polymer bank note type, BOPP printing

I would like to print some waterproof certificates using polymer bank notes as the design and material influence. Like the Australian currency below. The material used is BOPP, bi-axially oriented polypropylene. I am assuming flexographic printing and UV coating like package labels.

Anyone have any tips, suggestions, or printers to steer me towards?


The Royal Australian mint http://www.ramint.gov.au/ prints polymer note currencies for other countries as well (as well as colour coins!).

Might be able to help, but I doubt they’d give out much info, if you are not a central bank then to them you are a counterfeiter.
