Security Envelopes, Bags & Pouches

Our security envelopes, pouches and bags are available in both single-use and re-useable variations. Single use security bags are manufactured in polythene, with platinum tamper-evident adhesive seal, printed with sequential numbering and with a tear-off receipt for control - a full guide to our customised security bags is available here. Our re-usable secure mail bags and pouches are manufactured in durable PVC and incorporate a number of tamper-evident features to ensure the secure transportation of high-value or confidential contents. The use of tamper-evident seals to lock the zip ensures the integrity of the contents as well as well acting as a deterrent to unauthorised access.

Security bags have a wide range of uses, including as secure mailing bags (for the sending of sensitive or confidential documents, such as examination papers); cash deposit and transport bags (AKA cash-in-transit bags), evidence bags for police and forensic use, and many other applications. Secure, tamperproof bags and envelopes reduce the risk of transporting many types of valuables; for example, providing an additional layer of security as a courier security bag. They can also be used for controlled storage of personal possessions, for example, for event security or prisoner property.
