Intended Use

The PilferGuard™ adhesive seal is designed as a supplemental security seal for the seams of a corrugated carton. It can also be used as a conventional tamper evident label. When manually removed, part of the ink and adhesive separates from the film and sticks to the carton. The pattern of words "OPENED" will appear in the adhesive residue and in the label film.

The PilferGuard™ seals have a special chemical coating that is activated by direct contact with adhesive in carton sealing tape. If clear tape is placed over the PilferGuard™ to reseal the carton, the hidden word “OPEN” begins to appear (in yellow letters) about 2 hours later. The 2 hour delay is typically enough time to activate the hidden security feature before the package is delivered or accepted. When the carton is presented with the word “OPEN” prominently showing, the recipient can inspect the contents immediately to confirm if a theft claim is needed, prior to accepting the shipment.

This is a single use item.
