What is security seals?

Security seals are mechanisms used to seal containers in a way that
provides tamper evidence and some level of security(HIGH
SECURITY,SECURITY,INDICATIVE). Such seals can help to detect theft or
contamination, either accidental or deliberate. Security seals are
commonly used to secure vehicles, chemical drums, airline duty free
trolleys and utility meters etc. Typically they are considered an
inexpensive way of providing tamper evidence of intrusion into
sensitive spaces.
