The role of biodegradable film plus plasticized starch

The functions of biodegradable mulch film plus plasticized starch are to reduce the degradation speed of biodegradable mulch film, to improve soil quality, to reduce pollution, to improve the air permeability and mechanical properties of biodegradable mulch film, and to reduce cost.

1, improve the degradation speed of biodegradable film: adding plasticized starch can reduce the crystallinity and molecular weight of biodegradable film, thus increasing the decomposition speed of microorganisms on it and promoting its rapid degradation and decomposition.

2. Improve soil quality: biodegradable mulch film with plasticized starch will release more organic substances after decomposition, improve soil structure, increase soil aeration and water permeability, and enhance soil fertility, which is conducive to the growth of crops.

3, reduce pollution: biodegradable film with plasticized starch can be decomposed into carbon dioxide and water by microorganisms, which will not cause secondary pollution to the environment and meet the requirements of sustainable development.

4, improve the air permeability and mechanical properties of biodegradable film: adding plasticized starch can improve the softness, toughness and tensile strength of biodegradable film, making it easier to operate and use.

5, reduce costs: biodegradable mulch film with plasticized starch has lower production costs, and compared with traditional PE mulch film, it has obvious advantages in degradation speed, performance and environmental protection.
