Electrolytic Tin Plate (ETP) represents the gold standard in food packaging materials, specifically engineered to withstand the challenging environments of acidic and alkaline food products. This advanced material features a cold-rolled low-carbon steel base with a precision electrolytic tin coating that creates an exceptional protective barrier. The tin layer effectively isolates the steel substrate from food contents, preventing chemical reactions that could compromise food quality and safety. The material's unique acid resistance makes it ideal for tomato-based products, citrus fruits, and pickled foods, while its alkaline resistance ensures reliable performance with products containing alkaline additives or buffers. Available in various tempers and surface finishes, this versatile material supports efficient manufacturing processes while ensuring product integrity throughout the shelf life.

• Superior acid resistance protects against corrosive food contents like tomatoes and citrus fruits
• Excellent alkaline resistance handles products with alkaline additives and buffers
• Food-grade certification ensures compliance with international food safety standards
• Precision thickness control with ±0.01mm tolerance for manufacturing consistency
• Excellent formability and weldability for efficient can production
• Multiple surface finishes accommodate different aesthetic requirements
• Environmentally sustainable with full recyclability
• Cost-effective solution with reliable performance and extended shelf life

• Tomato-based products and sauces
• Seafood and fish packaging
• Meat products and ready-to-eat meals
• Fruit preserves and citrus products
• Aerosol containers and specialty packaging

1. How does the acid resistance protect food products?
   The tin layer forms a protective oxide film that prevents acidic contents from corroding the steel substrate, ensuring food quality and safety throughout the shelf life.
2. What types of alkaline foods can this material handle?
   It's suitable for products with alkaline additives, functional beverages with buffers, and foods that become alkaline through special processing methods.
3. Can you provide customized coating weights?
   Yes, we offer customizable tin coating from 1.1/1.1 to 5.6/5.6 g/m² based on specific application requirements and food types.
4. What certifications do you maintain?
   Our products are certified with SGS and mill certificates, ensuring compliance with international food safety and quality standards.
5. What is the minimum order quantity?
   Our standard MOQ is 25 tons, with flexibility for established business relationships and larger projects.
