When using electrolytic tinplate sheet, avoid contact with acidic and alkaline substances to reduce the occurrence of chemical reactions. For example, in food packaging, a layer of anti-corrosion coating can be applied to the inner layer of tinplate sheet to isolate acidic substances in food.

The surface of tin cans usually has a silvery-white luster, while aluminum cans often have a silver-gray or bright silver luster. The surface of aluminum cans is smoother and more reflective.

Pressing seal is a common sealing method, which is widely used in various packaging containers such as metal cans and plastic cans. The principle is to use mechanical pressure to tightly press the joints of the can body and the lid together to form an effective seal.

Aerosol tin cans are filled with high-pressure gas. Under high temperature or severe vibration, the can may rupture, causing the contents to spray out, posing a safety hazard.

Physical properties of tinplate sheet ● Density: about 7.85g/cm³, similar to steel. ● Hardness: usually between HR30T 50-80, depending on the composition of the steel base and the processing technology. ● Tensile strength: usually between 300-500 MPa. ● Yield strength: generally 150-350 MPa.
