ABSTRACT:
In a method for the gas-tight packing of objects with film material bearing tightly against the objects, by means of a vacuum, wherein the object is inserted in a bowl and a deep-drawable film is connected to the bowl for sealing the bowl, and wherein a bowl with at least one peripheral edge is used for forming the packaging material, the deep-drawable film is cut to the dimension of the peripheral edge and the deep-drawable film is subsequently or simultaneously applied to the peripheral edge in a gas-tight manner. 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.
