Do Lug Caps Have Anti-Drop or Anti-Crack Designs?

 

Do Lug Caps Have Anti-Drop or Anti-Crack Designs?

Kamellia’s metal lug caps are primarily designed for sealing and preventing product deterioration, and are not specially reinforced with anti-drop or anti-crack features.

 

Why Don’t Lug Caps Have Anti-Drop or Anti-Crack Designs?

Different Functional Purpose
The main function of lug caps is to ensure an airtight vacuum seal at the bottle mouth, preventing food and beverages from being contaminated or oxidized during storage. Anti-drop or anti-crack protection, however, falls under the characteristics of the container itself (such as glass or plastic bottles), not the cap.

Material Limitations
Metal lug caps are usually made of tinplate or electrolytic chromium-coated steel. While these materials provide rigidity and sealing performance, they are not impact-resistant. In cases of dropping or strong impact, it is the bottle body that bears the stress, and the lug cap cannot serve a protective anti-crack role.

Practical Application Context
During transportation, anti-drop and anti-crack protection for food and beverages primarily relies on cartons, dividers, and cushioning materials, not on the cap structure. Overemphasizing impact resistance in lug caps may instead compromise vacuum sealing performance and ease of opening.
