25mm Aluminium Ropp Caps

The Roll-On Pilfer-Proof (ROPP) cap is a one-piece aluminum closure applied to glass or plastic bottles using a capping machine. The thread is formed during the capping process, creating a tamper-evident seal that breaks upon first opening. This design ensures product integrity and prevents counterfeiting.
