For corrosive products, pay attention to whether the material of the product and packaging container will undergo chemical changes. The packaging of dangerous goods cartons in Suzhou is different from that of ordinary goods. There are special methods for the packaging of dangerous goods.

For metal packaging containers, paint should be applied to the walls of the containers to prevent corrosion of the containers by corrosive commodities. For example, the inner wall of the iron barrel for packaging synthetic fatty acid should be coated with an acid-resistant protective layer to prevent the iron barrel from being corroded by the commodity, so that the commodity will also deteriorate. Another example is hydrofluoric acid, which is an inorganic acid corrosive substance, which is highly toxic and can corrode glass. Glass bottles cannot be used as packaging containers. Formic acid is volatile and its gas is corrosive. Suzhou dangerous goods should be packed in good acid-resistant jars, glass bottles or plastic barrels, tightly sealed, and then packed in sturdy wooden boxes or metal barrels.

For the packaging of flammable commodities such as yellow phosphorus, it should be put into an iron drum with a wall thickness of not less than 1 mm. The inner wall of the poke must be coated with an acid-resistant protective layer. , the net weight of each barrel does not exceed 50 kg. Another example is the Tongshui Bow [Combustible items such as calcium carbide, which decompose in contact with water and produce flammable acetylene gas, which should be packed in a sturdy iron barrel and filled with nitrogen gas. If the barrel is not filled with nitrogen, a deflation piston should be installed. For flammable and explosive products, such as products with strong oxidizing properties, when encountering trace impurities or when heated, they will rapidly decompose and cause explosions. The effective method of explosion-proof packaging is to use plastic barrels, and then put the plastic barrels into iron barrels or wooden boxes. , it can automatically deflate.
