Have you ever seen money before? You know how it's made out of paper, right? Well, some countries have made their money stronger and harder to copy by making them out of special paper called polymer!
A hybrid paper-polymer banknote is a special kind of money that is made with both paper and polymer materials. It's like when you mix two different colours of paint to make a new colour!
Using both paper and polymer together makes these banknotes harder to counterfeit, which means it's harder for people to make fake money. The paper part of the banknote makes it feel like real money, while the polymer part makes it stronger and more resistant to water and tears.
So, essentially, hybrid paper-polymer banknotes are made of two different materials to make them harder to copy and more durable for everyday use!
