A bag assembly (30) includes an inner bag (1) with an outer cover (20). An open end (22) of the cover (20) is positioned around a spout (6) providing an inlet/outlet for the bag (1). After the bag (1) has been filled, and the spout (6) has been sealed, the bag assembly (30) is itself sealed by the sealing of the upper end of the cover (20). The bag assembly (30) can then be inverted and with the cover (20) removed and the bag (1) lifted, the cutting open of the spout (6) will enable the discharge of the material. |
