T1-T5 Temper 2.8/2.8 Coating Tinplate Coil used for Beverage Tinplate Can ETP Plate
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.

2. Applications of Different Types of Tinplate
1. Food and Beverage Packaging:
- The most common use for tinplate is in the packaging industry, particularly for food cans (e.g., fruits, vegetables, soups) and beverage cans (e.g., sodas, beer). The tin layer prevents the steel from corroding, and the non-reactive surface keeps the food fresh.
2. Aerosol Cans:
- Aerosol containers for products like deodorants, hairsprays, and air fresheners use tinplate because it offers good corrosion resistance and strength to withstand internal pressure.
3. General Line Containers:
- Paint cans, oil containers, and other general-use packaging often use tinplate or TFS to protect the contents from environmental exposure while providing a durable exterior.
4. Bottle Caps and Closures:
- Tinplate is commonly used for crown caps, twist-off caps, and screw caps for bottles because of its formability and corrosion resistance.
5. Decorative Packaging:
- Tinplate is also used for premium decorative packaging like cookie tins, tea containers, and gift boxes due to its strength, aesthetic qualities, and ability to be printed or embossed easily.

| 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℃. |

| Remarks | The internal control is set at-0.002mm of the thickness of the contract order. The measurement value of the midpoint in the width direction of the strip shall prevail. | The internal control sets the thickness of the contract order thickness. The measurement value of the midpoint in the width direction of the strip shall prevail. | The internal control is to set the thickness of the contract order at +0.003mm, and the measured value at the midpoint of the strip width direction shall prevail. |
| 1. The thickness of S1, S2, S3 surface and M surface shall be measured by the flat thickness meter. (The matt surface will be higher than the actual measurement due to surface roughness.) |
