High-Quality Materials and Finishes
The cap is made of durable aluminum with options for brushed or polished finishes. This enhances the product’s visual appeal while ensuring longevity and corrosion resistance.
Precise Dimensions and Threading
The cap is specifically designed for 28mm neck bottles using a 410 thread (commonly referred to as 28 ROPP), ensuring a tight and secure fit, which is crucial for maintaining product integrity during storage and transportation.
Effective Sealing with EPE Liner
The integrated EPE liner is a soft white foam insert that fits neatly inside the cap. When the cap is screwed onto the bottle, the bottle’s rim compresses the liner, creating a firm seal to prevent leaks and protect the contents from contamination.
Leak-Proof and Secure Closure
The cap’s design ensures a safe, leak-proof closure. This reliability is essential for maintaining the freshness of sensitive products, making it especially suitable for medical, cosmetic, and food applications.
Compatibility and Versatility
This aluminum cap is optimized for use with HDPE plastic bottles featuring a 28mm neck and can seamlessly integrate into various packaging production lines. It is often available alongside other 28mm closure options (such as plastic screw caps, lotion pumps, and sprayers) to meet diverse product requirements.
