ABSTRACT:
A process of packaging goods, especially foodstuffs, comprising enclosing the goods in a sheet of thermoplastics material, preferably a bag, so as to form a package which presents two unsealed juxtaposed surfaces. The package is then placed in a container, one wall of which is made of deformable sheet material, preferably a sheet made of a silicone resin, which is stable at the sealing temperature of the thermoplastics material. The container is then connected to a source of vacuum and when the pressure has been reduced in both the container and the bag sufficient heat is applied to the deformable sheet in the vicinity of the juxtaposed surfaces to cause them to become sealed together. In a further embodiment of the invention vacuumization of the container including the bag is followed by the injection of a preserving gas such as carbon dioxide.
