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.

In food packaging, the thickness of the tinplate sheet is directly related to the sealing performance and durability of the packaging. Standard tinplate sheets (0.20mm to 0.30mm) are often used in food cans and beverage cans, which can ensure both sealing and packaging strength.

In the US market, the price of electrolytic tinplate sheet is usually calculated per ton. According to recent market data, the price of electrolytic tinplate sheet in the US market is roughly between $1,500 and $2,000 per ton.

The biggest feature of electrolytic tinplate sheet is its excellent corrosion resistance. The tin plating layer can effectively isolate air and moisture, prevent oxidation reactions of the substrate, and extend the service life of the material.

Common defects of electrolytic tinplate sheet are: 1. Pinholes 2. Blisters 3. Cracks 4. Delamination 5. Color difference
