The main ingredients of degradable plastic bags

Bio-degradable plastic refers to plastics that cause degradation by the role of microorganisms such as bacteria, mold (fungi) and algae that exist in nature. The ideal biodegradable plastic is a component of high molecular materials that can be completely decomposed by environmental microorganisms after abandoning, can be completely decomposed by environmental microorganisms, and eventually become inorganic. “Paper” is a typical biodegradable material, and “synthetic plastic” is a typical polymer material. Therefore, biodegradable plastic is a polymer material with the nature of “paper” and “synthetic plastic”. Biodegradable plastic can be divided into two types: complete biodegradable plastic and destructive biodegradable plastic.

Destroy biodegradable plastic:

Destructive biodegradable plastic currently includes starch modification (or filling) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, etc.

Complete biodegradable plastic:

Complete biodegradable plastic is mainly made of natural polymer (such as starch, cellulose, chitin) or agricultural and sideline products. , Starch/polyvinyl alcohol, etc., are such plastics.
Classified from raw materials, at least the following types of biodegradable plastic:

1. Polycin (PCL)

This plastic has good biodegradability, and the melting point is 62 ° C. The microorganisms that decompose it are widely distributed under the conditions of joy or qi. As a biodegradable material, it can mix it with starch and cellulose materials or convergence with lactic acid.

2. Polycorite dilate glycol (PBS) and its co -polymers

The technology of manufacturing various polymer polyester based on PBS (melting point is 114 ° C) has reached the level of industrial production.

3. Polycine (PLA)

The production process of polystrack acid has been relatively complete, and the glucose in corn can be made of Polys Tumin.

4. Polycroxyxate (PHA)

Bio -degradable plastic obtained by renewable resources, mixes the fatty people polyester and starch together, and the technology of producing degradable plastic has also been successfully studied.

5.The aliphed fragrance group polyester

The confused common polyester (ECOFLEX) of the aliphed aromas, the monomer is: hexeric acid, phenyl acid, 1,4-butanol.

6. Polyvinyl (PVA) biodegradable plastic

Mainly add PVA to the starch, which can blow the film and process other products. Polyethylene glycol materials need to have good biodegradation performance after a certain modification.

7. Carbon dioxide cluster

The earliest countries that studied carbon dioxide clusters were mainly Japan and the United States, but there have been no industrialized production.
