A ROPP (Roll-On Pilfer Proof) Capping Machine is designed to seal bottles with aluminum caps, ensuring a tamper-evident, pilfer-proof closure. This machine is commonly used in industries such as pharmaceuticals, beverages, food, and cosmetics where the safety and integrity of the product are crucial. The machine works by placing an aluminum cap over the bottle neck and using rollers to form threads and seal the cap securely. This process not only seals the container but also creates tamper-evident protection, as the cap cannot be opened without visible damage.
