The temperature difference inside and outside the films used in greenhouse cultivation on the one hand and the large difference in the surface tension of the polymer film with humidity on the other hand, causes the formation of water droplets on the inner surface of the film, which is known as fog. Water droplets formed on the surface of the film not only reduce light transmission and result in slower plant growth in the greenhouse, but also the fall of these droplets on greenhouse products acts as a lens and causes severe damage such as fungus and burns in the products. Also, this phenomenon in many cases in food packaging can severely affect the quality of product packaging and cause less clarity of vision.
In order to prevent the problems caused by these phenomena, it is necessary to use anti-fog additives in film production. Considering the importance of using these materials in the efficiency of greenhouse films and food packaging, Pouya Polymer Tehran has been able to offer various types of anti-fog masterbatches with controlled migration speed and proper performance to its customers under the brand name POYAD AF.
