ETP Tin Coated 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 typically crafted from cold-rolled, low carbon steel, meticulously coated with pure tin on both sides. This composite material synergizes the inherent strength and malleability of steel with the superior corrosion resistance, weldability, and visual appeal of tin. Such tinplate finds extensive applications across various industries, particularly in the food sector for cans and packaging. It also serves in non-food applications such as aerosol cans, bottle caps, gas-containing beverage containers, as well as in the manufacturing of home appliances, toys, stationery, and 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.

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.

8. APPLICATIONS 

Bottle Cap Tinplate

As is known, light can cause and accelerate oil oxidation, which reduces nutrition value of oil by destroying its vitamin A and D, and even more seriously, by generating harmful substances. And, oxygen in the air can also lead to food oil oxidation, resulting in decreased protein biomass and damaged vitamins. To avoid this, we have developed tinplate that has high opacity and excellent airtight seal, and can provide better protection for the contained oil, food, beverage, and so on. Hence, the oil tin can is ideal for packing lipids.

To provide the highest quality oil tinplate can, we implement rigid inspection on the whole process from material procurement to the final product delivery. In addition to strict monitoring on working procedures such as acid washing, reciprocal rolling, and degreasing, etc., our specialized personnel check our products through mechanical property tester and coating tester to ensure superior performance of our oil tin can. As a result, our oil tin can features strong corrosion resistance, high formability and easy welding, and you can thus feel secure in choosing our products.
