Industry Standard Compatibility
Olive oil bottles commonly use a 28-410 neck finish (28mm outer diameter with 410 continuous thread type), which is ideal for glass bottles ranging from 8 to 32 oz. This specification ensures that the aluminum cap tightly fits and seals seamlessly with the bottle opening.
Tamper-Evident Function
The twist-off aluminum anti-theft bottle cap manufactured by HAOMEI Aluminum are often integrated with a tamper-evident band. Upon first opening, the band detaches, preventing the risk of refilling or product tampering. Our olive oil caps are available in sizes like 31.5x24mm, and can be customized with:
Embossed logos
Laser coding
QR codes
Hot foil stamping
These customizations enhance both product appeal and brand recognition.
Why Are Twist-Off Aluminum Caps Ideal for Olive Oil Bottles?
One-piece design, tamper-proof: The rolled thread structure remains intact before first use, providing visible evidence of any tampering.
Excellent sealing & oxidation prevention: Effectively prevents air from entering, maintaining the freshness and quality of olive oil.
Lightweight & corrosion-resistant: Aluminum is moisture-proof and rust-resistant, suitable for various shipping and storage conditions.
Premium look & customizable: Can be anodized, electroplated, or printed with brand logos to elevate product appearance and market value.
