Deep Drawing Food Can Electrolytic Tinplate Coil The Ideal Choice For Durable Packaging Solutions
1. Introduction
1. What's Tinplate?
Tinplate, also known as , refers to the cold rolled low carbon thin steel sheet with both sides coated with commercial pure tin, which primarily functions to prevent corrosion and rust. The tinplate incorporates steel rigidity and mouldability with tin corrosion resistant property, weldability and beauty, achieving strong corrosion resistance, non-toxicity, high strength and high malleability. It has wide applications in many manufacturing processes and industries of packaging, construction and domestic appliances.
2. Properties
A. Tinplate is characterized by its thin gauge, which is between 0.13mm and 0.49mm.
B. Tinning of the tinplate is achieved in a continuous electrolytic process.
3. Advantages
In addition to thin gauge, the tinplate also boasts mechanical properties with a wide range from 230 to 620MPa. Hence, it suits the needs in multiple forming processes and various industries.
The tinplate is available in varied surface finishes, with three different levels of roughness.
Like other steel, tinplate is easy for recycling in line with environmental protection requirements.
Also, with high opacity, and excellent sealing property, tinplate provides ideal protection for food, beverage, and other substances when made into packaging containers.
4. Applications
Particularly suitable for use in the packaging industry, tinplate can also be applied in the following areas.
In the home: cake tins, gas canister components, etc
In the fast food restaurant: coffee tins, cola tins, etc
Electrical and electronic equipment: batteries, electrical components, etc
Automotive components: cylinder head gaskets, oil filters, etc
Building trade: false ceiling rails, space bars for double glazing, light reflectors, radiator fins, reinforced tape, etc
Excellent Corrosion Resistance
By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents.
Excellent Paintability & Printability
Printing is beautifully finished using various lacquers and inks.
Excellent Solderability & Weldability
TIN PLATE is widely used for making various types of cans by soldering or welding.
Excellent Formability & Strength
By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming.
Beautiful Appearance
Electrolytic ETP is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.

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℃. |

Typical Applications including:
Consumer Packaging and Industrial Packaging
TINPALTE
ETP is primarily used for packaging foodstuffs and beverages, but it is also used in containers for oils, grease, paints, polishes, chemicals and many other products. Aerosol containers and caps and closures are also made from ETP.
TFS
TFS are most frequently used for can tops, screw and lug caps, snap and press-on closures and shallow-drawn food cans.
in Electronics
– Electrodes, Cable tape, Magnetic screen covers, etc.
in Engineering
– Automotive oil filters, Automotive air filters, Gaskets, etc.
in Construction
– Gas meter internal components, Heat exchangers, etc.
Our food tinplate can offers a good source of iron for its users. Tinplate canned food, except few light color fruit and canned fruit, mainly adopts interior painted empty cans for improved corrosion resistance of containers. Under the electrochemical action of metal, a small quantity of iron dissolves out of enamel cans and exists as ferrous iron in the sealed canned food, ranging from 1ppm to 10 ppm, which is easy for people to absorb. Provided that there is 5ppm iron in every 350ml tinplate can, then each can of food can provides 1.75mg iron, which is about one tenth of 18mg daily iron intake by human body. In case of rich vitamin C contained in the canned fruit and vegetable juice, iron will be easier for assimilating. That is why this food tinplate can is so widely adopted for packaging food.
