Tin Coated T1-T5 DR7 Temper 2.8/2.8 ETP Consumer and Industrial Packaging Electrolytic Tinplate Coil
Electroplated tin plate is a kind of product with complex production technology, strong technology, long manufacturing process, high quality requirements and high manufacturing difficulty. Electroplated tin plate not only has high strength, good formability, excellent corrosion resistance, strong weldability, bright appearance and other characteristics, but also has good printing coloring, coupled with the non-toxic tin plating layer, so electroplated tin plate is widely used in the food industry and the production of various containers, stamping products, packaging materials and other non-food industries.
Modern tinplate is usually made from cold-rolled, low carbon steel, which is meticulously coated with pure tin on both sides. This composite material combines the inherent strength and malleability of steel with the superior corrosion resistance, weldability, and visual appeal of tin. Tinplate is extensively used in various industries due to these advantageous properties.
Composition and Properties
1. Base Material:
- Cold-Rolled Low Carbon Steel: Provides the structural integrity and flexibility required for diverse applications.
2. Coating:
- Pure Tin Coating: Applied to both sides of the steel, enhancing corrosion resistance, improving weldability, and providing an attractive surface finish.
Industrial Applications
1. Food Industry:
- Cans and Packaging: Widely used for packaging food products such as vegetables, fruits, soups, and meats. Tinplate ensures the contents remain uncontaminated and preserved for long periods.
2. Beverage Industry:
- Gas-Containing Beverage Containers: Used for carbonated drinks, providing a strong barrier to maintain carbonation and prevent spoilage.
- Bottle Caps: Utilized in the production of secure and corrosion-resistant caps for glass and plastic bottles.
3. Aerosol Industry:
- Aerosol Cans: Ideal for packaging products like deodorants, hairsprays, and insecticides. The tin coating prevents the contents from reacting with the can, ensuring product stability.
4. Non-Food Packaging:
- Home Appliances: Employed in the manufacture of durable and rust-resistant components for appliances such as refrigerators and washing machines.
- Toys: Used in the production of metal toys, offering both durability and an attractive finish.
- Stationery: Commonly used for items like pencil cases and decorative tin boxes, combining practicality with visual appeal.
5. Engineering Materials:
- Construction Materials: Occasionally used in roofing and cladding applications, providing a weather-resistant and durable material.
- Automotive Components: Used for certain parts and accessories in vehicles, benefiting from the material’s strength and resistance to corrosion.
In summary, modern tinplate, crafted from cold-rolled, low carbon steel coated with pure tin, is a versatile and valuable material. Its combination of strength, malleability, and resistance to corrosion makes it suitable for a wide range of applications, particularly in the food and beverage packaging sectors, as well as in non-food packaging, home appliances, toys, stationery, and various engineering materials.
We are professional tinplate sheet coil manufacturer, located in Shandong province. We produce a line of tinplate sheet that is compliant with GB/T 2520-2000, JIS G3303-2002 and DIN EN 10203-1991 standards.

The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. |
|||||
|
a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. |

5. Surface of ETP
• Passivation types
• Sodium dichromate cathodic treatment (CE) or 311 process.
• Sodium bichromate impregnation (CP) or 300 process.
• Surface appearance
• It is determined by the surface appearance of the steel base and whether the tin coating is soft melted.
• Bright surface (B) : The original plate with a smooth surface with a very fine millstone pattern is coated with tin, and then the tin layer is soft melted to obtain a bright surface.
• Rough surface (R) : The original plate with a certain directional grinding stone pattern surface is plated with tin, and then the tin layer is soft melted to obtain a shiny surface.
Silver surface (S) : The original plate with a rough and dull surface is tinned, and then the tin layer is soft melted to obtain a glossy surface.
• Matte surface (M) : The matte surface is tinned on the original plate with a generally matte surface and then is not softenable.
