Electrolytic tinplate sheet, also known as electroplated tin iron, is a composite material with a layer of tin evenly plated on the surface of a thin steel plate.

The canning industry, especially the production of food and beverage cans, has extremely high requirements for the corrosion resistance of packaging materials. Tinplate sheet is endowed with excellent anti-corrosion properties due to the tin layer on its surface.

Manufacturing process of tinplate sheet: 1. Manufacturing of base steel sheet 2. Annealing and surface treatment 3. Tin plating process 4. Passivation treatment 5. Surface coating 6. Cutting and forming

The use of metal materials has a history of thousands of years worldwide, but the emergence of specific metal materials such as tinplate sheet can be traced back to Europe in the 16th century. Tinplate sheet originated from human demand for metal anti-corrosion treatment.

Manufacturing process of aerosol cans: 1. Preparation of tinplate sheets 2. Shearing and forming 3. Rolling and welding of cylindrical can bodies 4. Stamping and forming of can bottoms and can tops 5. Assembly of can bodies, can tops and can bottoms 6. Coating and surface treatment 7. Valve installation 8. Air tightness and pressure resistance testing 9. Filling and packaging

Advantages of tinplate packaging: 1. Excellent anti-corrosion performance 2. Good strength and toughness 3. Excellent airtightness and freshness 4. Recyclability and environmental protection 5. Excellent printing and decoration effects 6. Processing flexibility

The common manufacturing material for cookie tin packaging is tinplate, which not only has good mechanical strength and corrosion resistance, but also can provide excellent decorative effects for the can body.

Factors affecting the quality of tinplate: 1. The quality of the base steel plate 2. The uniformity and thickness of the tin plating layer 3. The bonding strength of the tin layer 4. Surface finish 5. The purity and tin damage of the tin layer

if the food in the can is highly acidic or the food is stored for too long, in some extreme cases, tin may dissolve in trace amounts. Even so, the amount of tin dissolved is usually very small and not enough to pose a threat to human health.

The main uses of electrolytic tinplate: 1. Recycling and purification of metallic tin 2. Recycling and reuse of iron substrates 3. Providing high-quality surface treatment processes 4. Environmentally friendly treatment of waste tinplate 5. Application in metal recycling 6. Reducing energy consumption 7. Producing high-purity tin products 8. Prolonging resource life and reducing mineral mining
