BA EPT 2.8/2.8 T5/DR7 Electrolytic Tin Coated Plate Coils Used For Aerosol And Beverage Cans

1. Introduction

• What is tinplate?

• Tinned steel sheet referred to as tinplate, commonly known as tinplate, is a product made of tinning on a thin mild steel plate. The tin plate produced by the hot dip process is called the hot dip tin plate, and the tin plate produced by the electroplating process is called the electroplated tin plate.

• Because about 98~99.8% of the weight of the tin plate is steel, it is a coated steel variety that belongs to metallurgical products.

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. Tinplate characteristics

Advantages of Food Cans

Hygienic: Provide excellent and non-toxic barrier properties to protect food products from

impurities, bacteria, moisture, light, and odours.

Safe: Low weight and high strength make food cans easy to ship and store .

Eco-friendly: Offer 100% recyclability; and significant cost benefits compared with aluminum.

Application Records:

1. Food and Beverage Cans:

- Grade Requirements: Tinplate used for food cans must have a thin, uniform tin coating that provides excellent corrosion resistance. The surface finish should be smooth to avoid any contamination of the contents, and the material must be resistant to acids, alkalines, and moisture.

- Material Properties: For deep drawing and stamping, food can grades of tinplate are typically made from low-carbon steel, which offers high formability. The material must also meet food safety standards, ensuring that there are no harmful reactions between the tinplate and the food inside the can.

- Typical Grades: Common grades used in food canning are T1 and T2 tinplate, which are characterized by high ductility and low carbon content.

2. Aerosol and Beverage Cans:

- Grade Requirements: Tinplate used for beverage and aerosol cans must have high strength and be able to withstand internal pressure without deforming. It must also be resistant to corrosion and rust in environments containing liquids and gases.

- Material Properties: This grade of tinplate must possess excellent formability for deep drawing processes to create the cylindrical shape of cans. The tin coating must be uniform and sufficiently thick to provide a barrier to corrosion.

- Typical Grades: Grades such as DR8 (Deep Drawing) or DR9 are commonly used in beverage and aerosol cans. These grades provide high formability and strength.

3. Packaging for Non-Food Products:

- Grade Requirements: For packaging non-food products, such as paint cans or pet food cans, tinplate must have good resistance to chemicals and moisture. It also needs to offer adequate strength to hold the contents securely.

- Material Properties: These tinplates may be coated with additional layers, such as lacquers or varnishes, to provide enhanced protection. The coating needs to be durable enough to prevent damage during transportation or storage.

- Typical Grades: For non-food packaging, grades such as T3, T4, or T5 may be used, with varying levels of tensile strength and formability depending on the application.

4. Automotive Parts and Components:

- Grade Requirements: Automotive applications require tinplate that can withstand harsh environments and high levels of stress and corrosion. The tin coating must provide long-lasting protection against rust, especially in parts exposed to the weather and undercarriage.

- Material Properties: The tinplate used in automotive parts must have high tensile strength and impact resistance. It must also be highly formable to allow for the creation of complex shapes and designs.

- Typical Grades: Automotive applications may use higher strength grades such as SPCC (cold-rolled steel) with a heavier tin coating to improve durability and resistance.

5. Decorative Applications:

- Grade Requirements: For decorative products like signs and gift tins, tinplate must have a smooth, shiny surface that is suitable for printing or embossing. The material must also be resistant to scratches and dents to maintain its aesthetic appearance over time.

- Material Properties: These products often require a more decorative finish, with a thinner tin coating that provides aesthetic appeal without the need for heavy-duty protection.

- Typical Grades: DT1 (decorative tinplate) is often used for these applications, as it offers excellent surface quality and printability.
