Product Introduction
Tinplate (ETP) is a high-quality electrolytic tin-coated steel widely used in the production of food cans, beverage cans, aerosol cans, and industrial containers. It combines the strength of steel with the corrosion resistance of tin, providing reliable protection for packaged products. With a smooth and uniform surface, it supports printing and coating processes, ensuring strong adhesion and a refined appearance. Its good formability allows efficient shaping and compatibility with high-speed production lines.
Backed by integrated processing capabilities, FANWO PACKING supplies tinplate in both coil and sheet forms, with flexible options in thickness, temper, and coating weight to meet diverse manufacturing requirements.

From Tinplate to Finished Food Cans
Cold Rolling
High-quality low carbon steel is cold-rolled to the required thickness, ensuring uniform mechanical properties and dimensional accuracy.
Stable rolling control helps deliver consistent material quality, making it easier to support downstream processes such as coating, printing, and forming in various metal packaging applications.
Annealing
During annealing, the steel is treated in either batch or continuous processes to improve ductility and formability. This makes the material more suitable for can body forming and shaping.
With controlled annealing, the material maintains stable performance and adapts more easily to subsequent processing.
Electrolytic Tin Coating
A thin layer of tin is applied to both sides of the steel sheet through an electrolytic process, creating a clean and uniform surface.
This step enhances corrosion resistance and supports food safety compatibility while providing a stable base for subsequent processes such as coating, printing, and forming.
Reflow Treatment
The tin-coated surface is heated to form a more even and refined finish.
This treatment improves visual appearance and enhances surface compatibility with subsequent processes, making the material better suited for later printing, coating, and forming without affecting its overall stability.
Surface Passivation
A chemical treatment is applied to the surface to prevent oxidation and maintain stability during storage and transportation.
This step helps preserve material condition and supports more consistent performance in subsequent processing, making the tinplate more reliable for different packaging applications.
Oiling
A light oil layer is applied to reduce friction and protect the surface from scratches during processing and handling.
This treatment helps maintain material condition and allows smoother feeding in downstream operations such as cutting, forming, and printing, supporting stable performance in metal packaging production.
Inspection & Finishing
The final product is inspected for thickness, coating weight, surface quality, and dimensional accuracy before delivery. Materials are then prepared in coil or sheet form according to customer requirements.
This step helps ensure consistent quality and makes the tinplate ready for use in various metal packaging applications.

FAQ
What is the difference between Tinplate (ETP) and Tin Free Steel (TFS)?
Tinplate (ETP) is coated with tin, offering better corrosion resistance and food safety performance. Tin Free Steel (TFS) uses chromium coating and is typically used for can ends or lids rather than can bodies.
Is your tinplate suitable for food packaging?
Yes, our tinplate meets food-grade requirements and can be used for food cans such as vegetables, fruits, meat, and milk powder. BPA-free coating options are also available upon request.
