ROPP Capper stands for Roll On Pilfer Proof Capper.  The ROPP Capper places an aluminum shell cap onto your container.  The capping head then descends and uses custom knives to thread the cap onto the container! 

ROPP Cappers normally come with thread screw head consisting of four custom manufactured knives for threading the cap and container.  This type of head is ideal for products that require tamper proof capping.  The ROPP Capper and thread screw head provide proof that the container has been sealed and has remained sealed until it reaches the end user!

Capping heads for plastic caps are also avaialble for the ROPP Capper.
