With excellent printing performance, noble metal texture and excellent flavor, metal packaging has an irreplaceable position in the food packaging industry, such as tea cans, moon cake boxes and milk powder cans, such as metal packaging in the domestic food packaging market has an undesirable position, is a market opportunity to pay attention to the related enterprises. Rapid growth of food products and promotion of metal packaging industry With the rapid development of the metal packaging industry, the demand for steel for metal packaging is increased, and higher requirements are put forward. The metal packaging tank products are mainly iron metal packaging cans, two beverage cans, three pieces of beverage cans, milk powder cans, ordinary food cans, air mist cans, crown cover, spinning cover, easy to pull cover, mixed cans, chemical cans, 200 liters of steel barrel and so on. Most of the materials used for metal packaging cans are steel and aluminum, including low carbon steel plate, iron sheet (commonly known as electroplated tin sheet), Wuxi steel plate (chrome plated steel plate), white iron (galvanized sheet), coated steel plate, coated iron, aluminum sheet, aluminum foil, aluminum coated film, etc. The rapid growth of food and fast consumer goods is the first traction of the rapid development of the industry, and the upgrading trend of the packaging products will directly enhance the share of the metal packaging products in the various types of packaging products; future metal packaging will pay more attention to food safety, pay more attention to reducing and reducing the thinning and reduction, and pay more attention to the recycling. About 2/3 of steel cans in Britain are made from recycled materials. In some European countries, the recycling rate of metal cans is over 90%. Therefore, the new requirements for the steel made of metal packaging cans, such as containers, ordinary steel barrel and other metal packaging containers, have greater strength and stiffness, and have the advantages of low cost and good processing performance, so the steel plate is required to have high strength and stiffness. Furthermore, the packing cans of weak acid foods require a certain corrosion resistance of the steel plates, such as meat, fish, poultry, dairy products, vegetables, carrots, peas, beets, potatoes, and all kinds of drinks and soups. At present, chrome plated steel is mainly used for making beer bottle cap, beverage and neutral food tank coating cap in China. This requires a greater corrosion resistance of the steel plate. |
