Biodegradable plastic refers to a material that can be degraded into low molecular weight substances by microorganisms themselves or the secretions of microorganisms under certain conditions. The U.S. Food and Drug Administration stipulates that, except for biodegradable plastics and very few water-degradable plastics that can be used in food packaging, other such as photodegradable plastics or light and biodegradable plastics fail to meet the regulations as food packaging materials.
