30×60 mm Aluminum ROPP Caps Manufacturing Process

The caps are made by stamping aluminum sheets, installing the liner, and then molding the caps onto the bottle threads using a high-speed capping machine, activating the tamper-proof band.

Process Step	Description
Aluminum Sheet Stamping	The 30×60 mm Aluminum ROPP Caps are first made from high-quality aluminum sheets through a stamping process. The aluminum sheets are cut into predetermined sizes in the stamping machine, ensuring precise shape and size consistency for each cap, setting the foundation for the subsequent production steps.
Liner Installation	The manufactured aluminum caps are then fitted with liners. Liner materials such as PE (polyethylene), foil, or Sharon inserts are precisely placed inside the caps. The installation of the liner ensures a tight seal between the cap and the bottle neck, helping prevent leaks and maintaining the freshness of the contents.
High-Speed Capping Machine Molding	The 30×60 mm Aluminum ROPP Caps are molded onto the bottles in a capping machine, ensuring the caps are securely fastened to the bottle threads. The efficient capping machine ensures the caps are tightly sealed onto the bottle neck, activating the tamper-proof band for effective tamper-evident sealing.
Tamper-Proof Band Activation	During the sealing process, the tamper-proof band portion is activated, creating a clear tamper-evident design. Once the band is broken, the connection between the cap and the bottle will visibly rupture, allowing consumers to immediately notice if the product has been opened without authorization, ensuring product integrity and security.

These process steps ensure the efficient production and high-quality sealing of the 30×60 mm Aluminum ROPP Caps, meeting the stringent requirements for tamper-evidence and sealing for high-end products.
