Tin Coated T1-T5 DR7 Temper 2.8/2.8 ETP Consumer and Industrial Packaging Electrolytic Tinplate Coil

1. Introduction

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. Currently, our tinplate is extensively used for packaging food, beverages, paint, oil, aerosols, and other everyday items. It is also used for bottle caps, auto parts, and batteries.

2. Features of ETP Products

The characteristics of the tin plate are largely determined by the characteristics of the tin.

• Tin is a silver-white metal with a light blue color, atomic weight 118.7, specific gravity 7.28, melting point 2320C in the atmosphere does not change color, chemical properties are also very stable. The tin plate can keep the metallic luster of the tin for a long time.
• Tin is a soft metal, so when tin plates are processed to make cans, the tin layer will not crack and fall off.
• Tin compounds are non-toxic, and when a small amount of tin is dissolved in food, it has no adverse effects on the color, taste, nutritional value of food and human health.
• Tin has good brazing properties, so the steel plate is easy to solder after tin plating, and it is easy to process when tin plates are used to make cans and other containers.
• The shape of the tin plate is smooth and bright like a mirror, and it is easy to paint and print.

4. Product Standard

• ETP

ETP orders are placed with Baosteel in accordance with Q/BQB 450-2009 standard which uses in a non-equivalent to JIS G 3303:2008, DIN EN 10202:2001, EN 10203 standards.

• TFS

TFS orders are placed with Baosteel in accordance with Q/BQB 455-2009 standard which uses in a non-equivalent to JIS G 3315:2008, DIN EN 10202:2001, EN 10203 standards.

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.
