5.6/5.6 Tin Layer EOE Lids: Specs, Benefits, and Sourcing Guide
5.6/5.6 tin layer EOE lids are easy-open ends for tinplate cans that have an equal tin coating of 5.6 g/m² on both the top and bottom surfaces. This symmetrical coating provides balanced corrosion resistance and consistent seaming performance, making these lids a common choice for food and beverage packaging.
What does 5.6/5.6 tin layer mean on EOE lids?
The numbers refer to the tin coating weight per unit area. 5.6/5.6 means 5.6 grams per square meter on each side of the steel substrate. Unlike differential coatings (e.g., 2.8/5.6), this equal layer ensures uniform protection against acidic contents and reduces the risk of localized corrosion.
Why choose 5.6/5.6 tin layer EOE lids?
Balanced tin layers offer several advantages. First, they provide consistent weldability and lacquer adhesion on both sides. Second, they simplify inventory because the lid can be oriented either way without affecting performance. Third, they extend shelf life for products like tomato paste, fruit, and pet food.
Are 5.6/5.6 tin layer EOE lids suitable for all can sizes?
Yes, these lids are available in standard diameters such as 202, 300, 307, and 401. The coating weight remains 5.6/5.6 regardless of size, but the steel thickness may vary to match the can body.
How do you order 5.6/5.6 tin layer EOE lids from China?
To order tinplate to Guangda factory in China, you can contact their sales team with your specifications: diameter, coating weight, lacquer type, and quantity. Guangda is a well-known supplier of tinplate and EOE lids, and they can produce custom orders. Always request a sample before mass production.
What should you check before buying?

Conclusion
5.6/5.6 tin layer EOE lids offer a reliable, symmetrical coating that suits many canned goods. When sourcing, consider both quality and logistics, and don't hesitate to order tinplate to Guangda factory in China for competitive pricing.
