Abstract
The invention relates to a method and apparatus for producing a vacuum package filled with granular material. A package made from a flexible film is filled with granular product. The filled package is compressed, so that the contents form a compact whole. Then the compressed package is evacuated by means of a vacuum element which is connected to a small suction opening in the wall of the package, while the rest of the package is not subjected to vacuum.
