Electrolytic Tin Plate Sheets for Making Food Cans with Excellent Corrosion Resistance
Basic composition:
With a stampable thin steel plate as the substrate, tin is plated on its surface through an electroplating process to form a steel product with a multi-layer protective film.
Principle of corrosion resistance:
In the inner wall of a food can filled with a complex mixture (or in a weak acid solution) and with a certain vacuum, the potential of tin is lower than that of the base material iron. Tin is the anode, and its dissolution protects the iron; and during the shelf life of the food can, the amount of tin dissolved is basically harmless to the human body. When the outer wall of the can is in an atmospheric solution, the tin coating is in a cathodic protection state and has sufficient chemical stability.
Advantages of production process:
It is produced by electroplating process, with high productivity, low cost, thin and uniform coating, different coating thicknesses can be produced, and single-sided or double-sided plating can be performed. Compared with the hot-dip method, the thickness of the tin coating is uniform and easy to control, and the amount of tin consumed is less.
Performance characteristics:
- Excellent corrosion resistance: It can effectively prevent the corrosion of steel plates by acidic substances in food and extend the shelf life of food cans.
- Non-toxic and tasteless: ensure that no harmful substances are released when in contact with food, ensuring food safety.
- Surface gloss: beautiful appearance, easy to print and decorate, and enhance the market appeal of the product.
- Light weight and high strength: relative to paper, wood, composite materials, etc., it has higher strength and lighter weight, which is convenient for transportation and storage.
- Easy to print, weld and process: it can be easily processed with various surface treatments and printing, and it is easy to weld and process into food cans of different shapes.
- Strong adaptability to ambient temperature: under different ambient temperature conditions, the performance is stable and can adapt to the storage and transportation requirements of food.
Application areas: more than 70% of the total output is used for food and beverage packaging, such as various meat, fish, fruit, vegetable and other food cans, as well as beverage cans, etc.
Application:
Tinplate is widely used for the packaging of products. Such as food cans,
beverage cans, pet cans, closures,general line cans and so on.
