28mm ROPP Caps Aluminum Caps

ROPP aluminum screw caps are widely used across various industries, including beverages (both alcoholic and non-alcoholic), pharmaceuticals, and food products. Their secure sealing and pilfer-proof design make them particularly suited for products that require secure, long-term storage.

The ROPP design involves a cap with threads that are formed directly into the aluminum during the capping process. This method requires a capping machine that rolls the threads into the cap and simultaneously seals it onto the bottle. The cap's design includes a pilfer-proof mechanism, typically a band or ring that breaks when the cap is first opened, providing a clear indication if the product has been tampered with.
