VFFS belts with PA fabric in the suction channel

In many vertical form-fill-seal machines, our timing belts help ensure reliable packaging of products such as gummy sweets, crisps, breakfast cereals, nuts, biscuits and pet food.

How does a VFFS machine work?

A vertical form-fill-seal machine, or VFFS machine for short, forms a tubular shape from a flat film foil. The tube is filled from above and then sealed into individual bags.

Vacuum belts support the controlled downward transport of the film. Depending on the machine design, they operate with vacuum to grip the film securely and guide it evenly.

 

Less friction in the suction channel. More flexibility in belt design.

For particularly efficient film guidance, we also offer our VFFS belt models with PA fabric in the suction channel.

The integrated polyamide fabric reduces friction between the vacuum unit and the timing belt. Thanks to its low thickness, it adds only minimal build-up in the suction channel and enables improved film guidance, especially with low tooth heights, for example with a T5 pitch.

Variable conveying-side coatings, different surface finishes and a range of suction channel widths make the belts highly versatile and allow application-specific adaptation to the film and machine.

Further benefits with Esband

• No additional liquid bonding
  The PA fabric is integrated using a thermal process, eliminating the need for liquid bonding and supporting clean processing with a lower environmental impact.
• Homogeneous joint connection
  The tested fabric connection and very high homogeneity support smooth belt running and contribute to high operational reliability.
• Water-resistant fabric bond
  The water-resistant PU bond ensures a reliable connection between the fabric and the belt, even under demanding ambient conditions

 

The result is a timing belt precisely matched to the requirements of vertical form-fill-seal machines: reliable in operation and flexible in design.
