From the perspective of material composition, tinplate products can be completely recycled. The recycling of the steel matrix is ​​no different from ordinary steel, and can be reprocessed into new steel products through smelting.

Tinplate printing coating pigments may contain heavy metal elements such as lead, chromium, and cadmium. These heavy metals are toxic and long-term contact or ingestion may have adverse effects on human health.

For conventional food cans and beverage packaging, the shelf life of tinplate products is usually around 3-5 years, depending on the nature of the contents. For some special-purpose tinplate products, such as chemical barrels or tool boxes, the service life can reach more than 10 years.

1. Demand analysis The first step in the customization process is demand analysis. Enterprises need to clarify their specific needs for tinplate products, including shape, size, printing pattern, function and other requirements. 2. Design and development 3. Material selection and preparation 4. Mold making 5. Molding processing 6. Surface treatment and printing 7. Quality inspection 8. Packaging and delivery

In acidic environments, the tin-plated layer of electrolytic tinplate can provide a certain degree of protection, but its acid resistance is limited. Strong acid environments may cause the dissolution and corrosion of the tin layer, thereby exposing the low-carbon steel substrate and further inducing corrosion.
