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.

FAQ of Lacquered Tinplate for Metal Packing ETP sheet

How long does it take to get the product if i place an order?

With the process of your requirements,we will pack and deliver in 3-7 days.If it is by sea shipment,it will take 15-45 days depending on different locations.

Q: Can tinplate packaging be used for automotive products?: Yes, tinplate packaging can be used for automotive products. Tinplate is a durable and corrosion-resistant material, making it suitable for protecting automotive components such as spare parts, lubricants, and chemicals. Additionally, tinplate packaging can be customized to meet specific requirements, ensuring the safe transportation and storage of automotive products.

Q: How is tinplate coated?: Tinplate is coated through a process called electrolytic tinning. In this process, a thin layer of tin is electroplated onto the surface of steel sheets or strips. The steel is immersed in an electrolyte bath containing tin salts, and an electric current is passed through the bath. This causes the tin to deposit onto the steel surface, creating a protective coating that prevents corrosion and enhances the appearance of the tinplate.

Q: What are the advantages of using tinplate for packaging?: Tinplate offers several advantages for packaging. Firstly, it provides excellent protection against moisture, air, and light, which helps in preserving the quality and freshness of the packaged product. Secondly, tinplate is highly durable and can withstand rough handling during transportation and storage. It also offers resistance against corrosion, ensuring the longevity of the packaging. Additionally, tinplate is easily recyclable, making it an environmentally friendly choice. Lastly, tinplate can be shaped into various sizes and designs, allowing for attractive and customized packaging options.

Q: Can tinplate be recycled?: Yes, tinplate can be recycled. It is a highly recyclable material that can be melted down and reused to make new tinplate products. Recycling tinplate helps to reduce waste and conserve resources.

Q: What are the advantages of using tinplate for aerosol cans?: Some advantages of using tinplate for aerosol cans include its durability, corrosion resistance, and ability to maintain product quality. Tinplate cans offer a longer shelf life for aerosol products as they prevent air and moisture from entering the can, ensuring the product remains fresh and effective. Additionally, tinplate cans are lightweight, making them convenient for transportation and storage. They are also recyclable, contributing to sustainability efforts.

Q: Can tinplate be used for packaging of frozen foods?: Yes, tinplate can be used for packaging of frozen foods. Tinplate is known for its excellent durability, corrosion resistance, and ability to withstand extreme temperatures. These qualities make it suitable for packaging frozen foods as it helps to maintain the integrity and freshness of the food during storage and transportation.

Q: What are the different ways to seal tinplate cans?: There are several methods commonly used to seal tinplate cans. These include double seam closure, soldering, adhesive bonding, and welding. Double seam closure is the most widely used method, where the can's lid and body are mechanically interlocked and sealed using pressure and rollers. Soldering involves melting a metal alloy to create a tight seal between the lid and body. Adhesive bonding uses specialized adhesives to bond the lid and body together. Welding involves fusing the lid and body using high heat to create a strong and permanent seal.

Q: What are the different types of tinplate surface treatments?: The different types of tinplate surface treatments include electrolytic tinplate (ETP), tin-free steel (TFS), and blackplate.

Q: How does tinplate packaging contribute to brand recognition?: Tinplate packaging contributes to brand recognition by offering a distinctive and visually appealing presentation of the product. The use of tinplate materials allows for unique designs, vibrant colors, and intricate details that can catch the attention of consumers. This eye-catching packaging helps to create a lasting impression on customers, making them more likely to remember and recognize the brand. Additionally, the durability and premium feel of tinplate packaging can enhance the perceived value and quality of the product, further strengthening brand recognition and loyalty.

Q: How is tinplate coated with water-based paints?: Tinplate is coated with water-based paints using a process called coil coating. In this process, the tinplate is cleaned and then coated with a primer layer, which helps in improving adhesion. After the primer layer, multiple layers of water-based paints are applied using rollers or spray techniques. These layers are then dried and cured to form a strong and durable coating on the tinplate surface.
