Servo – Vertical Form, Fill & Seal

Vertical Form, Fill & Seal

Vertical form fill and seal applications utilise servo motor technology to accurately pull and feed plastic fi lm material from a roll stock to be heat formed, volume dosed with a product, and then sealed and cut to be carried away by an unloading conveyor. While the methods for fi lling and sealing vary from machine to machine, vertical form fi ll & seal applications are essentially organized into two categories; Continuous motion bagging machines and intermittent motion bagging machines.

Product entering the feeder can vary from a viscous fl uid to a solid material and will often play a key role in how the machine is designed.


Example Applications

Applications suitable for vertical form, fi ll & seal operations include but are not limited to:

♦ Food/beverage bag filling

♦ Pouch packaging

♦ Industrial powder filling
