Abstract: A plurality of discrete packages (100) are manufactured from an indefinite length of gusseted packaging material (1). Each package (100) has an insert (9) inserted through an incision (8) in the packaging (1) which in use maintains a desired footprint of the package. Gaps (17) in welds (15) joining the bottom of the insert (9) to the packaging material (1) allow air to vent from between the insert (9) and the packaging material (1). Flaps (23) toward the rear of each package (100) join a leading package (100) to a following package (100a) by means of longitudinal welds (21) which allow gaps (22) for air to vent during the roll-up process.

Abstract: 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.
