How long does it take for the plastic film to degrade completely?

Due to the increasing awareness of the harm of disposable non-degradable plastic film, the country has introduced a variety of land protection policies. For example, with subsidies, people can use biodegradable or fully biodegradable plastic film to reduce their pollution. Below, we'll show you how to use this biodegradable mulch and analyze how long it will take for it to be completely degradable.
 

Application description of biodegradable material mulching film:
 

One is the difference between degradable plastic film and ordinary plastic film.
 

Compared with ordinary mulching film, the global fully degradable mulching film has little difference in use. It can be laid mechanically or manually, with the same effect of heat preservation and moisture replenishing.
 

The main differences are as follows :(1) fully degradable mulching film can be determined through the technology of rupture time, without manual picking, in the natural environment can be naturally degraded into water, carbon dioxide and soil fertility, will not affect the next cultivation, will not cause pollution.
 

Types of fully degradable plastic film.
 

The choice of degradable plastic film varies by region and crop. The plastic support centre is ready to test crops such as garlic, tobacco, cotton, peanuts and potatoes, tailored to the crop and the area where it is grown.
 

Application of fully degradable mulching film.
 

Because degradable mulching film is a customized product, it needs to be applied to the corresponding crops within the specified time according to the instructions to ensure that the degradable mulching film can work normally and degrade on time.
 

Degradation process of completely degrading plastic film.
 

The degradation process of degradable mulching film was divided into three stages: induced cracking, cracking, cracking and film-free cracking. After being used, it could be ploughed directly into the soil without affecting the growth of next crop.
