An airbag (20) for use in a cargo bay of a transport vehicle for buffering and stabilising a load, usually large paper rolls or drums, comprises two inflatable, gas tight bladders (22, 24) surrounded by a multi-ply paper container (26). The bladders (22, 24) are situated in a partially overlapping relationship with respect to one another. This enables a load with a rounded configuration to be cradled, buffered and stabilised while minimising the need for additional packing or supporting materials.
