 Servo FS reaches up to 120 cycles per minute. The Universa 800 Servo FS version continuously packages products at up to 80 cycles.
Both machines combine the advantages of form-shoulder technology — no film waste, high-quality film overlap on the underside of the product. The film packs are produced reliably and with consistent quality.

Packaging that sells
The overlap seal on the underside of the product results in a visually clean, professional film pack with no visible side seams on the sides of the product. Especially for products presented openly on the shelf, this is visually appealing, and no seal obscures the view of the packaging design.
All packaging machines in this series are low-maintenance, easy to operate, and designed for the availability requirements of multi-shift operation. Kallfass's quality management ensures machine availability of over 98.5%.
FAQs on HFFS machines
What is a form shoulder and how does the packaging principle work?
A form shoulder is a shaped metal element over which a flat film or center-folded film is guided in such a way that it wraps the product in a tube-like manner. The overlap seal is applied on the underside of the product — without side seals and without film waste.
What is the difference between ionization and welding as a sealing method?
In ionization, the overlapping film is bonded together by electrostatic charging — without heat and without a seal seam. Welding creates a thermal bond. Which method is used depends on the customer's requirements.
How does a form-shoulder machine differ from a side sealing machine?
With a side sealing machine, the packaged product ends up with three seals located on the sides of the product. The form-shoulder machine packages products with two seals on the ends of the product and an overlap on the underside of the product.
Which industries and products are these packaging machines suitable for?
Wherever the visual appearance of the packaging matters: food, cosmetics, medical products, books, calendars, and other goods presented openly in retail. The overlap looks more premium and is also easier to open.
Does film waste occur with form-shoulder machines?
No. Since the film is closed by overlapping, no residual film is produced that would need to be rewound. This simplifies machine operation and optimizes film consumption during ongoing operation.
