Cooling film is a film that will lower greenhouse temperatures in the daytime heat. It is the highly diffusing greenhouse film that improves growing conditions by using controlled diffusion to influence the light reaching the plant. It is designed to make more light available to plants by increasing the amount of diffused light to close to the maximum, while reducing short wave infra-red radiation and enhancing useful light in the PAR range.
Principle of cooling function：
By adding special nano-layer rare earth materials, it can reflect or absorb near-infrared radiation (NIR), which is a part of the solar spectrum. It absorbs most of the heat in the greenhouse during the day and reduces the temperature in the greenhouse without affecting Visible light required for photosynthesis in plants.
Features：
Reduce the temperature in the greenhouse
Applicable areas:
Tropical areas and nursery and shade-loving ornamental planting areas
Experiments have proved that under the same conditions, 120micron cooling film can reduce 3-4 ℃ in the greenhouse, as shown in the picture below:
