GB50 Gross Bagging Machine

Gross Bagging Machine Description

QWM now supplies the BudPak GB Series of gross baggers. BudPak is ofcourse a packaging icon in Australia and the GB Series is a fully matured Series that has been around for many years with a proven track record.

Gross bagging machines are easily defined as bagging machines that use the weigh bin and discharge chute as one and the same. As each empty bag is placed over the discharge chute and secured in place, it must be tared off before product can be discharged in to the bag.

This is a distinct difference to net weighers that have a separate weigh bin and discharge chute and product weighing can begin while a bag is being placed over the discharge chute. It mightn't seem a big difference between the two, but the fact that a gross bagging machine cannot begin to feed product until that bag is in place, secured and tared off makes the difference in the number of bags that can be filled per minute between the two.


BudPak’s proven range of Gross Baggers are suitable for bagging most types of products including dry, granular, lumpy, crushed or powdered products into bags up to 50kg. Gravity, Screw, Vibratory or Conveyor Fed, the GB50 is based on digital weighing technology and pneumatic control. Over many installations, the design has proven to be both reliable and accurate.

The GB50 utilises the well proven “weigh in bag” method that has been perfected over many decades. The bag spout is fully suspended on precision loadcells and the dedicated weight controller ensures that accuracy is achieved using automatic free fall compensation and two stage fill.
