Abstract
The invention relates to a method for producing an especially panel-shaped vacuum insulation element which is wrapped in a film and is filled with a powder. According to the method, the unmolded, loose powder is filled, particularly poured, into the opening of a bag which is formed from a high-barrier film and is open on one side. A filter material that is permeable to air and impermeable to powder dust is fixed to the internal face of the film bag in the area of the opening of the filled film bag such that the interior of the bag is closed in a dust-tight manner while air can still be discharged. The interior of the dust-tightly closed film bag is then evacuated and the evacuated film bag is air-tightly closed in a vacuum.
