Packing:It is packed with polyethylene bag as liner and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg.
Storage and Transport:It should be stored in a dry and ventilation warehouse, kept away from moisture and hot. Furthermore, it should be stored separately from poisonous substances; unload with care so as to avoid damage to packing.
