AbstractA process of packaging goods particularly foodstuffs in which the goods are placed in a first container for example a plastics bag or a tray having a deformable lid, sealing the container except for an aperture provided by an open valve. The container is then placed in a second container having rigid walls. A vacuum is then created in both containers after which the inner container is completely sealed by for example closing the valve whilst preventing the entry of undesireable substances. In a preferred process an inert or preserving gas is introduced into the first container prior to sealing.
