The micro-bubbles ensure the cooling effect which is the result of the reflection and diffusion of light on and through the film, and of the absorption of short IR by the film. This reduces the greenhouse effect. The advantages are a lower evapotranspiration and a better photosynthesis, which improves the quality and the yield of the crops. EVA or thermal minerals ensure a high thermal efficiency. Loss of warm from the greenhouse to the air is reduced. During the day, solar rays (short I.R) enter the greenhouse and warm the internal air and the soil. During the night, the greenhouse gets colder and the heat stored in the soil is released by long IR.
By spreading solar rays, a diffusing film is the best choice for crops sensible to direct light or high crops by avoiding shadows. Photosynthesis is optimized and burns are reduced, as well as phototropism. The film looks hazy but the PAR (Photosynthetic Active Radiation) received by the plant remains the same. This film contains a UV stabilizers combination and antioxidants in order to protect it against solar radiations.
This film contains specific additives which permit to modify the quantity and the quality of the Light Transmission in order to create a shadow effect. This permits to reduce the greenhouse internal temperature and (according to the shadow effect rate) to reduce or avoid the use of shadowing painting in the strong sunlight localizations.
