Paper cans
At present, the annual consumption of aluminum cans in China is between 6 billion and 7 billion, raw materials are imported in large quantities, and the price is high. Together with environmental pollution and other factors, the country has no longer approved the new aluminum can production line. The ability to find new packaging containers that replace aluminum cans has become a constant concern in the industry. The birth of paper cans overcomes the shortcomings of aluminum cans and has broad prospects for development. The construction of an aluminum can production line requires at least 17 million yuan, while the paper can production line only needs 2 million yuan; the minimum batch volume of aluminum cans is 20 million, and the economic volume of paper cans is more than 20,000. Paper cans can be used in paint, chemical, food, medicine and other packaging, but also used to produce paper boxes, paper cups, paper drums and other products.
