  • Patent number: 11596112
    Abstract: A greenhouse screen comprising strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product. The film material comprises a highly transparent, biaxially oriented, UV and flame-stable polyester film which is provided on at least one side with a coating which reduces the reflection of visible light. The greenhouse screen is particularly suited for the cultivation of plants with high light requirements.

  • Publication number: 20210259162
    Abstract: A greenhouse screen is described with strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product is disclosed. At least some of the strips include a film material in the form of a single- or multilayer polyethylene film having a thickness of 10-70 micrometers. Said film has at least 2-4 wt.-% SiO2 particles having a D50 of 2-10 micrometers. The film is advantageously used as a screen providing light scattering properties particularly suited for greenhouse applications.
