T4 2.8 Prime Electrolytic Tinplate Sheet Coil for Food Canning

1．Product Overview

Prime electrolytic tinplate sheet coil is used for food cans, beverage cans, aerosol cans, cosmetic containers, paint cans, chemical cans, storage cans, battery shells, and stationery packaging.

The product is made from low carbon steel substrate with electrolytic tin coating on the surface. Tin coating improves corrosion resistance, solderability, and food packaging suitability, while different temper grades support forming, stamping, and can-making requirements.

2．Technical Solution

Electrolytic tinplate is produced by applying controlled tin coating on cold rolled steel substrate through an electrolytic plating process.

Tin coating options such as 1.1/1.1, 2.8/2.8, and 5.6/5.6 can be selected according to corrosion resistance, can type, filling material, and storage requirements.

Temper grades from T1 to T5 and DR8 to DR9 support different hardness and forming needs. Softer tempers are suitable for forming and drawing, while higher tempers are used when higher panel stiffness is required.

Surface options include bright, matt, and frosted finishes for different printing, lacquering, and can appearance requirements.

3．Specifications

4．Application

This tinplate sheet coil is suitable for food cans, beverage cans, aerosol cans, cosmetics cans, paint cans, chemical cans, storage cans, battery containers, stationery packaging, and general metal packaging products.

It is commonly used in can-making lines requiring stable coating quality, good surface appearance, and consistent forming performance.

5．Processing

The tinplate coil supports slitting, cut-to-length processing, printing, lacquering, stamping, forming, seaming, and can body production.

Bright, matt, and frosted surfaces can be selected according to printing and appearance requirements.

Standard seaworthy export packing protects the coil during long-distance shipment and container transportation.

6．Advantages

• Electrolytic tin coating supports corrosion resistance and packaging performance for can-making applications.
• Multiple tin coating options allow selection according to food type, chemical content, and storage conditions.
• Temper grades from T1 to T5 and DR8 to DR9 support different forming and stiffness requirements.
• Thickness range from 0.15mm to 0.50mm covers light packaging and stronger container applications.
• 508mm and 610mm coil ID options support standard tinplate processing and can-making equipment.
• Surface finishes including bright, matt, and frosted support printing, lacquering, and decorative packaging.

7．How to Choose

• Choose lower temper grades such as T2 or T3 when better forming performance is required.
• Choose T4 or T5 when higher stiffness is needed for can ends, covers, or stronger packaging structures.
• Choose DR8 or DR9 for applications requiring higher strength and reduced thickness design.
• Choose higher tin coating such as 5.6/5.6 for higher corrosion protection requirements.
• Choose bright surface for printed and decorative cans.
• Choose matt or frosted surface when specific appearance or coating adhesion requirements are needed.
• Confirm thickness, width, temper, tin coating, surface finish, coil ID, and final can-making process before production.
