How Australia's plastic banknotes are made

Wow. Australia uses plastic banknotes that can get wet and are virtually unbreakable. In addition to making counterfeiting difficult. Would you like to see how it is done?

They had the problem of the rapid deterioration of the banknotes. In 1988 they began testing a new type of almost indestructible banknote, made of plastic.

They are his famous Polymer banknotes

Manufacturing process of plastic money from banks

It begins by using polymer grains that melt and form a plastic liquid at 120º that falls in the form of a cylindrical cascade and while it does so it is cooled with small jets of water.

With this plastic they make a bubble, the largest in the world, its size is equivalent to a 5-story building. With this, what they achieve by maintaining the pressure is that all the surface of the bubble, the entire wall has the same thickness. They get to stretch it 20 m.

At the bottom of the coil, the polymer is collected in coils and transparent film appears to wrap food.

Another technical difficulty that must be solved is how to print on plastic so that the ink does not go away.

It is painted with 5 coats of paint on each side. He is a very sticky figure. Transparent areas are left that will be like windows that are used for security issues of the bill and it is verified that they are all made with a strobe light.

Using a laser, 5 small images are burned in the window that will be an anti-counterfeiting measure.

The polymer is then cut into sheets.

It may take more than 2 years from the beginning of designing a banknote until it is put into circulation.

To pass the design that has been chosen, which is full of details to avoid falsifications, it has to be done in two steps:

Colors are first printed by passing it through a press

A second press adds another layer of color and small details

With the variation of the density of the ink the roughness is given that will allow to differentiate the authentic bills from the false ones with the touch.

With this the banknotes are almost finished but you have to add your serial number.

Once printed, they are cut and passed through a machine that will validate each ticket, checking that it has no imperfections. Before this work was done by 70 women and they chose women for the job because they thought they paid more attention to details.

This is real plastic money, ahem
