Mauritius adopted polymer for this denomination as part of a broader regional shift toward substrate durability in small island economies, where humidity and handling conditions degrade cotton paper far faster than in temperate climates. Oberthur Fiduciaire's involvement is notable — the French security printer has a long relationship with Francophone and Indian Ocean issuers, and the transparent window placement on this series reflects their in-house polymer technology rather than the De La Rue or Note Printing Australia approaches used elsewhere.

P#65 spans an unusually long print window for a polymer issue, suggesting the design was not replaced mid-series despite Mauritius updating other denominations during the same period.
