Electrolytic Tinplate Coil Used For Food Can Manufacturing ETP BA T3 2.8/2.8 coating

Electrolytic Tinplate Coil Tin Mill Products for Various Packaging and Industrial Needs

1. Introduction

Tin mill products include electrolytic tinplate, and electrolytic chromium coated steel (also referred to as tin free steel or TFS), and Black Plate. Tinplate is a thin steel sheet coated by tin, while TFS is an electrolytic chrome plated steel consisting of a thin layer of chromium and a layer of chromium oxide deposited on the steel base. The coating gives both of them a beautiful, metallic luster as well as excellent properties in corrosion resistance and paintability.

We are the professional manufacturer in China with advanced technical equipments, first class inspection devices and substantial experience in production. It possesses integrated process lines including smelting, hot rolling, cold rolling and coating. The product catalogue covers ETP and TFS with an annual output over 1 million tons. Our tin mill products are widely sold and used throughout the world in application of packaging of food, beverage and industrial goods and enjoy high reputation in the international market. 

2. Features of ETP Products

• Excellent Corrosion Resistance

By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents.

• Excellent Paintability & Printability

Printing is beautifully finished using various lacquers and inks.

• Excellent Solderability & Weldability

TIN PLATE is widely used for making various types of cans by soldering or welding.

• Excellent Formability & Strength

By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming.

• Beautiful Appearance

Electrolytic ETP is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.

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. Usage Precautions for ETP

• As ETP is covered by soft metallic tin coatings, due precautions should be taken not to cause scratches by rough handling or vibration during transportation.
• Paintability, printability, solderability, and mechanical properties of ETP tend to 收deteriorate as time elapses after production. Use as soon as possible after delivery.
• Although ETP has excellent corrosion resistance, it tends to rust in a humid atmosphere. Use as soon as possible after unpacking.
• Tin is dissolved by a strongly alkaline solution. When using ETP for making cans for alkaline contents, paint the internal surface.
• As contents that contain sulfur cause blackening of the ETP surface, paint the internal surface.

8. APPLICATIONS 

Modern industrial tinplate is usually a cold-rolled, low carbon sheet coated with commercial pure tin on both sides, which combines the strength and formability of steel with the corrosion resistance, weldability and appearance of tin. Tinplate is widely used in the food industry and a variety of containers, stamped products, packaging materials for non-food industry, such as food cans, spray cans, bottle caps, gas containing beverage cans, packaging materials and non-packaging materials (home appliances, toys, stationery, engineering).

Tinplate canned food, except few light color fruit and canned fruit, mainly adopts interior painted empty cans for improved corrosion resistance of containers. Under the electrochemical action of metal, a small quantity of iron dissolves out of enamel cans and exists as ferrous iron in the sealed canned food, ranging from 1ppm to 10 ppm, which is easy for people to absorb. Provided that there is 5ppm iron in every 350ml tinplate can, then each can of food can provides 1.75mg iron, which is about one tenth of 18mg daily iron intake by human body. In case of rich vitamin C contained in the canned fruit and vegetable juice, iron will be easier for assimilating. That is why this food tinplate can is so widely adopted for packaging food.

Apart from food deterioration, light can also cause changes of protein and amino acid. Even vitamin C tends to react with other food ingredients when exposed to light, leading to great nutrient loss. Research and analysis results show that vitamin C loss of glass bottled milk is 14 times higher than that of milk packed in dark bottles. Additionally, light can also bring oxidative off-flavors to milk, which results in cracking of nuclide and methionine, etc. and nutrition loss. In light of this, we have created the food tinplate can with high opacity, which accomplishes the highest vitamin retention.

9. Packing and Marking

Offers coils and sheets, coil packed in a vertical form or a horizontal.

A label that indicates the manufacturing history is affixed to the outside of the packaging. In addition, a service card is contained inside.
