Arrow seals, envopolyseals

Insert seals, also known as arrow seals or envopolyseals, are used to seal security packaging, cash cassettes, bags and other solutions designed for sealing with a separate insert seal. The seal is inserted into the intended locking chamber and locks the closure so that it is clearly visible if someone has opened or attempted to interfere with it.

This type of security seal is particularly common for reusable security packaging, cash cassettes and sealable bags where the packaging itself is used repeatedly while the seal is replaced each time it is closed. This provides a practical combination of reusability, simple control and clear tamper indication.

The range includes insert seals in several colours and versions, both numbered and unnumbered. Numbered seals and models with barcodes simplify documentation, traceability and control during handover, transport, receipt and internal handling. Colour coding can be used to distinguish between different flows, departments or areas of use.

Insert seals are suitable for organizations that require clear routines for secure closure, traceable handling and quick visual checks of whether a package or cassette has remained intact.
