A further film is then cut to the dimension of the peripheral edge during the application of the deep-drawable film, or after its application, and the further film is subsequently or simultaneously applied to the peripheral edge. The further film remains approximately in the plane of the peripheral edge after its application. A system for the gas-tight packing of objects with a first cutting device for a deep-drawable film has at least one cutting device for a further film. ## Claims ### Claim 1 A method for gas-tight packing objects with film material bearing tightly against the objects, by means of a vacuum, comprising the following steps: inserting the object into a bowl having at least one peripheral edge; connecting a deep-drawable film to the bowl for sealing the bowl, cutting the deep-drawable film to the dimension of the peripheral edge; applying the deep-drawable film to the peripheral edge in a gas-tight manner; cutting a further film to the dimension of the peripheral edge either during or after said step of applying, without cutting the peripheral edge; and applying the further film to the peripheral edge after said step of cutting, wherein the further film, after its application, remains approximately in a plane of the peripheral edge and wherein a region of the peripheral edge remains free of the further film after said further film is applied to the peripheral edge. ### Claim 2 (depends on 1) A method according to claim 1, wherein the further film is welded onto the peripheral edge. ### Claim 3 (depends on 1) A method according to claim 1, wherein the further film is welded onto the deep-drawable film in a region of the peripheral edge. ### Claim 4 (depends on 1) A method according to claim 1, further comprising the step of introducing a protective gas in an intervening space formed between the deep-drawable film and the further film. ### Claim 5 (depends on 4) A method according to claim 4, wherein oxygen, nitrogen or carbon dioxide is used as the protective gas. ### Claim 6 (depends on 1) A method according to claim 1, wherein a normal pressure is formed in an intervening space between the deep-drawable film and the further film, and in a surrounding region of the further film on a side facing away from the bowl. ### Claim 7 (depends on 1) A method according to claim 1, wherein a film material that is unilaterally permeable to gas is used as the deep-drawable film, and wherein the deep-drawable film is arranged so that gas can be supplied from outside to the object. ### Claim 8 A system for gas-tight packing of objects with film material bearing tightly against the objects, by means of a vacuum, the object being placed in a bowl having a peripheral edge, sealed by a deep-drawable film and a further film being placed over the bowl, the system comprising: a support for the bowl; at least one sealing tool for sealing the deep-drawable film to the bowl; at least one cutting device for cutting the deep-drawable film; at least one second sealing tool for sealing the further film to an edge of the bowl; and at least one second cutting device for cutting the further film, said second cutting device being arranged such that said second cutting device does not cut the bowl during a cutting operation, and such that the second cutting device cuts the further film to a size that leaves a region of the edge of the bowl free from the further film after the film is sealed to the edge of the bowl. ### Claim 9 (depends on 8) A system according to claim 8, wherein the second cutting device comprises cutter blades. ### Claim 10 (depends on 9) A system according to claim 9, wherein the support for the bowl or the sealing tool is vertically adjustable. ### Claim 11 (depends on 10) A system according to claim 10, wherein the support has at least one support device for the peripheral edge of the bowl. ### Claim 12 (depends on 11) A system according to claim 11, further comprising a spacer plate arranged between the bowl and the further film, which plate is placed on the support device, and wherein the peripheral edge remains free at least in sections. ### Claim 13 (depends on 12) A system according to claim 12, wherein the spacer plate has at least one opening that can be brought to overlap the bowl. ### Claim 14 (depends on 13) A system according to claim 13, wherein the sealing tool has dimensions that correspond to the opening in the spacer plate. ### Claim 15 (depends on 14) A system according to claim 14, wherein the cutting device is assigned to the sealing tool and is guided near one edge of the opening of the spacer plate. ### Claim 16 (depends on 15) A system according to claim 15, wherein the cutting tool is uncoupled from the sealing tool and is spring mounted. ### Claim 17 (depends on 8) A system according to claim 8, wherein the second cutting device is assigned spatially to the second sealing tool. ### Claim 18 (depends on 17) A system according to claim 17, wherein the second cutting device rotates around the sealing tool.
