Evolution of Bottle Closures
The mid-19th century Industrial Revolution spurred innovation in closure technology. In 1856, the first aluminum screw cap was invented, marking the beginning of the metal packaging era. Initially used for pharmaceutical sealing, it was gradually optimized for wider application. By the mid-20th century, aluminum screw caps became common in the liquor industry.
Precision-Engineered by HAOMEI Aluminum
HAOMEI Aluminum's 30x35mm aluminum ROPP cap is specially engineered for liquor bottles. The 30mm diameter and 35mm height are designed to precisely fit most standard spirit bottles, ensuring secure sealing and excellent compatibility.
Manufactured from high-strength, food-grade aluminum alloys such as 8011-H14 or 3105-H16, these caps offer superb ductility and corrosion resistance. They are perfectly suited for high-speed filling lines involving deep drawing and rolling seal processes.
Each cap can be equipped with leak-proof liners-including PE, EPE, or T-type liners-that, combined with precision knurling and thread-rolling technology, ensure a tight seal. This minimizes evaporation and leakage, effectively extending product shelf life.
