A method for filling an FIBC which comprises causing particulate material to flow from a container under gravity through a filling duct into the liner of the FIBC, characterised in that 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, whereby there is formed an air passage adjacent said stream, through which passage at least part of the air displaced from the interior of the liner by the particulate material can escape from the interior of the liner without significantly disrupting the flow of the particulate material.
