Cost-Effective, Sulfur-Resistant, and Printable Packaging Material

Tin-free steel (TFS / ECCS) is a widely used packaging steel known for its excellent lacquer adhesion, corrosion resistance, and stable formability. CJM supplies TFS coil and TFS sheet with consistent coating quality for food cans, crown caps, chemical containers, and general industrial packaging applications. Our mill-supported sourcing ensures reliable supply, export-ready dimensions, and fast delivery to global buyers.

What Is Tin-Free Steel (TFS / ECCS)?

Tin-free steel, also known as electrolytic chromium-coated steel, is produced by applying a thin layer of metallic chromium and chromium oxide onto low-carbon steel. It serves as an alternative to tinplate, offering excellent adhesion for organic coatings and strong corrosion protection in packaging applications.

As an exporter, CJM works directly with certified TFS coil factories to ensure stable quality and international-standard specifications.

These tin free steel specifications can be customized for different can-making lines and packaging designs.

Mechanical Properties of TFS for Packaging

Grade	Yield Strength (MPa)	Tensile Strength (MPa)	Elongation (%)
T2	≥ 245	270–350	≥ 30
T3	≥ 275	300–370	≥ 28
T4	≥ 305	340–410	≥ 26
DR8	≥ 370	420–510	≥ 2.5
DR9	≥ 410	470–560	≥ 1.5

Technical Note:
DR8 and DR9 are Double Reduced tempers for ultra-high hardness. Formability is measured by ear test, hardness, and punchability — essential for crown caps, can ends, and high-speed forming lines.

Key Benefits of TFS Coil & Sheet for Packaging

• Cost-Effective Alternative – Lower tin free steel price compared with electrolytic tinplate while meeting the same packaging standards.
• Superior Lacquer Adhesion – The chromium oxide layer is micro-porous, creating strong anchor points for coatings and inks. This ensures excellent paint and lacquer bonding — ideal for printable tin free steel packaging.
• High Corrosion Resistance – Especially suitable for sulfur-containing foods and beverages that require long shelf-life protection.
• Food-Safe with Lacquering – For direct food contact, tin free steel food packaging applications must be lacquered internally to ensure safety and prevent contamination.
• Formability & Strength – Suitable for can ends, crown caps, closures, and aerosol domes that require both durability and shaping performance.
• Decorative Potential – The smooth surface finish (bright, matte, or silver) supports branding and decorative printing on tin free steel cans.

Applications of Tin-Free Steel Packaging

Our TFS packaging steel is widely used in various applications:

• Food and beverage can ends
• Cosmetic and medical packaging
• Paint and coating cans
• Crown caps and bottle closures
• Aerosol domes and bottoms
• Battery jackets and industrial containers

Because of its excellent sulfur corrosion resistance, tin free steel packaging is ideal for acidic foods, sulfur-containing beverages, and products requiring long shelf-life and decorative printing.

FAQ: Tin-Free Steel vs Tinplate

Compared with tinplate, tin free steel coils are more cost-effective while still providing excellent lacquer adhesion and corrosion resistance. For a detailed comparison, see our full guide: Tinplate vs. Tin-Free Steel for Packaging Needs.

Q1: Is tin-free steel safe for food packaging?

Yes — but only with internal lacquer. Tin free steel sheets and coils must be lacquered before direct food contact to ensure safety.

Q2: What is the difference between electrolytic tinplate and tin-free steel?

• Electrolytic Tinplate: Tin coating, safe for direct food contact, glossy finish.
• Electrolytic Chromium-Coated Steel (TFS / ECCS): Chromium coating, requires lacquer, superior adhesion, and lower cost.

Q3: Can tin-free steel replace tinplate in all applications?

Not always. Tinplate is preferred for uncoated direct food contact.
TFS tin free steel is better for chemical packaging, lacquered food lids, and sulfur-rich canned products.
