The Sustainability Argument
Overview
Plantic Technologies Limited currently utilises chemically modified high amylose corn starch as its primary
polymer in the manufacture of biodegradable plastics.
The basics
Starch is made up of glucose molecules linked together to form amylose and amylopectin. Most plants
naturally contain about 20-25% amylose, but some, like certain species of maize (corn) starch have more
than 50% amylose. The starch from this high amylose corn is commonly used in textiles, gum candies,
cosmetics, pharmaceuticals (generally as a coating), biodegradable plastic products, numerous industrial
applications and foods as an additive to increase the level of dietary fibre and lower the rate of energy
release without changing the taste or texture. High amylose corn has amylose content between 50% and
90%. More information is available in the download below.
