We specialise in Bulk Bag Filling Systems, our machines are very compact and accurate. The ergonomic design of our top models mean they are easy to operate by operators of any height. 

There is minimal manual operator input. The operator applies the empty bulk bag to the machine and ties up the neck of the full bag (robotic application of full bag is possible for some specialised high cost projects). Any control panel functions from start/stop commands to accept weight and bag discharge will also be controlled by the operator.

To avoid any repetitive strain and unnecessary wear on the machinery the IBC-PF4 and IBC-PW models have an 'ergonomic' bag filling nozzle which moves down and towards the operator - making empty bag application easy and convenient. 

Most dry solid products like powders, granules, flakes, pellets and chips can be filled on a Webster Griffin FIBC filling station.
