Degradable Materials for Making Agricultural Film
With the increasing attention to environmental protection, the use of degradable materials in various industries has become a trend. The use of degradable materials, especially in agriculture, has gained more and more attention.
One of the most significant applications of degradable materials is in the production of agricultural film. Agricultural film is used to cover crops, protecting them from harsh weather conditions, pests and diseases. Despite the benefits of using agricultural film, the disposal of traditional plastic film is a big issue. Traditional plastic film cannot be easily decomposed, and it can seriously harm the environment and ecosystem if not properly handled. The constant use of traditional plastic films also leads to the accumulation of plastic waste, which worsens the environmental problems that we face today.
However, the use of biodegradable materials in the production of agricultural film will help solve these problems. Biodegradable agricultural films can decay through natural temperature, light, and moisture, which significantly reduces the pollution caused by traditional plastics.
The use of degradable materials can not only solve environmental problems but also improve crop growth and yield. Biodegradable materials can ensure that crops receive an adequate amount of air and moisture. They also have an excellent effect on soil moisture conservation and improve soil fertility, enhancing the quality of the soil and the crops grown within it.
The most common degradable materials used in the production of agricultural film are polylactic acid (PLA), starch, and polyhydroxyalkanoates (PHA). These materials can undergo natural decomposition, which means that they have a minimal impact on the environment.
PLA is a biodegradable and compostable plastic derived from renewable resources such as corn starch and sugar cane. After use, it can be composted, which means it can decompose naturally in the environment. It is widely used in the production of agricultural film, as it is easy to process and produce, and has excellent physical and mechanical properties.
Starch-based films are another common material used in the production of agricultural film. The material is made from renewable resources and is easily processed and molded. The use of starch-based films can improve the soil structure and provide a better environment for the crops. Starch-based agricultural film can decompose in 6-12 months, which is significantly faster than traditional plastic film.
PHA is another type of biopolymer that is widely used in the production of agricultural film. The material is made from renewable resources such as plant matter and microorganisms, which makes it an eco-friendly option. PHA has excellent biodegradability and can be decomposed by microorganisms in the soil in a short period.
In conclusion, the use of degradable materials in the production of agricultural film is an excellent way to reduce environmental pollution and promote sustainable development. The use of these materials can lead to higher crop yields and improved soil quality, which results in better agricultural production. It is a positive step towards a more sustainable future, and we should encourage and support the adoption of this technology.
