METHOD FOR GAS-TIGHT PACKING OF OBJECTS WITH FILM CLOSE TO THE OBJECTS THAT CAN BE DEEP-DRAWN USING A VACUUM

摘要

The method involves inserting objects into a shell (6) for closing the shell. A thermoformable film (4) is connected with the shell that is utilized for formation of a packaging with circulating edge (10). The thermoformable film is gas-tightly applied or welded on the circulating edge of the packaging. The thermoformable film is sectioned on a measure smaller or equal to the circulating edge of the packaging, and vacuum is sprayed in a surrounding region of the shell. Positive pressure is applied in the surrounding region of the thermoformable film. Independent claims are also included for the following: (1) a device for gas-tight packing objects with a thermoformable film under application of vacuum (2) a packaging.
