A storage device (1) for bulk material intended for powdery materials, said device comprising a flexible container (2) for bulk material and an insulating inner liner (3), of which the surface resistivity is greater than 1.0 × 1012 Ω, without a static electricity conductive layer and without a static electricity dissipation layer, said inner lining (3) covering the inner walls of the container, said inner lining (3) comprising micro-perforations that pass therethrough, distributed over the whole surface of said inner lining (3) in such a way that the breakdown voltage of said inner liner (3) is lower than 4 kV and the breakdown voltage of the wall of the container is lower than 6 kV. |
