step 1

Potatoes are 95% starch and need to be ground together with water, before the starch can be sieved away and set to dry

step 2

The starch is then mixed with a volume of hydrochloric acid and propan1,2,3-triol

step 3

Next step is to heat the mixture until boiling point

step 4

The mixture is then spread thinly and is left to dry in a controlled environment

step 5

Once dry you have a bioplastic and this is then manufactured into a polywrap

Potato starch is a polymer made of long chains of glucose units joined together. It actually contains two polymers: Amylose, which is a straight chain of glucose units Amylopectin, which is a branched polymer, also made of glucose units

The amylopectin prevents the starch from becoming plastic-like and needs hydrochloric acid to break down the amylopectin and change the structure and properties of the polymer. Propan1,2,3-triol (also known as glycerol) also needs to be used, which will act as a plasticizer.
