Security Bags, Envelopes & Pouches

Security bags, envelopes and pouches are tamper-evident solutions designed to protect items in transit or storage. Tamper proof bags and envelopes reduce the risk of transporting many types of sensitive items, providing an additional layer of security and a deterrence to potential theft or fraud. Choose from polythene single-use envelopes for secure mailing, healthcare samples and cash deposits, or durable reusable secure pouches ideal for internal mail and cash-in-transit operations. Each bag is designed to provide clear tamper evidence, with features such as VOID closures, sequential numbering and barcode tracking, ensuring traceability and compliance. Standard sizes include A5, A4 and A3, with flat or gusseted options, while custom printing is available (for example, see our customised security bags). 

Security bags are commonly used as secure mail bags (e.g. for sealing confidential documents like exam papers); as cash deposit bags (AKA "cash-in-transit" /"CIT" bags); and as security bags for clinical items and police evidence. Our secure tamperproof bags and envelopes reduce the risk of transporting many types of valuable or sensitive items, providing an additional layer of security and a deterrence to potential theft or fraud. Our solutions deliver trusted security for organisations across logistics, healthcare, retail, banking, government and law enforcement.
