Packaging and Transportation: Double-layer packaging is used, with inner packaging in polyethylene plastic film bags and outer packaging in plastic woven bags or composite plastic woven bags. Each bag has a net weight of 25 or 50kg. During transportation, it should be avoided to be rained on, dampened, or exposed to the sun.
