Tinplate steel performs well in corrosion resistance due to the protection of the tin coating. Especially in contact with food or liquids, the corrosion resistance of tinplate steel can effectively prevent the penetration of moisture and oxygen, and maintain the freshness of the contents of the can.

Tin plate sheet is based on low carbon steel, and then coated with a thin layer of tin (usually 0.08 mm), which not only has an anti-corrosion effect, but also gives the tin plate sheet good gloss and workability.

Tin plate sheet is not essentially a single metal, but a composite material composed of steel and tin. Its main component is low-carbon thin steel plate with a thin layer of tin on the surface. Main uses of tin plate sheet: 1. Food packaging 2. Beverage packaging 3. Cosmetic packaging 4. Chemical containers 5. Industrial parts and tools 6. Stationery and daily necessities

As one of the choices for food packaging, tin plate cans have many advantages, one of the important reasons is the extension of product shelf life. Tin packaging can effectively block the intrusion of light, moisture and oxygen, thereby reducing the impact on product quality.

The chemical properties of tin are relatively stable, and it has strong resistance to chemicals such as acids, alkalis, and salts, which means that it is not easy to react with other substances. Unlike iron, tin is not easy to rust, and it has high safety in food contact and does not produce substances harmful to the human body.

Depending on the different ink types, coating protection and storage conditions, the service life of the LOGO on the tin plate cans under normal conditions will vary. Generally, a properly protected tin plate cans LOGO can remain non-fading for 3 to 5 years in a cool and dry environment indoors.

During World War II, there was a shortage of tinplate sheet, which prompted people to look for alternative materials to meet packaging needs. During this period, aluminum became the main alternative material for the manufacture of seamless can-shaped packaging containers.

Tinplate is a tin-plated steel. It is made of cold-rolled low-carbon steel plates or steel strips through a precise process. Five common applications of tinplate: 1. Food packaging industry 2. Chemical product packaging 3. Daily necessities and cosmetics packaging 4. Toys and crafts 5. Electronic product housing

The production process of tinplate sheet includes raw material preparation, cold rolling, pickling, annealing, electroplating tinning and post-processing. These links cooperate with each other to ensure the quality and performance of the final product.

Process of tinplate sheet tinning: 1. Pretreatment of steel sheet ● Degreasing treatment ● Pickling ● Surface activation 2. Process of electroplating tin ● Setting of electrolytic cell ● Applying current ● Control of coating thickness 3. Post-treatment process ● Passivation treatment ● Oiling
