Method of filling up and sealing a packaging that is filled with air

摘要

A method is disclosed in which a packaging that is filled with air, is filled and made airtight without a valve. The disadvantage of this method is that the air pressure in the packaging has an effect on the sealing together of the films, so that the seams can fail in the joining stage and when the packaging is finished and the parts that held the films are removed, the air space in the packaging increases, the air pressure falls and the protective effect of the packaging is considerably reduced. In the method according to the present invention these deficiencies are eliminated since the part 1, which presses the films 9 together against the base 8 protects the joining apparatus 2 during joining. <IMAGE>
