Heat-Resistant Matte Finish Electrolytic Tin Plate Coils for Food Can Manufacturing

This product is a specialized Electrolytic Tin Plate (ETP) characterized by its distinctive matte surface finish and engineered for superior heat resistance. Manufactured using a precise electrolytic deposition process on a cold-rolled steel base, this tinplate is a critical raw material for producing durable metal packaging. Its primary application is in the manufacture of food cans, including those for retort or heat-sterilized products (like fish, tomato, and peach cans), aerosol containers, and paint cans. The matte finish provides an excellent substrate for high-quality printing and lacquering, while the BA (Bright Annealed) and CA (Continuous Annealed) tempers ensure optimal formability for demanding fabrication processes like drawing and stamping into DR8-grade can bodies and ends.

• Matte Surface Finish: Offers a uniform, non-glare surface that ensures superior ink adhesion and high-definition print quality for branding.

• Enhanced Heat Resistance: Specially processed to withstand high-temperature sterilization and retort processes without compromising coating integrity or causing delamination.

• Excellent Formability: The BA/CA annealing process provides a uniform microstructure, allowing for deep drawing and severe forming operations essential for creating complex can shapes (e.g., DR8 specifications).

• Robust Corrosion Defense: The combined properties of the tin coating and substrate steel provide reliable resistance against rust, acids, alkalis, and sulfide staining from aggressive food contents.

• Material Consistency: Available in a comprehensive range of hardness grades (TS230-TH620) to match specific strength and flexibility requirements for different parts of a container.

Utilizing this heat-resistant matte tinplate translates to enhanced manufacturing reliability and end-product performance. It ensures package integrity through thermal processing, extending shelf life and ensuring food safety. The matte surface reduces light reflection, potentially offering better product protection, and guarantees vibrant, durable printed graphics. Its consistent quality leads to higher production yields on high-speed can-making lines, reducing waste and operational downtime.

Q1: What is the main benefit of a matte finish compared to a bright finish?A1: A matte finish provides a rougher, non-reflective surface that significantly improves paint and ink adhesion. This results in more durable, scratch-resistant printing, which is ideal for high-quality branding and labeling on cans.

Q2: Why is heat resistance important for tinplate used in food cans?A2: Many food products undergo retort sterilization, a high-temperature, high-pressure process. Heat-resistant tinplate prevents coating breakdown, discoloration, or loss of adhesion during this process, ensuring the can's protective barrier remains intact.

Q3: What does "DR8" refer to in tinplate applications?A3: DR8 is a standard temper designation indicating a deep drawing quality. Tinplate supplied as DR8 is specifically engineered for severe forming operations, such as drawing the cylindrical bodies of two-piece cans, without tearing or fracturing.

Q4: Can you provide custom-sized sheets or slit coils?A4: Yes. We offer extensive customization for width (600-1020mm) and length (600-1200mm for sheets). Coils can be slit to your precise width requirements to optimize material yield and reduce scrap in your production line.

Q5: What certifications support your quality claims?A5: Our production is backed by Mill Test Certificates that verify chemical composition and mechanical properties. We adhere to international standards equivalent to AISI, ASTM, DIN, and JIS, ensuring global acceptability.
