Food-Safe Electrolytic Tin Plate & TFS with Enhanced Rust & Alkali Resistance for Can Ends
Product Description
This specialized Electrolytic Tin Plate (ETP) and Tin-Free Steel (TFS) product line is engineered for the critical application of manufacturing food can ends, lids, and bottom caps. Designed to meet rigorous food-grade safety standards, it provides superior, long-term resistance against both rust formation and corrosive alkaline contents commonly found in products like tomato paste, certain vegetables, and prepared meats. The precise electrolytic tin coating or chromium-based TFS coating acts as a robust, inert barrier, ensuring the metal does not interact with the food, thereby preserving flavor, color, and nutritional value. Available in key industrial thicknesses such as 0.16mm, 0.18mm, and 0.35mm, it offers the ideal combination of material strength for secure sealing and economic efficiency.
Features & Characteristics
-
Dual-Action Protection: Formulated to withstand both external environmental rust and internal corrosion from alkaline or acidic food substances, significantly extending shelf life.
-
Food-Contact Compliant: Manufactured from certified MR/SPCC steel with non-toxic coatings, ensuring absolute safety for direct food packaging applications.
-
Precision Gauge Consistency: Offered in tightly controlled thin gauges (0.15-0.46mm) to optimize material usage while maintaining the structural integrity required for safe can sealing and stacking.
-
Excellent Formability: Available in a spectrum of tempers (T1-T5, DR7-DR9) to facilitate complex stamping and forming processes for double-seaming ends without fracturing.
-
Superior Surface for Coating: The provided surface finishes (Matte, Stone, Bright) ensure excellent adhesion for protective internal lacquers and high-quality external lithographic printing.
Key Advantages
Implementing this resistant tinplate directly enhances canning line reliability and end-product safety. It minimizes the risk of container failure due to corrosion, protecting brand reputation. The material's lightweight nature reduces shipping costs, and its 100% recyclability supports corporate sustainability goals. Furthermore, the ability to customize the internal lacquer system (e.g., 202, 300, 401, 603 coatings) allows for tailored solutions for specific food types, from fruits to aggressive tomato-based products.

Frequently Asked Questions (FAQ)
Q1: What makes this tinplate specifically "alkali-resistant"?
A1: The resistance is achieved through a combination of the inherent properties of the tin or chromium coating and the application of specialized, food-grade internal lacquers (e.g., epoxy-phenolic). These are tested to withstand the chemical attack from alkaline foods, preventing corrosion and sulfide staining.
Q2: Which is better for my application, ETP or TFS?
A2: ETP offers excellent overall corrosion resistance and solderability. TFS provides superior paint/adhesive adhesion and outstanding resistance to sulfide staining. The choice depends on your specific food content, manufacturing process (welding vs. soldering), and internal coating requirements.
Q3: Can I order tinplate with a specific internal coating already applied?
A3: Yes, we offer pre-lacquering services. You can specify the internal coating type (e.g., 202 for chili sauce, 603 for fruits) based on your product's pH and characteristics, streamlining your production process.
Q4: What quality certification do you provide?
A4: We supply a Mill Certificate with each shipment, detailing the chemical composition, mechanical properties (hardness, temper), coating mass, and compliance with relevant standards. This serves as your material quality guarantee.
Q5: What information do you need to provide an accurate quotation?
A5: Please specify: Product name (ETP/TFS), thickness, temper, coating weight, dimensions (width, coil ID or sheet size), surface finish, quantity, and the intended food application to determine the best internal coating recommendation.
