Kargil Dow Polymers first extracts unrefined natural sugar dextrose from natural crops such as corn or wheat, then converts dextrose into lactic acid, and then cold-shrinks lactate to lactide. The material is then melted with lactide to form a long molecular chain of a polymer called polylactide. By using this long-chain polylactide polymer, packaging materials can be manufactured without causing environmental pollution.
Japan uses natural plants to make packaging materials
Japan's Cargill Road Polymers has recently succeeded in making packaging materials from natural plants such as corn or wheat. This packaging material is named "Polylactide Natural Product" and can be used to make paper cups, candy wrappers, etc. It has good hand feeling, high elasticity and resistance to fouling.
