Are Kamellia’s Lug Caps Suitable for Carbonated Beverages or Products Containing Gas?
Kamellia’s metal lug caps are primarily designed for the vacuum sealing requirements of juices, sauces, pickled foods, health products, and general beverages. They are not suitable for carbonated beverages or gas-containing products.
Why Are Lug Caps Not Suitable for Carbonated Beverages?
Different Sealing Principle
Lug caps rely on metal lugs gripping the bottle finish, combined with a liner and vacuum sealing. This design is suitable for atmospheric or vacuum-sterilized products (such as jam, sauces, or juice) but is not intended to withstand long-term internal pressure.
Insufficient Pressure Resistance
The internal pressure of carbonated beverages can reach 2–4 bar (or higher, depending on temperature and formula). Lug caps are not designed to resist this level of gas expansion, which may cause:
- Cap deformation
- Seal failure
- Gradual leakage of carbon dioxide
Safety Risks
If internal pressure is too high, lug caps may suddenly pop off during handling or opening, posing a risk of injury to consumers.
Impact on Product Quality
Carbonated beverages lose carbonation if the seal cannot hold, resulting in a flat taste and poor consumer experience.
Recommended Cap Types for Carbonated Beverages
- Plastic Screw Caps (PET bottles): Reinforced for pressure resistance, with safety rings, commonly used for soda and soft drinks.
- Crown Caps: Used for glass-bottled beer and soda, capable of long-term high-pressure resistance.
