The transmittance of po film can reach about 93 percent, and the application of Po film still reaches 80 percent and 90 percent. PO greenhouse film heating quickly in the morning, good heat insulation at night, especially in the winter under the same sun exposure standard, the actual effect is more prominent; Rain and fog are more significant for continuous rainy days. Especially when there are more haze days today, the application of this kind of PO membrane is very good for the growth of plants.

Because there is a unique thermal insulation agent in the po film, most of the heat generated by the external radiation source of the arch shed is reflected back home, and the temperature is reasonably locked. The night temperature under the same standard is 1-3℃ higher than that of EVA film. It ensures the growth and development temperature of crops at night and reduces ripening. That green plants can be digested and absorbed in the condition of sufficient natural light early improvement, early sale, of course, can occupy a place in the fierce market demand.
