Objective: to learn how to make a plastic film from potato starch
Introduction: Biodegradable plastics can be derived from many starch-based materials. In this lab, we
will make a plastic film from potato starch and test its properties. Potato starch is a polymer made of
long chains of glucose units joined together. Specifically, it contains two polymers:
1. Amylopectin – a highly branched polymer of glucose units
2. Amylose – a straight chain of glucose units
