What is security seal？

A security seal is a tamper-evident device used to secure containers, cargo, equipment, or sensitive assets and to provide visible evidence of unauthorized access. Once applied, a security seal cannot be removed without breaking or damaging it, making any interference immediately noticeable.

Security seals are widely used in logistics, shipping, customs, utilities, aviation, and industrial applications. They help deter theft, prevent contamination, support compliance, and maintain the integrity of the supply chain.

Common types of security seals include plastic seals, Cable Seals, bolt seals, and Lead Seals, each designed for different security levels and use cases.
