Once the cap has been fully screwed on, when the bottle is opened for the first time, a small circular Polyethylene (PP) ring will detach from the bottom of the cap and attach itself to the neck of the bottle.
 
What is the PP28 ring?
ROPP - Roll On Pilfer Proof - rings, often abbreviated to PP for Pilfer Proof, are designed to accept a tamper-evident screw cap, i.e. a tamper-evident ring that breaks on first opening.
