In order to ensure the tin plating quality of tinplate cans, the tin plating time is generally between 10 and 30 seconds. Short-term electroplating can obtain a uniform coating, while long-term electroplating may cause the coating to be too thick and affect the adhesion of the tin layer.

Food packaging is one of the most common application areas of tinplate cans, especially for foods that need to be stored for a long time and maintain quality and flavor. Common food products include: ·Canned food ·Candy and snacks ·Tea and coffee ·Infant food and milk powder

Aerosol cans are high-pressure, sealed containers filled with compressed or liquefied gas. Because of the high internal pressure, once the can is damaged or encounters extreme temperatures, it is easy to cause an explosion hazard. The warning sign is intended to remind consumers that incorrect use of aerosol cans may cause serious physical and chemical hazards.

Products such as tea and coffee have high requirements for the storage environment and need to be moisture-proof, anti-oxidation and light-proof. Tin can packaging has become an ideal choice for products such as tea and coffee due to its good sealing and light-shielding properties.

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.
