Tamper-evident bags with one-time security seals, barcode tracking, and OEM customization for secure cash, document, and asset handling.
Tamper-evident bags are designed to provide reliable protection for cash, documents, and sensitive items during transport and storage. These bags use a one-time security seal that clearly reveals any unauthorized opening, therefore reducing loss and improving accountability in security-critical operations.
Manufactured from durable LDPE or co-extruded plastic film, these bags offer strong tear resistance and consistent sealing performance. The transparent body allows quick visual inspection, while integrated warning text reinforces handling compliance. In addition, writable panels, barcodes, and sequential numbering support tracking and chain-of-custody management.
These tamper-evident bags serve banks, retail chains, logistics providers, and government institutions. However, applications also extend to medical samples and confidential document handling. OEM customization is available, such as size, thickness, seal color, warning text, and logo printing. Moreover, factory direct cooperation ensures stable supply, controlled quality, and flexible bulk orders. Our production lines support large-scale output with consistent lead times, making these tamper-evident bags suitable for long-term B2B procurement programs.
