A few days ago, GRP's new greenhouse cover film was introduced in Shanxi. Its popularization and application will greatly promote the large-scale development of greenhouses.

The inventor of the new film was Cheng Yaogui, a farmer from Qingxu County, Shanxi Province. It uses glass fiber as the main raw material, and then uses unsaturated polyester resin, alkyd thinner, rosin, methyl ethyl ketone peroxide, cobalt naphthenate and alum and other chemical raw materials.

Compared with ordinary plastic film, its biggest feature is that, when the outdoor temperature is higher than minus 16 degrees Celsius, the greenhouse does not need to cover straw. Save labor while reducing farmers' investment. Moreover, the new product has good light transmission, high mechanical strength, and good heat preservation performance, and its service life is ten times that of ordinary plastic films.
