Bulk bags are ‘loose-filled’ i.e. dropped into the bag from a conveyor which also acts a grading system at which point final quality inspection is made. The logs are therefore not stacked in the bag. We know that the volume is correct as we check the volume in a metal cage measuring 1m x 1m x 1.2m or 1.6m tall. Fill these to the top and we confirm the volume is correct.
