Does Kamellia Provide Anti-Corrosion Lug Caps Suitable for Acidic Products?
Kamellia’s metal lug caps are suitable for acidic products with pH ≥ 4.0. For products with pH < 4.0 (such as lemon juice or vinegar drinks), it is recommended to use a customized acid-resistant formula and complete compatibility testing before mass production.
Why Does pH Value Affect Lug Caps?
Acidic substances accelerate metal corrosion. Even if the lug cap has a coating or liner, higher acidity, higher temperature, or longer storage time can all affect the corrosion resistance and sealing performance of the cap. Therefore, pH value is an important criterion in determining whether a lug cap is suitable.
Application Scope and Recommendations

| pH ≥ 4.0 | Can directly use Kamellia’s acid-resistant lug caps | Ketchup, some fruit juice drinks, vegetable pickling brine |
