Abstract
The present invention relates to a method for packing polysilicon in the form of chunks by introducing the chunks into a first plastic bag, the first plastic bag being introduced into a second plastic bag after the introduction of the chunks, or the first plastic bag already having been inserted into the second plastic bag prior to the introduction of the chunks into the first plastic bag, as a result of which the chunks are present in a double bag which is sealed, wherein the air present in the two plastic bags in the double bag after the introduction of the chunks is removed before the sealing of the double bag such that the total volume of the double bag relative to the volume of the chunks is 2.4 to 3.0.
