Electrolytic Tinplate undoubtedly enjoys the pride of place as a packaging medium especially for food. It owes its unique position to its "nine layer sandwich structure", each of which contributes to its eminence as a packing material. The steel base provides the necessary strength and formability for can fabrication. The tin-iron alloy layer provides the bond between the steel and free tin layer. The free tin layer is not only responsible for the attractive bright finish and ease of solderability but is also non-toxic- a factor of vital importance in food packaging!
Electrolytic TinPlate: Composition
E.T.P. consists of five layers each of which performs a different role:
1. Steel Base: Provides stiffness to the material due to its thickness and mechanical strength. Its chemical composition imparts special properties to resist corrosion.
2. Iron-Tin Alloy: This is made up by the inter-metallic compound Fe-Sn2. Due to its electrochemical characteristics, it acts as a barrier against corrosion. For effective action, its continuity is more important than its quantity.
3. Metallic Tin: Tin has many advantages which have turned it into the most important element to protect steel used for cans; in many foods, it acts as a simple barrier against corrosion, improves weldability, it is an excellent base for lithographic printing and for applying lacquers. In tin-robbing foods, it acts as a sacrificial element.
4. Passivation Film: According to its nature, it makes it possible to improve the E.T.P.’s resistance to sulphiding, oxidation and rust. It is also a conditioner to improve the adherence of varnishes, inks, lacquers etc.
5. Oil Film: Protects the sheet from the humidity in the environment and makes easy to handle. It is applied using an electrostatic oiler on both sides of the sheet.

- Q:How is tinplate cut and formed into different shapes?
- Tinplate is cut and formed into different shapes through a process called stamping. In this process, the tinplate sheet is placed between two dies, a male and a female die, and pressure is applied to cut and shape the metal into the desired form. The dies have the desired shape engraved on them, and when pressed together, they cut through the tinplate and form it into the desired shape.
- Q:How does tinplate contribute to the presentation of jewelry?
- Tinplate is often used in the packaging of jewelry, such as boxes or containers, which enhances the presentation and adds an element of luxury. Its glossy and reflective surface provides a visually appealing backdrop for showcasing the beauty and intricacy of the jewelry inside. Additionally, tinplate offers excellent protection against corrosion and moisture, ensuring the longevity and preservation of the jewelry.
- Q:Can tinplate be used for food packaging?
- Yes, tinplate can be used for food packaging. It is a commonly used material due to its durability, resistance to corrosion, and ability to protect the contents from external contaminants. Tinplate is also easily recyclable, making it an environmentally friendly choice for food packaging.
- Q:What are the different surface finishes available for tinplate?
- There are several surface finishes available for tinplate, including bright, stone, matte, and lacquered finishes.
- Q:Can tinplate be used for coinage?
- No, tinplate cannot be used for coinage as it is not a suitable material for making coins.
- Q:How does tinplate handle exposure to gases and odors?
- Tinplate is known for its excellent resistance to gases and odors. It acts as a protective barrier, preventing the transmission of gases and odors into the contents it contains. This makes tinplate an ideal choice for packaging solutions, ensuring the integrity and quality of the products inside.
- Q:How does tinplate compare to tin-free steel in terms of properties and applications?
- Tinplate and tin-free steel have distinct properties and applications. Tinplate is steel coated with a thin layer of tin, making it corrosion-resistant, ductile, and ideal for applications requiring high aesthetic appeal, such as food and beverage packaging. On the other hand, tin-free steel lacks the tin coating but compensates with a polymer or metallic coating, offering enhanced strength and weldability. Tin-free steel finds application in various industries, including automotive, construction, and industrial packaging, where durability and cost-efficiency are prioritized over aesthetic requirements.
- Q:Can you tell me how to deal with the recycling of tinplate?
- General tinplate packaging waste, as long as the rust is not serious, can be converted into hardware products, to achieve the best use of materials. The consumption of tinplate in our country is relatively large (600 thousand tons / year), and 125 tons of tin packing waste can be recovered 1 tons of tin.
- Q:Can tinplate be used for confectionery packaging?
- Yes, tinplate can be used for confectionery packaging. Tinplate is a type of steel coated with a thin layer of tin, which provides excellent resistance to corrosion and is a safe material for food packaging. It is commonly used for confectionery tins and cans due to its durability, protective properties, and ability to maintain the freshness and quality of the product.
- Q:What are the different types of tin coatings used on tinplate?
- There are primarily three types of tin coatings used on tinplate: electrolytic tinplate (ETP), tin-free steel (TFS), and black plate. ETP is the most common and consists of a thin layer of pure tin electroplated onto the steel substrate, providing excellent corrosion resistance and food compatibility. TFS, on the other hand, is a steel substrate coated with a layer of chromium oxide or chromium oxide and polymer, offering comparable properties to ETP but without the use of tin. Lastly, black plate refers to uncoated steel that can be further processed or coated as per specific requirements.
