Environmental protection industry is a rare opportunity for fully degradable plastic materials

What are the problems with conventional films using non-degradable plastics?

At present, non-degradable plastic membrane is widely used in agricultural production, which has obvious heat preservation and moisturizing effect, but it needs a lot of manual cleaning after use, which takes a long time. Non-degradable plastic non-removable waste film remains in the soil, causing six major problems:

1. Residual film of crops is produced unconsciously on crops. The results showed that wheat, maize and cotton yields decreased by 17.8%, 13.2% and 16%, respectively, when the residual of mulching film in soil reached 120 kg/ha.

2. Residual film worsens the physical and chemical properties of soil, affects the root of crop roots, and monopolies are easy to occur when seedlings are insufficient after sowing.

3. Residual film causes serious pollution to soil and environment, and farmland fertility decreases;

4. The residual film on the soil hinders the operation of the tillage machinery and makes the tillage layer shallower, which seriously affects the crop yield.

5. In the growth and expansion process of underground tuber crops, residual film is easy to be mixed with residual film in the soil and coated with residual film, causing quality problems of agricultural products.

6. Some crop stalks. It is not easy to remove the entanglement of waste plastic film, and cattle are easy to die after being fed as fodder.

The environmental protection industry is also a rare opportunity for fully degradable plastics.

The ban on plastic bags has been in effect for 10 years since 2018, but the effect has not been satisfactory. On the contrary, it supported many ordinary plastic bag manufacturers, and many small workshops and factories took advantage of the trend to quickly occupy the market with low prices.

At this time, the relevant departments of the state also realized that "plastic limit order" is worthy of the name, to rectify and adjust. First, the country strictly grasps the green environmental protection, the second is the plastic bag product also cannot completely prohibit.
