It is well accepted that diffused light has a positive effect on plant growth, Light diffusion characteristics greatly improve photosynthesis efficiency by improving light dispersion. Do not affect the total quantity of light that is passing through the film.  

The advantages of diffusion films are:

It reduces shadows and ensures more uniform distribution of light, especially important for self-shading, tall and trellised plants. While the total amount of PAR (Photosynthetic Active Radiation) received by the plants remains the same.

In the area with strong sun radiation, Diffusion can give cooling effect to prevent burning of crops.

The appearance of diffused film is considerably different than standard polyethylene film. This is due to the diffusion (scattering) of light through the film. Plants utilize diffuse and parallel light, while our eyes “see” mostly parallel light. This causes a diffused film to look dark and hazy compared to a “clear” film, even though the total light transmission remains the same.

CPT design transparent 5-layer diffused film with high EVA content.

High light transmission: 92% almost as good as clear film.  

Diffused Film (1)

High diffusion: customization up to 90%,.

Excellent mechanical properties.

Anti-dust effect for continuous higher light transmission.

Anti-dripping for more light and less humidity.

High thermal efficiency which limits the heat loss.
