Electrolytic Tin Plate (ETP), or SPTE, represents a fundamental advancement in protective metal packaging. It consists of a low-carbon cold-rolled steel substrate that undergoes a precise electrolytic process, resulting in a uniform coating of pure tin on both surfaces. This product is specifically supplied in coil form, optimized for high-speed, automated manufacturing lines that produce two-piece beverage cans, food containers, and various industrial packaging solutions. The highlighted thicknesses—0.23mm, 0.32mm, and 0.33mm—are industry-proven gauges that provide an optimal balance between material strength for container integrity and economic efficiency. The tin coating's primary function is to offer sacrificial, long-term resistance against corrosion and rust, ensuring the packaged contents are shielded from degradation and the container maintains its durability throughout the supply chain.
Engineered Corrosion Defense: The electrolytic tin layer acts as a robust, sacrificial barrier, providing superior resistance to oxidation and chemical attack from both the environment and aggressive contents.
Precision Thickness Control: Offered in critical, industry-standard gauges like 0.23mm, 0.32mm, and 0.33mm, ensuring consistent performance, optimal material usage, and compatibility with high-speed stamping and drawing equipment.
High-Strength Material Base: Manufactured from prime MR/SPCC steel grades, available in a range of hardness levels (TS230-TH620), allowing selection based on required can rigidity and formability.
Versatile Surface Finishes: Available in Bright, Stone, Matte, Silver, and Rough Stone finishes to meet different aesthetic requirements and enhance adhesion for paints and lacquers.
Excellent Fabrication Compatibility: Designed for excellent weldability and formability, making it suitable for modern two-piece can manufacturing processes as well as three-piece welding lines.
Incorporating these tinplate coils into your production delivers significant operational benefits. The coil format enables continuous, high-volume processing with minimal stoppages, maximizing production line efficiency. The precise thickness and inherent strength contribute to lightweighting potential, reducing material costs and logistical expenses. Furthermore, the proven corrosion resistance minimizes the risk of container failure, protecting brand reputation and reducing waste. The material's 100% recyclability also aligns with sustainable packaging initiatives.

Q1: How do I choose between 0.23mm, 0.32mm, and 0.33mm thickness?
A1: The choice depends on your end-use. 0.23mm is often used for lighter-weight cans or ends, 0.32mm is a common standard for many food and beverage can bodies, and 0.33mm may be specified for added rigidity in larger containers or for products requiring higher internal pressure resistance.
Q2: How does the tin coating provide rust resistance?
A2: Tin is less reactive (more cathodic) than steel in many environments. The coating acts as a physical barrier and, if scratched, provides sacrificial electrochemical protection to the underlying steel, significantly slowing the corrosion process.
Q3: Can these coils be supplied with a protective internal coating?
A3: While we primarily supply the base tinplate, we can coordinate the application of custom internal lacquers (epoxy, phenolic) based on your specific product requirements (e.g., acidic foods, beverages).
Q4: What quality assurance do you provide?
A4: We provide full Mill Certification detailing chemical composition, mechanical properties, and coating metrics. Our production is compliant with international standards including JIS G3303, and we offer third-party inspection services from SGS.
Q5: What are the ordering requirements for customized widths?
A5: Custom widths within the 651mm-1030mm range are available. Please specify your exact required width (e.g., 894mm, 906mm) and the corresponding inner diameter (ID) for the coil. A minimum order quantity (MOQ) of 25 tons typically applies for custom specifications.
