High-quality electrolytic tinplate sheet should have a high-quality low-carbon steel substrate and a pure tin-plated layer: through composition analysis and surface inspection, ensure the purity and uniformity of the raw materials.
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.
Use ink with excellent anti-corrosion performance during the printing process to improve the corrosion resistance of tinplate printed products. Anti-corrosion ink has good chemical corrosion resistance and weather resistance, and can provide long-lasting protection.
