acid-resistant tinplate sheet for cans
,ETP tinplate coils for tomato paste
,electrolytic tinplate sheet with corrosion resistance
High-performance ETP tinplate for tomato paste cans. Designed for acidic food with superior corrosion resistance, coating adhesion, and long shelf life stability.
Tomato paste is a highly acidic food product, which places strict requirements on packaging materials in terms of corrosion resistance and internal coating compatibility. ETP Tinplate (Electrolytic Tinplate) is widely used for tomato paste cans due to its strong barrier performance, structural stability, and excellent adhesion to protective coatings.
We specialized tinplate sheet and coil for tomato paste cans, engineered to perform under acidic conditions while maintaining product quality and safety throughout storage and transportation.
Typical specifications for tomato paste cans:
Thickness: 0.20–0.35 mm
Tin coating: 5.6/5.6 g/m² or higher
These parameters are recommended to enhance corrosion resistance and extend shelf life in acidic environments.

Engineering Note:
For high-acid applications, higher coating weight and proper lacquer system are critical to ensure corrosion resistance and product safety.
Tomato paste contains organic acids (such as citric acid), which can accelerate metal corrosion. Tinplate with higher coating weight provides enhanced protection, especially when combined with internal lacquer.
ETP tinplate ensures strong adhesion with specialized coatings such as:
- Epoxy phenolic lacquer
- BPA-NI coatings for acidic food
These coatings prevent direct contact between the food and metal, ensuring safety and durability.
- Suitable for deep drawing and can shaping
- Reliable double seaming for airtight sealing
- Consistent performance in high-speed production
- Prevents contamination and metallic taste
- Maintains product color and quality
- Supports long-term storage and export conditions
- Tomato paste cans
- Tomato sauce containers
- Fruit-based acidic products
- Ready-to-eat meals
- Processed vegetable products
- Can bodies
- Ends and lids
- Easy-open lids
