An Introduction to the Types, Prices and Uses of Plastic Film
In agricultural production, many tools are needed, such as machinery and plastic film. With the development of agriculture, the types and usage of plastic film have become more refined, and it is very popular among farmers. So are you clear about the uses and types of plastic film? Let's take a look below.
I. Types of plastic film
There are many types of plastic film, mainly including anti-seepage film, geomembrane, greenhouse film, PO film, black mulch film, black-and-white film, white mulch film, polyethylene mulch film, long-life anti-drip film, rainproof cloth, silver-gray mulch film, weed-control mulch film, grafting film, ground cloth, degradable mulch film, woven plastic film, grouting film, cold-proof cloth, forage film, scattering film, polypropylene mulch film, hemp mulch film, and so on.
II. Uses of plastic film
1. Anti-seepage film: Anti-seepage film is also called waterproof film in many areas. It has good heat resistance and cold resistance, and has the advantages of toughness, high strength and good extensibility. It is often used in anti-seepage projects, such as artificial lakes, landfill sites and tailings treatment stations.
2. Geomembrane: It is a polymer chemical flexible material with the advantages of corrosion resistance, low-temperature resistance and good frost resistance. It is often used in landfill sites, sewage or waste residue treatment sites, river embankments, lake dams, tailings dams, sewage dams and anti-seepage in reservoir areas.
3. Greenhouse film: Greenhouse film generally refers to plastic greenhouses and greenhouse plastic agricultural film. Covering with greenhouse film can provide crops with a good climate environment in terms of temperature, humidity and light quality, effectively prevent and control pests and diseases, reduce the impact of natural disasters, and improve crop yield and quality.
4. PO film: It has very good transparency, low haze, high clarity, and super tensile strength and tear resistance. It is mainly used as the outer covering film of greenhouses.
5. Black mulch film: It has low light transmittance and can effectively prevent the evaporation of water in the soil and inhibit the growth of weeds. For plots with severe weeds or when cultivating summer radish, cabbage, autumn cucumber and late tomato in high-temperature seasons, black agricultural film works best.
6. White mulch film: White mulch film is also called ordinary mulch film, with a light transmittance of 90%. It is widely used for warming in spring and storing water to preserve soil moisture. In addition, it has a certain effect on improving soil microbial activity, soil organic matter content and soil improvement.
III. Prices of plastic film
Different plastic films have different prices. At present, in Lingcheng District, Dezhou City, Shandong Province, anti-seepage film is 2 yuan/sq m, composite geomembrane is 2 yuan/sq m, cold-proof cloth is 1.1 yuan/sq m, ground cloth is 1.2 yuan/sq m, and black plastic film is 2 yuan/sq m. In Jiulongpo District, Chongqing City, Chongqing, polyethylene mulch film is 31 yuan/pack. In Lianshui County, Huai'an City, Jiangsu Province, silver-gray mulch film is 70 yuan/pack.
