High-Strength TH580 Electrolytic Tin Plate (ETP) for Durable Food Cans & Aerosol Containers

High-Strength TH580 Electrolytic Tin Plate (ETP) for Durable Food Cans & Aerosol Containers

Product Description

Our Electrolytic Tin Plate (ETP), also known commercially as SPTE, represents the pinnacle of material engineering for metal packaging. This product involves coating a cold-rolled, low-carbon steel substrate with a precise layer of pure tin through an electrolytic process. Designed to meet rigorous international standards, it is the material of choice for manufacturing high-integrity food cans (for tuna, sardines, fruits, vegetables), aerosol containers, paint cans, and general-line packaging. The TH580 hardness grade signifies a high-strength variant, offering exceptional durability for demanding forming processes while maintaining excellent barrier properties, ensuring product safety and extended shelf life.

Features & Characteristics

• Superior Material Integrity: Produced from prime steel grades (MR, SPCC) under continuous annealing (CA), ensuring consistent metallurgical properties.

• High-Strength Option: The TH580 hardness grade provides enhanced resistance to deformation, ideal for thinner gauges that require high structural rigidity in the final container.

• Exceptional Barrier Protection: The inert tin coating offers excellent defense against corrosion, oxidation, and sulfide staining, protecting sensitive contents.

• Superior Decorative Finish: Provides a brilliant, solderable metallic base that is perfect for high-quality offset printing (CMYK/PMS) and lacquering, enabling vibrant brand artwork.

• Excellent Fabrication Performance: Available in a range of tempers (T1-T5, DR7-DR9) to offer optimal formability, weldability, and deep-drawing capabilities for complex can shapes.

Key Advantages

Utilizing our Electrolytic Tin Plate translates into reliable and efficient packaging production. Its strength allows for lightweighting (using thinner gauges) without sacrificing can integrity, reducing material and logistics costs. The material is 100% recyclable, supporting circular economy goals. Furthermore, its compatibility with high-speed manufacturing processes like welding and stamping ensures high production yields and consistent quality for OEM and ODM projects.

Frequently Asked Questions (FAQ)

Q1: What is the significance of the TH580 hardness designation?

A1: TH580 indicates a high-strength grade with a tensile hardness of approximately 580 MPa. It is specifically engineered for applications where superior rigidity and resistance to deformation are required, often allowing the use of thinner material without compromising can performance.

Q2: Can you provide material for both welded and soldered can seams?

A2: Yes. Our ETP is formulated for excellent weldability in modern canning lines. Specific tempers and coatings also maintain excellent solderability for traditional manufacturing methods or specialized applications.

Q3: Do you offer customized printing directly on the tinplate sheets?

A3: Absolutely. We provide professional offset printing services using CMYK or Pantone (PMS) color systems directly onto the plate according to your provided artwork, streamlining your production process.

Q4: What is your quality assurance process?

A4: We adhere to strict international standards (JIS, DIN, ASTM). Each batch is accompanied by a Mill Certificate detailing chemical composition and physical properties. We implement rigorous in-process controls to ensure consistency in coating, temper, and surface quality.

Q5: What are the standard payment and delivery terms?

A5: Our standard minimum order quantity (MOQ) is 25 tons. Payment is typically via T/T, and delivery time is negotiated based on order volume and specifications, with a robust monthly supply ability of 50,000 MT to ensure timely fulfillment.
