Overview

Security tape and seals are often used to detect tampering while a shipping carton is in transit or storage. However, pilferage can occur after the carton sealing tape is slit on a carton seam, then re-sealed with clear packing tape. To the un-trained eye, this technique can be difficult to detect prior to signing the bill of lading to accept the goods. Our pilfer-guard seals provide a more visible means to detect this type of pilferage.

The pilfer-guard seals have a special chemical coating, which is activated by direct contact with adhesive in carton sealing tape. If clear tape is placed over the “pilfer-guard” to re-seal the carton, the hidden word “OPEN” appears 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.

Apply carton sealing tape, then affix the Pilfer Guard Seal on the carton seams -- both top and bottom.

The word OPEN appears if clear tape is applied over the Pilfer Guard Seal to reseal the carton.

The seals also have a tamper evident construction; if the “pilfer-guard” is removed, it will leave the message “OPENED” in the seal and on the carton.
