Abstract

The present invention relates to a Plasticizer, which is fabricated by mixing monomers of biodegradable polymer with bio-molecules subsequently to deal the mixture with thermal treatment. The Biodegradable material comprising the Plasticizer has high melt index which is contributive for the processing of thermal processing, and the microwave-tolerance and water-resistance of the material makes the material suitable for food packaging.
