Food Grade Electrolytic Tinplate Sheet in Coil ETP TFS 1.1–11.2g/m²

1．Product Overview

Food grade electrolytic tinplate sheet in coil is widely used for food packaging, beverage cans, aerosol cans, chemical cans, decorative metal containers, battery shells, and industrial packaging applications.

The product includes ETP and TFS materials with controlled tin coating, stable surface quality, and suitable forming performance for can-making and metal packaging production lines.

Different temper grades and coating combinations support stamping, drawing, bending, printing, lacquering, and container forming requirements.

2．Technical Solution

The product is manufactured by electrolytic coating technology on cold rolled steel substrate. Tin coating improves corrosion resistance, solderability, food compatibility, and packaging durability.

Temper grades from T1 to T5 and DR8 to DR9 support different hardness and forming performance requirements. Softer tempers are suitable for deep drawing and forming, while higher temper grades provide increased rigidity and panel strength.

Equal and differential tin coating options can be selected according to can structure, filling material, storage environment, and corrosion resistance requirements.

Surface finishes including bright, stone, silver, matte, mirror, and color printing support decorative packaging and downstream printing applications.

7．Advantages

• Electrolytic tin coating improves corrosion resistance and packaging durability.
• Multiple temper grades support forming, stamping, and rigidity requirements.
• Equal and differential tin coating options support different can structures and storage conditions.
• Thickness tolerance of ±0.01mm supports stable can-making performance and dimensional consistency.
• Bright, matte, mirror, stone, and printed finishes support decorative and industrial packaging applications.
• The 600–1050mm width range supports different can-making and slitting production lines.

8．How to Choose

• Choose T1 or T2 temper for deep drawing and higher forming requirements.
• Choose T3 or T4 for general food can applications.
• Choose T5, DR8, or DR9 when higher rigidity and thinner wall design are required.
• Choose higher tin coating such as 8.4 or 11.2g/m² for higher corrosion resistance and longer storage requirements.
• Choose differential coating when different inside and outside corrosion protection levels are required.
• Choose matte or stone finish for coating and printing applications.
• Choose mirror or bright finish for decorative packaging appearance.
