C3 / A3 Tamper Evident Security Bags are large-format, eco-friendly tamper evident bags for secure transport of A3 documents, parcels, medical files, and high-value consignments. Made from 80% post-consumer recycled material with advanced closure, dual receipts, barcoding, and numbering for full traceability. Their large format size provides maximum capacity for transporting larger documents, files, cartons and bulkier valuables where security and traceability are essential. They are available from UK stocks for quick despatch, or available customised to your requirement (MOQ's apply).

The enhanced closure system protects against a wide range of intrusion methods, including mechanical interference, temperature manipulation, and solvent exposure. Each bag features reinforced seams, providing excellent durability and reliability during demanding use. For accountability, every bag includes a unique numbering and barcoding system (Code 128, printed across the bag and both detachable receipts) to simplify tracking through handling and auditing processes. The specialised writing panels ensure that recorded details remain permanent and tamper-proof.

These oversized XL C3 size security bags are ideal for securely transporting A3 documents, bulk cash deposits, and high-value consignments. Commonly used in healthcare for large medical files and records, in retail and banking for bulk deposits, and by courier and logistics providers for oversized parcels and confidential shipments.
