Red fluorescing additives improve greenhouse film. (Extrusion).A line of inorganic inorganic /in·or·gan·ic/ (in?or-gan´ik) 1. having no organs. 2. not of organic origin. in·or·gan·ic n. 1. luminescent lu·mi·nes·cent adj. Capable of, suitable for, or exhibiting luminescence. [Latin l  men, l additives are said to increase the transmission of red light (600-700 nm), through clear greenhouse film and protect the film from uv damage. Ksanta additives from Ranita Europe AG in Regensburg, Germany, absorb uv light and re-emit it as red wavelengths of about 620 nm. Additional red light promotes plant growth and improves crop yields, Ranita says. The red-light fluorescing additive additiveIn foods, any of various chemical substances added to produce desirable effects. Additives include such substances as artificial or natural colourings and flavourings; stabilizers, emulsifiers, and thickeners; preservatives and humectants (moisture-retainers); and can also be used in packaging films to protect products from uv damage. Ksanta is based on research at the Russian Academy of Science in the early 1980s. It was originally developed for a Russian processor that made RedLight Agrofilm using the Ksanta additive. In 2000, Ranita Europe was set up in Germany to market the additive globally Ksanta grades are formulated for PC, PP, PET, PVC PVC: see polyvinyl chloride.
