1. A transport container, comprises:
wherein the transport container comprises 8 to 14 flat film bags or 8 to 12 flat double film bags and wherein each are filled with silicon fragments;
wherein the flat film bags each have a packing density of 0.88 to 1.62 kg/dm3 and wherein the flat double film bags each have a packing density of 0.68 to 1.15 kg/dm3;
wherein the transport container containing the flat film bags has a packing density of 0.81 to 1.23 kg/dm3 and the transport container containing the flat double film bags has a packing density of 0.65 to 1.06 kg/dm3;
wherein the packing density of the flat film bag or flat double film bag is greater than or equal to the packing density of the transport container;
wherein the silicon fragments belong at least to one of the fragment size classes 0, 1, 2, 3 or 4, and wherein the transport container has a length L which corresponds to the sum of a length l and a width b of a flat bag, and has a width B which corresponds to the two-fold width 2b, wherein 2b must correspond at least to l, and wherein at least 2 and not more than 4 of the flat bags form a layer N in the transport container;
wherein for a layer of 2 flat bags 2N, the bags are arranged next to one another longitudinally or transversely;
wherein for a layer of 3 flat bags 3N, the bags are arranged next to one another, with 2 of the bags arranged longitudinally and one transversely; and
wherein for a layer of 4 flat bags 4N, each 2 bags are arranged longitudinally next to one another, with the 2 bags each overlapping arranged in longitudinal direction.
