In the past, in agriculture, when using greenhouses to grow crops, most of the vegetable greenhouse films we saw were white. In recent years, with the development of films, different colors have been produced, but most of them are blue. Blue plastic film is a commonly used color agricultural film. In addition, there are black, purple, yellow, silver gray and other colors.

Vegetable greenhouse films of different colors have different absorption and reflection effects on sunlight. Different colors also have their own different effects, such as the effects on temperature, the conditions for the occurrence of diseases and insect pests, and the growth of weeds, as well as the effects on the growth of different crops.
