Can Metal Lug Caps Be Used for Dairy and Fermented Products?

Special Requirements of Dairy and Fermented Products

Dairy and fermented products (such as yogurt, lactic acid beverages, kefir, etc.) have different packaging needs compared to general foods. These products often contain live probiotics, require low-temperature storage, and in some cases, the fermentation process continues inside the bottle, generating gas.

If the cap’s sealing performance is insufficient, this can easily lead to oxidation, microbial contamination, or pressure build-up, ultimately affecting flavor and shelf life. This is why the suitability of metal lug caps has become an important concern for the industry.

Reliable Performance in Sealing and Preservation

The answer is yes: Kamellia’s metal lug caps are fully suitable for dairy and fermented products.

• Dairy Applications

Paired with PE or silicone liners, the caps effectively block external air and impurities, preserving the freshness of milk, yogurt, and lactic acid beverages, while extending refrigerated shelf life.

• Fermented Product Applications

For beverages that generate gas inside the bottle, lug caps are designed with structural flexibility and liner resilience to withstand pressure changes. They maintain stable sealing, preventing leakage or cap dislodgement.

Common Applications:

• Dairy: yogurt, flavored milk, fermented milk drinks
• Fermented beverages: lactic acid drinks, kefir, probiotic beverages
• Nutritional supplements: probiotic liquid supplements, functional beverages

From the above, it is clear that metal lug caps combine sealing ability, pressure resistance, and food safety—fully meeting the needs of dairy and fermented products.
