Food Grade Tinplate Coil - ASTM A623 Certified Steel for Food Packaging

Technical Specifications of Food Grade Tinplate Coil

Food Grade Tinplate Coil - ASTM A623 Certified Steel for Food Packaging

Food grade tinplate coil represents a specialized cold-rolled steel product electroplated with a thin layer of tin, specifically engineered for direct contact with consumable goods. This premium-grade material serves critical roles in the food and beverage packaging industry, where superior corrosion resistance, non-toxicity, and regulatory compliance are paramount. Manufactured to stringent international standards, food grade tinplate coil delivers the optimal combination of formability, weldability, and surface finish required by packaging manufacturers, canneries, and food processing facilities worldwide.

What is Food Grade Tinplate Coil?

Food grade tinplate coil is cold-reduced carbon steel sheet coated with commercially pure tin through an electrolytic deposition process, meeting FDA 21 CFR 175.300 and EU Regulation 10/2011 requirements for food contact materials. The base steel typically conforms to ASTM A623 specifications, featuring carbon content limited to 0.13% maximum and tin coating weights ranging from 2.8 to 11.2 g/m² per surface, providing exceptional barrier properties against moisture, oxygen, and light penetration.

Food Grade Tinplate Coil Technical Specifications

Our food grade tinplate coil complies with ASTM A623/A623M-17 Section 5.1 for chemical composition and ASTM A599-18 for tin coating weight verification. Standard thickness ranges from 0.15mm to 0.49mm with tolerances per EN 10202:2001 Table 3, while coating designations follow the T-1 through T-5 classification system. Temper grades include T-1 (extra hard) through T-6 (dead soft), with yield strength values from 210 MPa to 550 MPa depending on reduction ratio and annealing parameters.

Why Choose Our Food Grade Tinplate Coil

We supply mill-direct food grade tinplate coil manufactured under ISO 22000:2018 certified food safety management systems, ensuring full traceability from steel melting through final passivation treatment. Our production facilities maintain Class 100,000 cleanroom standards during coating application, eliminating particulate contamination risks. Each coil includes comprehensive mill test certificates documenting tin coating weight via X-ray fluorescence analysis per ASTM B568-98, along with migration test reports demonstrating compliance with FDA total extractables limits of 0.5 mg/in² maximum.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ for food grade tinplate coil is 25 metric tons per specification, equivalent to approximately one full container load. For established customers requiring mixed temper grades or coating weights, we accommodate split orders of 10 tons minimum per variant, subject to production scheduling availability and applicable setup charges.

Do you provide material test certificates?

Yes, we issue EN 10204 Type 3.1 mill test certificates for every food grade tinplate coil shipment, certified by our independent third-party inspection agency. Documentation includes chemical composition analysis per ASTM E415-17, mechanical property verification per ASTM E8/E8M-21, tin coating weight measurements, and food contact migration test results conducted according to FDA 21 CFR 175.300 protocols.

What is the typical delivery time?

Standard delivery time for food grade tinplate coil is 35-45 calendar days from purchase order confirmation, including 25 days for production scheduling and cold rolling operations, 7 days for electrolytic tinning and passivation treatment, and 3-5 days for quality inspection and documentation preparation. Expedited production is available for urgent requirements with 20-25 day lead times at premium pricing.

Can you cut to custom sizes?

We provide precision slitting services for food grade tinplate coil with width tolerances of ±0.5mm per EN 10202:2001 standards, accommodating strip widths from 60mm to 1,220mm. Shearing to custom lengths is available with tolerances of ±1.0mm, utilizing servo-controlled flying shear systems that prevent edge deformation and maintain coating integrity across cut surfaces.
