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.

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.
