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