Product type
ROPP caps, or Roll-On Pilfer Proof caps, are a type of closure commonly used in the packaging industry to seal bottles and containers. These caps are typically made from aluminum or plastic and are designed to provide tamper evidence and ensure product integrity. The unique design allows the cap to be rolled onto the bottle neck, creating a secure seal that is difficult to open without leaving visible evidence of tampering.
