The document and file security bag is designed for secure transfer of IDs, files, and important documents. Made from high-strength composite film, it features tamper-evident sealing. Once illegally opened, a clear "VOID" mark or irreversible damage appears, preventing document swapping or unauthorized access.
It offers excellent tensile strength, puncture resistance, and heat seal strength to protect contents from damage. The bag is semi-translucent or transparent for quick visual inspection. The surface supports printing of logos, warnings, serial numbers, and barcodes/QR codes for full traceability.
Widely used in personnel file management, education authorities, law firms, and more. Ideal for file transfer, document mailing, and exchange of important papers — a professional solution for secure document and archive transfer.
