Product Information
Our X-Safe Tamper Evident Bags are purpose-designed for one-time use, providing a secure and reliable method for transporting cash, confidential documents, evidence, and other high-value items. Manufactured from strong opaque white or grey multi-layer co-extruded (COEX) film, these bags offer superior strength and durability while concealing the contents from view. The non-transparent material adds a layer of discretion and deters opportunistic theft by keeping valuables out of sight.
Each bag is equipped with a high-security tamper-evident closure tape that offers advanced resistance to temperature fluctuations, moisture, and solvent-based tampering attempts. Once sealed, any attempt to open or manipulate the bag will trigger a clear visual “VOID” message on the tape, making tampering immediately noticeable. The bag’s edges also feature built-in tamper-evident markings that distort or stretch when cut, providing an additional layer of protection against unauthorised entry.
For easy handling and accountability, every bag includes writable panels for labelling or signatures, along with a unique serial number and, in most cases, a corresponding barcode for digital tracking and audit trails. Many models also come with a tear-off receipt, allowing senders and recipients to retain a reference record for verification purposes.
Ideal for financial institutions, retail operations, law enforcement, and logistics companies, ensuring that contents remain sealed, traceable, and protected throughout transit.
