A tamper-evident seal is a sealing device designed to reveal if the opening of a container has been interfered with. The package is closed with a tamper-evident seal, so you can see if it has been interfered with before you open it.
They provide visual evidence of any attempt to open or manipulate that package. Ultimately, it discourages unauthorized opening or tampering. Even a premier tamper evident seal is not a lock. Instead, the seal is typically designed to be used only once before being destroyed.
