Storage

The semi conductive shielding material is installed in the double-layer polyethylene film. After sealed package, it is loaded into the hard corrugated box which is not easy damaged, and the outer membrane is water proof, the net weight of each case is 600kg. It is stored in a clean, dry and ventilated warehouse, with a height of less than two layer. The transport process keeps away from sun, rain and mechanical impact.
