ABSTRACT:
The invention relates to a method for making a vacuum-package filled with granular material. In this method, the package filled with granular material and made from a thin-walled and flexible packaging foil is placed in a holder surrounding the bottom and sidewalls of the package and comprising flat, parallel walls, and a vacuum is applied to the contents of the package and the package is subsequently vacuum-sealed hermetically. According to the invention, the contents of the package, during at least a part of the evacuation step, are compressed by moving the flat and parallel walls of at least one pair of opposite sidewalls of the holder toward each other in mutually parallel manner against the package. The invention further relates to an apparatus for use in the invention.
