Food Grade Printed Electrolytic Tinplate (SPTE/TFS) Sheets & Coils for Premium Can Packaging
Product Description
Electrolytic Tin Plate (ETP), commercially designated as SPTE, along with its counterpart Tin-Free Steel (TFS), forms the cornerstone of modern, visually appealing metal packaging. This product line features prime-grade, cold-rolled steel that undergoes a precise electrolytic process, coating it with either pure tin (SPTE) or chromium (TFS). Specifically engineered for high-quality food and beverage can production, it is further enhanced with professional-grade lithographic printing, transforming the base material into a ready-to-fabricate, branded packaging component. The combination of the metallic substrate's inherent strength and the vibrant, durable printed graphics makes it ideal for creating eye-catching food cans, beverage containers, artistic tins, as well as can ends and lids, ensuring product safety and standout shelf presence.
Features & Characteristics
-
High-Definition Lithographic Printing:
Enables complex, multi-color graphics and sharp text to be printed directly onto the metal surface, providing superior branding and aesthetic appeal compared to labeled cans.
-
Food-Grade Material Safety:
Manufactured from certified MR/SPCC steel with non-toxic coatings, ensuring full compliance with food contact regulations and guaranteeing product hygiene.
-
Dual-Material Flexibility:
Offers the choice between SPTE, known for its excellent solderability and overall corrosion resistance, and TFS, prized for its superior paint adhesion and resistance to sulfide staining.
-
Multi-Faceted Corrosion Protection:
Provides inherent resistance to rust, and when combined with appropriate internal lacquers, offers robust defense against acidic and alkaline food contents.
-
Excellent Fabrication Properties:
Available in a range of tempers (T1-T5, DR7-DR9) and hardness levels to ensure optimal performance in stamping, deep-drawing, welding, and seaming operations.
Key Advantages
Choosing our pre-printed Electrolytic Tinplate streamlines your manufacturing process and elevates your brand. It consolidates material sourcing and decoration into a single, reliable supply chain, reducing production steps and inventory complexity. The direct printing ensures a durable, high-quality finish that resists scuffing and moisture. The material's proven performance ensures package integrity, while its 100% recyclability supports sustainability goals. Full traceability is provided through Mill Certification and compliance with international standards (JIS, DIN, ASTM).

Frequently Asked Questions (FAQ)
Q1: Can you print custom designs, including complex logos and gradients?
A1: Yes, our advanced lithographic printing process supports high-resolution, multi-color designs using standard CMYK or specific Pantone (PMS) colors. You can supply your artwork, and we will produce printed sheets/coils with precise color matching and detail.
Q2: What is the main advantage of using pre-printed tinplate versus printing after can formation?
A2: Printing on flat sheets/coils allows for higher print quality, registration accuracy, and speed. It eliminates the challenges of printing on a curved, formed surface and often results in a more durable finish with fewer defects.
Q3: How do I decide between printed SPTE and printed TFS for my project?
A3: If your can manufacturing involves soldering (e.g., three-piece cans), SPTE is necessary. If you use welding or your priority is maximizing the adhesion and longevity of internal protective lacquers (especially for aggressive foods), TFS is an excellent, often more economical choice. Both can be printed with equal quality.
Q4: Is the printed surface safe for direct food contact?
A4: The printing is applied to the external surface of the can. The internal surface remains coated with food-grade tin or chromium and can be further treated with FDA-approved protective lacquers, ensuring no contact between the ink and the food product.
Q5: What information do you need to provide a quotation for printed tinplate?
A5: Please specify: material type (SPTE/TFS), thickness, temper, dimensions, tin coating weight, the quantity of printed material, and provide your final print-ready artwork file for assessment.
