Abstract
A method is disclosed for packaging polycrystalline silicon, in which a plastic bag is filled with polycrystalline silicon by means of a filling device, which has a freely suspended energy absorber consisting of a nonmetallic low-contamination material, wherein the plastic bag is pulled over the energy absorber and filled with polycrystalline silicon, and the plastic bag is lowered downward during the filling, so that the silicon slides into the plastic bag. Also disclosed is a method for packaging polycrystalline silicon, in which a plastic bag is filled with polycrystalline silicon by means of a filling device, wherein a storage container has an opening through which it is filled with silicon, the plastic bag being pulled over the storage container after filling the storage container with silicon and the storage container subsequently being rotated so that the silicon slides out of the storage container into the plastic bag.
