The Vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used to in the packaging industry for food, and a wide variety of other products (mainly powdered, granular or small solids ).
The machine constructs plastic bags out of a flat roll of plastic film, while simultaneously filling the bags with product and sealing the filled bags.

The packets are gripped and drawn down by two belts with special grip coatings which works in pairs, usually located vertically for easier filling control, measuring our of the product and correct drag of film to be welded.

When the gross weight of the product-filled bag is reached, filling stops, and the horizontal sealing bar seals the top of the bag, and simulatenously forms the bottom of the next bag above. This bag is then cut off from the tube and is now a sealed package, ready to advance onward into the product boxing and shipping processes.

The sleeve belts that draw down the sealable film play a key role in the packaging machine: the right choise of type of elastomer with which the belts are covered is an essential and critical issue in order to ensure the proper drag and then correct packaging of product.

LILIUM ® rubber is a NR (Natural Rubber) elastomer based on 100% natural caouthchouc, exhibiting excellent physical-mechanical properties:

• High friction coefficient and abrasion resistance
• Remarkable cut and tear resistancei
• High flexibility

LILIUM is a natural rubber that has been specially developed by Toscana Nastri as coating for conveyor belts, power transmission and carrier belts.

ADVANTAGES:

• Premium and homogenous friction coefficient and uniform wear among the whole lifetime of the belt
• High wear resistance
• Suitable for handling of sharp-edged material, thanks to its tenacity
• Do not damage or mark the material handled

APPLICATION:
Packaging, draw-down machines (suitable also in case of high speed)wood and paper application.
