In 1983, [[Costa Rica]] and [[Haiti]] issued the first [[Tyvek]] and the [[Isle of Man]] issued the first [[Bradvek]] polymer (or plastic) banknotes; these were printed by the [[ABCorp|American Banknote Company]] and developed by [[DuPont]]. These early plastic notes were plagued with issues such as ink wearing off, and they were discontinued. In 1988, after significant research and development in [[Australia]] by the [[Commonwealth Scientific and Industrial Research Organisation]] (CSIRO) and the [[Reserve Bank of Australia]], Australia produced the first [[polymer banknote]] made from [[biaxially-oriented polypropylene]] (plastic), and in 1996, Australia became the first country to have a full set of circulating polymer banknotes of all denominations, completely replacing its paper banknotes. Since then, many other countries have adopted circulating polymer banknotes, including [[Bangladesh]], [[Brazil]], [[Brunei]], [[Canada]], [[Chile]], [[Guatemala]], [[Dominican Republic]], [[Hong Kong|Hong Kong SAR (China)]], [[Indonesia]], [[Israel]], [[Malaysia]], [[Mexico]], [[Nepal]], [[New Zealand]], [[Nigeria]], [[Papua New Guinea]], [[Paraguay]], the [[Philippines]], [[Saudi Arabia]],  [[Romania]], [[Samoa]], [[Singapore]], the [[Solomon Islands]], [[Thailand]], [[Trinidad and Tobago]], the [[United Kingdom]], [[Uruguay]], [[Vietnam]], and [[Zambia]]. Other countries have issued commemorative polymer notes, including [[China]], [[Kuwait]], the [[Northern Bank]] of [[Northern Ireland]], the [[Bank of Scotland]] in [[Scotland]],<ref>{{cite web |title=And finally… Forth Bridges £20 notes enter circulation |url=https://www.scottishconstructionnow.com/articles/and-finally-forth-bridges-20-notes-enter-circulation |website=Scottish Construction Now |access-date=9 February 2025 |language=en |date=28 February 2020}}</ref> and [[Taiwan]].<ref>{{cite web |website=About Australia |url=http://www.dfat.gov.au/facts/currency.html |title=Our Currency |publisher=Australian Government |access-date=19 July 2011 |archive-url= https://web.archive.org/web/20110607104633/http://www.dfat.gov.au/facts/currency.html |archive-date= 7 June 2011 |url-status = dead}}</ref> In 2005, [[Bulgaria]] issued the world's first [[hybrid paper-polymer banknote]].

Polymer banknotes were developed to improve durability and prevent [[counterfeit]]ing through incorporated security features, such as [[optically variable devices]] that are extremely difficult to reproduce.
