Shading plastic shade referred to as shade to polyolefin resin as the main raw material, is a high strength, anti-aging of the new agricultural covering material. At present, Guangdong, Shanghai, Jiangsu, Beijing and other provinces have production, of which the second largest Changzhou Wujin Plastic Factory output. Now in the vegetable production test demonstration and promotion of application, and the rapid development. In 1989, 3 million square meters of shade net were used to cover 15,000 mu of vegetables.
