Security seal

Security seals are tamper-evident mechanisms that seal valuable material in a room, cabinet, vehicle, or other storage facility. One common use is to seal cargo in transit shipping containers in a way that provides tamper evidence and some level of rudimentary security. Such seals can help to detect theft or contamination, either accidental or deliberate. Security seals are commonly used to secure truck trailers, vessel containers, chemical drums, airline duty-free trolleys, keys and utility meters. Typically they are considered an inexpensive way of providing tamper evidence of intrusion into sensitive spaces.
