About this item The Latest And Highest Security Tape : In addition to the hidden “VOIDOPEN” message, the Tri-colour tape will separate into 2 distinct colours if triggered. This feature is what makes the tape so secure and highest security, you can see at a glance if package has been opened! Pre-Assigned Serial Numbers for Added Security : Unique Serial Numbers are ideal for added security to record it on the bill of lading and provide traceability for your assets, making the replacement of the same tape impossible. Easy to Tear by Hand, No Scissors Needed : Every 6 inches (the length of A3/A4 envelope opening) in tape repeated a perforation, which will surely help you tear off the tape by hand very easily, and avoid any complaint “tape may stick to scissors when cut”. No Waiting Period to Reveal “Void” : Security hidden messages will be 100% totally transfered to the application surface immediately in a FEW SECONDS if attempts are made at removal of tape, while other security tapes usually needed at least a few minutes to reveal “void”. Unique Plastic Core & Protective Film Laminated on Each Tape : Unlike others’ paper core, we use a 3” plastic core and laminate film on each security tape for you to get a clean and beautiful appearance.
