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

Common inner coating materials include epoxy resin, polyester, polyurethane and acrylic resin. These coating materials have good chemical resistance, heat resistance and adhesion, and can effectively ensure the safety and quality of the substance in the can.

Tin cans have excellent anti-corrosion properties, sealing properties and durability, and are widely used in food, chemical, pharmaceutical and electronic industries. However, tin cans also have disadvantages such as higher cost, weight, and susceptibility to chemical corrosion.

Metal materials such as tin-plated steel sheets and aluminum are suitable for high-end candy tin boxes, with good protection and aesthetics; plastic materials such as polyethylene and polypropylene are suitable for economical candy tin boxes, with the advantages of low cost and good processability.
