PVC greenhouse film is an essential material for modern protected agriculture, favored for its outstanding thermal insulation, light transmission and weather resistance. It is mainly used for covering greenhouses, arch sheds and other agricultural facilities, effectively regulating the temperature and humidity in the shed, promoting the photosynthesis of crops, and helping to realize off-season planting of vegetables, fruits and flowers. The film has good wind resistance, corrosion resistance and easy forming performance, can withstand harsh outdoor environments such as strong sunlight, rain and low temperature, and has a long service life. It plays a key role in improving crop yield and quality, reducing planting costs and promoting the modernization of agricultural production.
