Introduction to Cable Seals

Cable seals are essential security devices used in various industries to prevent unauthorized access, tampering, and ensure the integrity of goods during transportation and storage. They are typically made of high - strength materials such as plastic, metal, or a combination of both. Cable seals consist of a cable and a locking mechanism. The cable can be threaded through items or containers, and once locked, it cannot be removed without breaking the seal, leaving visible evidence of any tampering. These seals are widely used in logistics, shipping, customs, and many other sectors where security and traceability are crucial.
