Tamper evident bag designed for secure cash, document, and evidence transport with strong sealing and OEM customization support.
Our tamper evident bag is engineered to provide reliable protection for cash, documents, and sensitive materials during transit. This tamper evident bag uses a high-strength PE material combined with a permanent security seal that clearly shows any unauthorized opening. Therefore, it significantly reduces loss risks in banking, logistics, and evidence handling operations.
The bag delivers strong tear resistance and consistent sealing performance. However, it remains easy to use for frontline staff. In addition, clear warning messages, barcodes, and serial numbers support traceability and audit control. These features make the bag suitable for financial institutions, courier services, and government agencies.
As a factory-direct manufacturer, we support bulk orders with stable supply capacity. Moreover, we offer OEM and custom production, including size, thickness, printing layout, and branding options. This allows brands and distributors to standardize security packaging across regions. Through direct cooperation, buyers gain consistent quality control, competitive lead times, and dependable long-term production support.
