A process of packaging goods characterized in that the goods are placed in a container (1) made of flexible thermoplastics sheet material and having a flange (2) provided with an aperture (3), partly closing the container by sealing a deformable sheet material (4) of thermoplastics material to the flange so as to leave unsealed together a part of the flange and the sheet between the aperture and the interior of the container, inserting a conduit member (7) into the aperture so as to separate the unsealed part of the flange and the sheet material, modifying the atmosphere in the container by withdrawing a part of the air in the container and introducing a preserving gas into the container, removing the conduit and sealing together the unsealed part of the sheet material and the flange whereby communication between the aperture (3) and the interior of the container is prevented.

A process of packaging goods, which comprises placing the goods in a container (1) made of flexible thermoplastic sheet material and having a flange (2) provided with an aperture (3), partly closing the container by sealing a deformable sheet material (4) of thermoplastic material to the flange so as to leave unsealed together a part of the flange and the sheet material between the aperture and the interior of the container, inserting a conduit member (7) into the aperture so as to separate the unsealed part of the flange and the sheet material thereby and so as to form an air-tight sealing engagement connection between the conduit member and the flange at the aperture for flow communicating the conduit member with the interior of the container through the unsealed part of the flange and the sheet material, modifying the atmosphere in the container by withdrawing a part of the air in the container and introducing a preserving gas into the container via the conduit member so as to exchange the air in the container by the preserving gas, removing the conduit member, and sealing together the unsealed part of the sheet material and the flange whereby communication between the aperture (3) and the interior of the container is prevented.
