Prime Electrolytic Tinplate (SPTE) for Food & Beverage Cans - DR9 & T5CA Grade Corrosion Resistant

Our Prime Electrolytic Tinplate (SPTE) is a premium-grade, cold-rolled steel substrate uniformly coated with pure tin through a precise electrolytic process. Designed as the foundational material for high-integrity metal packaging, it is specifically engineered to meet the stringent demands of food and beverage containers, including vegetable cans, fruit preserves, meat, fish, and carbonated beverage cans. Characterized by its inherent metallic luster and exceptional barrier properties, this tinplate provides robust, long-term corrosion resistance against acidic and alkaline contents, ensuring product safety, extended shelf life, and preservation of flavor. Available in both coil and sheet forms with a wide range of customizable tempers and dimensions, it is the optimal choice for manufacturing two-piece draw-redraw (DRD) cans, three-piece welded cans, and easy-open ends.

• Prime Material Quality: Manufactured from superior MR-grade steel, ensuring consistent formability, weldability, and a flawless surface for printing and coating.

• Superior Corrosion Barrier: The electrolytic tin coating acts as a potent sacrificial layer, providing excellent resistance to internal chemical attack and external rust, crucial for long shelf-life products.

• Excellent Fabrication Properties: Offered in key industry tempers like DR9, T5CA, and T4CA, providing the ideal balance of high strength and ductility required for deep drawing (DI cans) and bodymaking.

• Versatile Surface Finishes: Available in Bright, Stone, Matte, and Silver finishes to suit different aesthetic needs and enhance adhesion for protective lacquers and high-quality lithographic printing.

• Broad Compatibility: Suitable for both traditional soldering and modern high-speed welding production lines, offering flexibility in can manufacturing processes.

Selecting our Prime Electrolytic Tinplate delivers operational efficiency and market confidence. Its consistent gauge and temper reduce material waste and tool wear, optimizing production yields. The material's excellent printability allows for vibrant, durable branding directly on the can surface. Furthermore, its 100% recyclability supports sustainable packaging initiatives, while its superior strength-to-weight ratio minimizes transportation costs. Compliance with international standards (EN10202, ASTM, JIS) guarantees global acceptability and performance reliability.

Q1: What is the difference between BA (Bright Annealed) and CA (Continuous Annealed) tinplate?

A1: BA tinplate undergoes batch annealing, resulting in a brighter, more reflective surface and softer temper, ideal for certain deep-drawn applications. CA tinplate is processed through continuous annealing lines, offering more uniform mechanical properties and a slightly harder temper, preferred for high-speed, consistent forming in beverage can production.

Q2: Why is DR9 temper commonly specified for beverage cans?

A2: DR9 (Double Reduced, 90% reduction) temper indicates a high-strength, thin-gauge material achieved by a second cold-rolling pass. It provides the necessary rigidity and pressure resistance for carbonated beverage cans while allowing for significant lightweighting and material savings.

Q3: Can you supply tinplate with specific dimensions for our existing tooling?

A3: Yes, we offer extensive customization. You can specify exact width (e.g., 870mm, 925mm), length for sheets, or inner diameter for coils to match your production line requirements seamlessly.

Q4: Do you provide pre-lacquered or printed tinplate?

A4: While we primarily supply the base prime tinplate, we can coordinate with partner facilities to provide finished, printed sheets or coils. We recommend discussing your specific decoration needs with our technical sales team.

Q5: What is the lead time for a typical order?

A5: For standard specifications, the delivery time is typically negotiated and can range from 15-25 days after order confirmation and payment. This is supported by our large monthly supply capacity of 50,000 MT.

Tinplate is applied to various containers such as food, beverage, artistic containers and electric parts.

Excellent paint adhesion makes itself the most suitable material for making food can, crown, artistic can and general can with painting.
