The numbered Arrow seal is a tamper-evident plastic seal designed for reusable security bags, pouches and envelopes fitted with an Arrow-type locking mechanism. It is used to create a clear, verifiable closure where it must be possible to check whether the contents have been accessed, opened or handled without authorisation during transport, storage or internal circulation.
Each seal is laser marked with two letters and a unique sequential number. This makes it easy to record which seal was used at the point of closure and to verify the same number at receipt, handover or inspection. The individual numbering adds an important level of traceability and is particularly useful in workflows where responsibility, chain of custody and documented control are important.
The seal is inserted into the locking chamber once the zip puller has been placed in the correct position. When the bag is opened, the seal must be broken, giving a clear visual indication that the closure is no longer intact. The product is suitable for reusable security bags and pouches used in internal mail, document handling, key management, healthcare, retail, service operations, warehousing and other environments where the integrity of the contents needs to be controlled.
