Tamper Evidence Seals
A tamper-evident seal is a seal or closure that indicates whether it has been interfered with or removed. It is usually being used for packaging to reveal if the content of the packaging is being tampered.
Watermark is a subtle image permanently impressed into paper during the manufacturing process. It identifies the source of the sheet and may contain, for instance, the paper mill’s trademark or the brand name of the paper. Watermarks indicate high-quality paper and are symbols of authenticity and distinction in business and personal correspondence. Watermark paper was made by impressing a water-coated metal stamp or dandy roll onto the paper during manufacturing.
A security thread is a security feature of many banknotes to protect against counterfeiting, consisting of a thin ribbon that is threaded through the note's paper. Usually, the ribbon runs vertically and is "woven" into the paper, so that it at some places emerges on the front side and at the remaining places at the rear side of the paper. Usually, it is made of metal foil, but sometimes of plastic. Often, it has some text or numbers (e.g., the denomination) engraved.
Destructible paper or anti-dismantle label breaks apart into small pieces when removal is attempted, thus providing complete protection to goods against pilferage or tampering.
