Guardian
CCL Secure (Australia)
Guardian is a hybrid banknote substrate developed by CCL Secure, combining polymer and paper technologies in a single substrate.
The Guardian substrate incorporates a polymer window within a cotton paper base, enabling advanced security features through the transparent polymer element while maintaining the familiar tactile qualities of traditional paper currency. The polymer window can accommodate sophisticated optical security devices, holograms, and other anti-counterfeiting technologies that wouldn't be possible with paper alone.
Guardian offers improved durability compared to traditional cotton paper notes, extending circulation life and reducing the frequency of banknote replacement. The hybrid construction allows central banks to achieve significant security enhancements while preserving the handling characteristics that users and cash handlers expect from paper currency.
The substrate is compatible with conventional banknote printing processes, allowing production facilities to integrate Guardian into existing workflows without major infrastructure changes. This makes it an attractive option for central banks seeking to upgrade security and durability without the operational complexity of transitioning entirely to new substrate technologies.
Guardian has been adopted by several countries looking to modernize their currency with enhanced security features while maintaining continuity in the look and feel of their banknotes. It represents a practical solution for jurisdictions where public acceptance of traditional paper currency remains strong but where counterfeiting threats demand technological advancement.
