Rust Resistance Electrolytic Tinplate with Good Preservation for Metal Food Packaging

1. Good anti-rust performance: The electrode potential of tin is higher than that of iron, and its chemical properties are stable. It can effectively prevent the steel substrate from rusting. Even if the tin-plated layer has tiny pores or is scratched, as long as the tin layer is not completely destroyed, it can still protect the steel base to a certain extent.
2. Strong corrosion resistance: After the soft solution treatment or passivation treatment after electroplating, a tin alloy layer and a tin oxide layer can be generated, which further reduces the pores, enhances the corrosion resistance, and can well resist the erosion of acid, alkali and other substances in food.
3. Non-toxic and harmless: Tin itself is non-toxic and will not pollute food. It meets the hygiene requirements of food packaging and can be directly in contact with food.
4. High strength: With low-carbon steel as the substrate, it has high strength and can withstand certain pressure and impact. It is not easy to deform and damage during the production, transportation and storage of food packaging.
5. Good ductility: It is easy to process and shape, and can be made into food packaging containers of various shapes, such as cans, cans, etc.
6. Good sealing: It can cooperate well with other materials to achieve a good sealing effect, prevent food from contacting with external air, moisture, etc., and maintain the freshness and quality of food.
