What kinds of plastic film do you have? Introduction to the price and function of different plastic films

In agricultural production, many tools need to be used, such as machinery and plastic film. with the development of agriculture, the types and uses of plastic film are more perfect, which are welcomed by farmers. so do you know all about the function and type of plastic film? Let's learn about it.

I. types of plastic film

There are many kinds of plastic film, mainly impervious film, geomembrane, greenhouse film, PO film, black and white film, white film, polyethylene film, longevity drip film, rain-proof cloth, silver gray film, herbicide film, grafting film, ground cloth, degradable plastic film, woven plastic film, grouting film, cold-proof cloth, forage film, scattering film, polypropylene film, hemp film and so on.

Second, the function of plastic film

1. Impervious film: impervious film is also called waterproof film in many areas. it has good heat resistance and cold resistance, toughness, high strength and good extension performance. it is often used in anti-seepage projects, such as artificial lakes, landfills, tailings treatment stations.

2. Geomembrane: it is a kind of polymer chemical flexible material, which has the advantages of corrosion resistance, low temperature resistance and good frost resistance. It is often used in landfills, sewage or waste residue treatment sites, river embankments, lake dams, tailings dams, sewage dams and reservoir areas to prevent seepage.

3. Greenhouse film: greenhouse film generally refers to plastic greenhouse and greenhouse plastic agricultural film, covering greenhouse film can provide crops with good temperature, humidity and light quality climate environment, can effectively control diseases and insect pests and reduce the impact of natural disasters, and improve crop yield and quality.

4. PO film: it has good transparency, low haze, high transparency, super tensile strength and anti-tear strength. It is mainly used to cover the outside of the greenhouse.

5. Black plastic film: the light transmittance is low, which can effectively prevent the evaporation of water in the soil and inhibit the growth of weeds. The black agricultural film is the best for cultivating summer radish, Chinese cabbage, autumn cucumber and late tomato in the plots with serious weeds or in high temperature season.

6. White plastic film: White plastic film, also known as ordinary plastic film, has a light transmittance of 90%. It is widely used to increase temperature, store water and preserve soil moisture in spring. in addition, it plays a certain role in improving soil microbial activity, soil organic matter content and soil improvement.

III. The price of plastic film

The prices of different plastic films vary. At present, the price of impervious film in Lingcheng District, Dezhou City, Shandong Province is 2 yuan / square meter, composite geomembrane 2 yuan / square meter, cold proof cloth 1.1 yuan / square meter, floor cloth 1.2 yuan / square meter, black plastic thin 2 yuan / square meter, polyethylene mulch 31 yuan / package in Jiulongpo District, Chongqing City, and 70 yuan / package of silver ash mulch in Lianshui County, Huaian City, Jiangsu Province. The price of PO film in Linzi District, Zibo City, Shandong Province is 1.5 yuan per square meter, this data comes from the wholesale price of Nongxun Network, for reference only, the actual price is based on the place of origin.

In agricultural production, plastic film is indispensable, and different plastic films have different functions, so in the process of use, we must master the uses and methods of all kinds of plastic film, and remember not to use it blindly.
