tamper-evident band
security ring , also: tamper-evident closure

Tamper resistant or Tamper-evident bands or seals.

In a 1997 study on the potential hazards from carbonated drink bottles for the public, 7 people out of 180 admitted that they remove the tamper-evident band from bottles with scissors or knives.

Anglo Polymers is the European distributor for a range of high quality, clear, heat-shrinkable film which can be colour printed for packaging applications such as full body labels, tamper-evident bands and cap seals.

While tamper-evident bands are not considered a challenge for recycling, it is important that the band stays attached to the cap in case of refillable bottles, because it is hard to remove the rings from intact bottles in an economical way.
