Currently, agricultural mulch films made from non-biodegradable materials such as polyethylene (PE) are widely used in many countries around the world. However, these materials have adverse effects on the environment. Used mulch films occupy large areas of land, resulting in soil pollution and damage to ecosystems. So, the development of biodegradable mulch films has been becoming an inevitable trend.
PBAT for biodegradable mulch film is a new material that has been developed to replace traditional PE mulch films. PBAT, short for polybutylene adipate terephthalate, is a fully biodegradable resin that is made from renewable resources, such as corn starch or pea starch. Compared with other biodegradable materials, PBAT has a higher degree of biodegradability, which means it can be completely decomposed into water and carbon dioxide by microorganisms in natural environments within a short period of time.
The production process of PBAT for biodegradable mulch film is more environmentally friendly than the production of traditional PE mulch films. Additionally, PBAT-based mulch films have various advantages. Firstly, they have good mechanical properties which can meet agricultural requirements and are capable of being processed into films with a thickness of less than 6 μm. Moreover, PBAT can maintain its flexibility and resistance to degradation during the planting season. Moreover, it has good water retention properties, and can improve the quality of the soil and promote plant growth.
When the PBAT-based mulch films complete their agricultural function, they can be degraded by soil microorganisms without leaving any residues, and eventually form organic matter that can return to the soil. Therefore, PBAT-based mulch films represent a sustainable and effective alternative to traditional mulch films. They can help reduce plastic waste pollution and contribute to a cleaner environment.
In conclusion, PBAT for biodegradable mulch film is a promising material that can replace traditional mulch films. The use of PBAT-based mulch films in agriculture can significantly reduce waste and pollution, promote sustainable crop growth, and protect the environment.
