The coating finish of electrolytic tinplate is high, and the surface of the tin layer after electrolysis treatment is smoother and brighter, which is conducive to subsequent printing, spraying and other fine processing. The tin layer of non-electrolytic tinplate is relatively thick and is usually not suitable for detailed processing.

The anti-rust performance of tinplate depends first on the quality and thickness of its tin plating. During the production process, the thickness of the tin layer is generally controlled in the range of 1.5g/m² to 15g/m², depending on the purpose of the can and the acidity and alkalinity of the food.

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

According to laboratory measurements and literature data, the thermal conductivity of tinplate sheet is usually between 50-60 W/m·K. The specific value depends on factors such as the composition of the steel base, the thickness of the tin layer, and the manufacturing process.
