This video illustrates how plastic is made from corn. Corn plastic is a kind of polylactide, or PLA, plastic. Polylactides are made from the resin of corn and other plants. Polylactides are biodegradable but also more fragile and expensive to make than many synthetic plastics. In the US polylactides have been approved for use in food packaging.
