A plastic security seal is a tamper-evident device used to secure various containers and goods. It is designed to provide a visual indication of tampering, ensuring that the contents remain intact and untouched during transit. These seals come in various forms, such as the fixed-length seals shown on this page, as well as pull-tight seals, meter seals, tote box seals, and so on. Each type serves a different security need across particular applications and industries.
