Packing Cupric carbonate is sealed in a polyethylene container. The net weight is 1000kg per package.
Transportation and storage precautions Cupric carbonate should be stored in a cool, dry and well-ventilated storage room. Keep container tightly closed and vertically placed on a tray. The polyethylene container must be fastened with adhesive plaster to prevent cupric carbonate being humidified and agglomerated. Cupric carbonate must not be stored or transported together with strong acids or alkalis.
