| Message: | Black film is made of polyethylene as the main raw material, added with anti-oxidants, ultraviolet absorbers, black masterbatch, black plastic film for agricultural coverage produced by plastic film blowing machine. The light transmittance of this film is relatively weak, only 10%. The heat is not easily transmitted to the soil, which makes the surface temperature rise relatively slow. Therefore, the performance of preventing soil water evaporation is stronger than the colorless transparent film. The grass under it cannot perform photosynthesis and stop growing, which can significantly inhibit the growth of weeds and save weeding costs. url:http://www.greenhousesheet.com |
