The tin-plated layer on the surface of tinplate plate can not only resist the erosion of air and moisture, but also prevent the metal from directly contacting food. Especially in acidic foods (such as canned fruit and canned tomatoes), the protective performance of tinplate plate is particularly important.

The amount of tin used in a standard tinplate can depends on its volume and the thickness of the coating. Typically, about 1 to 2 grams of tin are required per square meter of tinplate, which means that an ordinary food can does not require much tin, but its role is irreplaceable.

Tinplate sheet is a metal sheet with a layer of tin plated on low-carbon steel. In the manufacture of aerosol can, tinplate sheet has become an important material choice due to its good corrosion resistance, physical strength and machinability.

Tinplate packaging cans have extremely strong pressure resistance and impact resistance. This structural strength can effectively prevent deformation and cracking during food transportation, stacking and handling, thereby protecting the internal food from external damage.

From the perspective of recycling, tinplate sheet has a high reuse value. Its iron-based material can be melted and reprocessed, and the tin layer can also be effectively recycled. Compared with other metal materials, tinplate sheet has higher economic and environmental benefits in the recycling process.

The time of this process may vary depending on the type of equipment in the production line, the complexity of the treatment process, and the quality of the tinplate sheet. Generally, the preparation takes 10 to 30 minutes, but if special surface treatments (such as anti-corrosion, anti-oxidation treatment, etc.) are required, the time may be longer.

The offset press used for tinplate printing is different from ordinary paper printing equipment, and the equipment itself is highly customized. Because the metal material is harder, the equipment must have a higher pressure control ability during the printing process to ensure that the ink can be evenly transferred to the tinplate surface.

Although tinplate cookie cans can be washed, improper cleaning methods will indeed damage the coating. Once the coating is damaged, it will not only affect the appearance of the can, but also have a negative impact on its functionality, causing the metal part to be exposed to the air and accelerating the corrosion process.

Although offset printing technology has many advantages, with the continuous advancement of printing technology, other emerging printing methods are also challenging the status of offset printing. In 2025, new technologies such as digital printing and screen printing have gradually entered the field of tinplate printing.
