0.18mm CA-T5 Tinplate Sheet for Food Cans - 2.8/2.8g/m² Coating

Modern high-speed container production lines require structural packaging substrates that provide exceptional vertical crush resistance and precise shape control. Our 0.18mm thickness Tinplate sheet series represents a highly specialized model, engineered through continuous annealing (CA) to achieve a resilient T5 hardness classification. By passing the cold-reduced steel strip through a rapid, automated vertical furnace tower, the material gains a completely uniform crystalline matrix. This precise thermal processing makes this thin-gauge sheet an ideal choice for manufacturing lightweight, high-strength three-piece food can bodies, aerosol containers, and rigid easy-open end components.

Developed specifically to function as a cost-effective and dependable food can material, this 0.18mm sheet features an equal 2.8/2.8 g/m² tin coating mass deposited via a continuous electrolytic plating line. This standard coating weight delivers a dense, pinhole-free metallic barrier that prevents ambient moisture, oxygen, and mild food acids from contacting the raw steel core. The sheets are finished with an inorganic chromium passivation film and a micro-layer of food-grade oil, creating a flat surface layout with zero edge-wave. This allows automatic vacuum feeders and magnetic cup-forming lines to run smoothly without double-sheet errors or unexpected machine stops.

The specific physical and chemical properties of our 0.18mm CA-T5, 2.8/2.8g/m² tin-plated sheets ensure reliable performance under high mechanical stress:

• High-Strength 0.18mm Thinner Gauge: The 0.18mm nominal thickness enables material down-gauging, reducing overall container weight and shipping costs while maintaining high column collapse strength.
• Continuous Annealing (CA-T5) Stiffness: Provides high yield strength and a rigid mechanical profile, giving containers excellent vacuum resistance and preventing body panelling during thermal cooling cycles.
• Standard 2.8/2.8 g/m² Defensive Barrier: The uniformly deposited tin layer forms an effective chemical shield on both sides, preventing rust and surface corrosion across all standard food packaging categories.
• Excellent Surface Cleanliness and Tension: The passivated finish offers optimal energy levels, ensuring complete compatibility and a tight chemical bond with protective epoxy-phenolic, organosol, or vinyl base lacquers.

Choosing our standardized 0.18mm Tinplate sheet model provides clear mechanical and economic advantages to automated, high-volume canning plants. The primary advantage stems from the material's continuous annealing processing, which guarantees identical mechanical hardness and thickness profiles from edge to edge across every sheet. Because the metal behaves predictably under heavy stamping dies, can makers can maintain fixed press calibrations, reduce tool wear, and cut down on line changeover times.

Additionally, using a 2.8/2.8 g/m² tin mass combined with an internal lacquer coating creates an efficient protective system at an economical price point. When used as a food can material, the tin layer acts as a sacrificial anode. If microscopic scratches occur in the internal lining during high-speed rolling, body expansion, or mechanical seaming, the tin protects the steel core from corrosion. This sacrificial barrier stops rust spots and pinhole leaks from forming, helping to preserve the original freshness, natural aroma, and flavor profiles of vegetables, fish, meats, and milk powders throughout their shelf lives.
