Biodegradable plastic refers to a type of plastic that is degraded by the action of microorganisms in nature such as bacteria, mold (fungi) and algae. The ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and finally becomes inorganicized to become a component of the carbon cycle in nature.

      "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastic is a polymer material that has both the properties of "paper" and "synthetic plastic". Biodegradable plastics can be divided into completely biodegradable plastics and destructive biodegradable plastics.

      Destructive biodegradable plastics: Destructive biodegradable plastics currently mainly include starch modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, etc.

       Completely biodegradable plastics: Completely biodegradable plastics are mainly made from natural macromolecules (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable macromolecules, such as thermoplastic starch plastics, aliphatics Polyester, polylactic acid, starch/polyvinyl alcohol, etc. are all such plastics.

       Zhongshan Diantang Environmental Protection Technology Co., Ltd. has been committed to the research and development of biodegradable materials for many years. It has an experienced team and has nurtured fruitful scientific and technological achievements. The patented product BDS FOAM biodegradable packaging foam material (Patent No.: 201010291109.7: A starch-based fully degradable packaging material and its preparation method) is one of the masterpieces.
