1. A bag loading nozzle to confine a flow of material from an upstream feed for a downstream discharge into a bag having a spouted entrance, the nozzle comprising an interior wall presenting an inlet and an outlet, through which the material is to pass from the feed into the bag, a shape retaining tube made from rigid material located intermediate of the inlet and outlet and about the interior wall, and at least one actuable fluid inflatable collar at least substantially about the shape retaining tube, which when actuated to its inflated form will effect at least a substantial sealing with a fitted suitable bag from within its spouted entrance, and which when deactuated or otherwise deflated, allows the release of the bag from the collar, wherein a sleeve region extends downstream of an outlet of the shape retaining tube as a continuation of the interior wall, the interior wall and the sleeve region being made from a flexible material the extended part of the sleeve region including a rigid shape retaining ring located about the outlet of the interior wall and the sleeve region, and wherein the nozzle is removably engageable with a bag filling apparatus at the inlet.
