Tinplate sheets are high-quality cold-rolled low-carbon steel sheets coated with a thin layer of tin to provide excellent corrosion resistance, formability, and printability. This product range (0.14-0.50mm) is widely used in food packaging, industrial containers, and general packaging applications.

Manufactured from MR, SPCC, Q195L, and S08AL base steel grades, these tin coated steel sheets are available in coil or cut sheet form. With multiple temper grades (T1-T5, DR7-DR9) and surface finishes such as bright, stone, and lacquered gold/rose gold, they are designed to meet diverse packaging and forming requirements.

Food Packaging

• Beverage cans
• Milk powder cans
• Fruit cans
• Tomato paste cans
• Edible oil containers

Industrial Packaging

• Paint cans
• Chemical containers
• Lubricant tins
• Aerosol cans

General Packaging

• Cookie tins
• Gift boxes
• Stationery metal boxes
• Decorative packaging (rose gold / lacquered finishes)

Tinplate works by applying a thin tin coating onto a steel base through an electroplating process:

1. Cold-rolled steel is cleaned and prepared
2. Tin layer is electro-deposited on both sides
3. Surface is passivated to prevent oxidation
4. Oil or lacquer coating is applied for protection
5. Material is cut into coils or sheets for forming

The tin layer acts as a barrier between steel and external environment, preventing rust while maintaining food safety and durability.

When selecting tinplate sheets, consider the following:

• Thickness: 0.14-0.20 mm for light cans, 0.20-0.50 mm for industrial cans
• Temper grade: T1-T3 for easy forming, DR8-DR9 for deep drawing applications
• Coating weight: Higher coating (5.6/5.6 or above) for corrosive environments
• Surface finish: Bright for printing, stone/matte for industrial use, gold lacquer for decorative packaging
• Application type: Food-grade requires MR steel and certified coating standards

A1: It is mainly used for food cans, chemical containers, and decorative metal packaging due to its corrosion resistance and printability.

A2: Yes, MR-grade tinplate with proper coating meets international food safety standards such as JIS G3303 and EN10202.

A3: T1-T3 grades are softer and easier to form, while DR8-DR9 are harder and used for deep drawing and high-strength packaging.

A4: Yes, its smooth surface allows high-quality printing, varnishing, and decorative coatings.

A5: Common options include equal coating (e.g., 2.8/2.8, 5.6/5.6) and differential coating for corrosion protection optimization.
