2.8/2.8 Prime Electrolytic Tinplate Sheet MR Type T3 Temper for 200D Food Can Lid Stamping 0.18mm-0.25mm Thickness

2.8/2.8 Electrolytic Tinplate Sheet T3 Temper for 200D Food Can Lid Production

This premium 2.8/2.8 electrolytic tinplate sheet in T3 temper is purpose-engineered for high-speed 200D food can lid stamping operations. Sourced from certified mills with advanced electrolytic tinning lines, each sheet delivers uniform tin distribution and consistent mechanical properties across the entire coil length, ensuring reliable forming behavior in automated press lines.

Key Performance Features

• Dual-Sided Uniform Coating: 2.8/2.8 g/m² tin coating mass provides balanced corrosion protection on both surfaces, critical for food contact applications requiring inert packaging materials.
• T3 Temper Precision: HR30T 55-61 hardness range offers the ideal balance between formability and stiffness, enabling clean lid stamping without cracking, wrinkling, or excessive springback during double-seaming operations.
• Superior Surface Quality: Available in stone finish or bright finish to accommodate different lid appearance requirements, with strict control over surface roughness (Ra 0.25-0.45 μm) for optimal lacquer adhesion.
• Wide Dimensional Range: Thickness from 0.18mm to 0.25mm and width from 600mm to 1050mm, compatible with most commercial lid stamping tooling and coil feed systems.
• Strict Flatness Tolerance: Maximum flatness deviation of ≤3mm per 1000mm ensures stable feeding and consistent blank positioning in high-speed presses.

Technical Specifications

Quality Assurance

Every shipment undergoes rigorous inspection including: cross-cut adhesion testing per ISO 2409, Olsen cupping test for drawability, visual inspection under 1000 lux illumination, and dimensional verification with calibrated digital micrometers. Mill test certificates (MTC 3.1 per EN 10204) provided with each delivery.

Packaging & Shipping

Sheets are packed on export-grade fumigated wooden pallets with VCI anti-rust paper interleaving, sealed in heavy-gauge polyethylene film, protected with hardboard edge guards, and secured with hardened steel strapping bands rated for ocean container transport.
