The coating of tinplate is tin, while the coating of TFS is chromium. This is the most significant difference between the two. The anti-corrosion performance of tin mainly relies on its chemical inertness, while chromium relies more on its chemical stability and the protection of the oxide film.

High-quality electrolytic tinplate sheet should have a high-quality low-carbon steel substrate and a pure tin-plated layer: through composition analysis and surface inspection, ensure the purity and uniformity of the raw materials.

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.

with the advancement of technology and changes in market demand, aluminum gradually replaced tinplate sheet and became a new generation of packaging material. This article will explore in detail the reasons, advantages and impact of aluminum replacing tinplate sheet on related industries
