ABSTRACT:
A method for continuous packaging in metal packages produced in situ, the invention comprises the fabrication of aluminum containers from aluminum sheet immediately prior to packaging of a material in the containers, the operations being conducted as part of a continuous flow process. The metal packages are produced by thermoforming, that is, the deformation of a heated metal body in a mold by pressure, thereby resulting in the production of containers which are aseptic and which can be easily coated with a protective layer of a plastic or similar material. The invention is particularly useful for the packaging of perishable produce.
