Tamper-evident band

rdf:langString Tamper-evident band

rdf:langString A tamper-evident band or security ring serves as a tamper resistant or tamper evident function to a screw cap, lid, or closure. The term tamper-proof is sometimes used but is considered a misnomer given that pilfering is still technically possible. A security band can be integral with the cap or can be a separate package component. It is a plastic or metal structure around the circumference (usually) of the closure that is often found attached below a closure in bottles, jars, and tubs. Several variations have been developed for caps, lids, and closures. The use of custom printing and security printing is available. Perforations or other areas of weakness are often used to initiate and control a tear. Sometimes engineered frangibility is used for break-away functions. 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. The opening ring is a tamper warning: if the seal between the ring and the cap is broken, it is an indication that the cap has been opened.
