ETP Tin Coated Used For Packaging Foodstuffs And Beverages
Tinplate Steel Coil For Aerosol Containers
1. Introduction
Tinplate refers to steel sheets or coils that have been coated with a thin layer of tin through a process called electroplating or hot-dip coating. The coating of tin helps improve the steel's resistance to corrosion, enhances its formability, and provides a smooth surface ideal for various applications.
Tinplate is usually produced by taking low-carbon steel or mild steel and coating it with a thin layer of tin, which acts as a protective barrier against rust, corrosion, and environmental factors. The thickness of the tin coating typically ranges from 1 to 12 microns, depending on the application and requirements. Tinplate is available in various grades and types, which influence its characteristics like strength, flexibility, corrosion resistance, and printing ability.
2. Tinplate characteristics
- Corrosion Resistance: Tinplate offers excellent resistance to corrosion due to the protective layer of tin. The tin coating prevents water, moisture, and other corrosive elements from coming into direct contact with the underlying steel.
- Formability: Tinplate has good formability, which makes it suitable for deep drawing, pressing, and other shaping processes. This is crucial for applications where the material needs to be bent or shaped into complex forms.
- Smooth Surface: The smooth, shiny finish of tinplate makes it ideal for printing and decoration, and it enhances its visual appeal, which is especially important in packaging and consumer products.
- Lightweight: Tinplate is relatively lightweight compared to other metals, which is an advantage in many packaging applications, such as cans.

| The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. |
| a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. |
