Abstract
A method for filling an FIBC includes causing particulate material to flow from a container under gravity through a filling duct into a liner of the FIBC. The particulate material is caused to adopt a free fall generally laminar flow stream which over substantially all of its length does not contact the wall of the filling duct. Accordingly formed adjacent such stream is an air passage through which passage at least part of air displaced from the interior of the liner by the particulate material can escape without significantly disrupting the flow of particulate material.
