Diffuse Scattering Film

Product Overview

The diffuse scattering film is a functional agricultural greenhouse film specially developed for farming applications. Its core function is to convert direct sunlight into soft, diffused light, fundamentally improving the lighting conditions inside the greenhouse. This product effectively reduces sunburn damage to crop leaves and fruits while enhancing overall light uniformity within the greenhouse and minimizing differences in light exposure between the upper and lower layers of the plant canopy. Depending on cultivation needs, this film can be compounded with additional features such as cooling, heat preservation, and anti-fogging/drip prevention, making it suitable for diverse regional and crop-specific growing environments. Currently, similar products in the industry typically have a haze level of 40–65% and a light transmittance exceeding 90%, ensuring ample illumination while enabling precise control over light distribution. Customized pricing is available, and manufacturers offer one-on-one solution quoting services to meet the specific requirements of various cultivation scenarios.

Core Functional Principle

The core functionality of the diffuse scattering film is based on optical scattering principles. The special internal structure of the film refracts and scatters incoming direct sunlight, transforming concentrated parallel beams into evenly dispersed scattered light in all directions. This conversion prevents localized scorching caused by intense direct sunlight, while allowing diffused light to penetrate deeper into the middle and lower layers of the plant canopy, addressing the issue of excessive light exposure at the top and insufficient light at the bottom—a common problem with traditional greenhouse films. As a result, light distribution throughout the entire canopy becomes more uniform. When combined with anti-fogging and drip-prevention functions, the film further safeguards stable lighting conditions even in high-humidity environments by preventing water droplets from obstructing light transmission and reducing fog formation inside the greenhouse. If equipped with cooling or heat-preservation features, the film’s optical properties enable rational temperature regulation within the greenhouse, narrowing diurnal temperature fluctuations and providing a more stable thermal and light environment conducive to crop growth.

Addressed Industry Pain Points

This diffuse scattering film specifically addresses several common challenges faced in agricultural greenhouses:
1. Sunburn Issues: Alleviates problems caused by excessively strong direct sunlight during summer months or in high-altitude areas, which can lead to leaf and fruit sunburn, thereby reducing crop damage and preventing yield losses and quality degradation.
2. Uneven Light Distribution: Resolves the longstanding issue of uneven light distribution beneath traditional greenhouse films, where upper-layer leaves may suffer from excessive light while lower-layer leaves remain underexposed, improving overall photosynthetic efficiency and increasing yields.
3. High Fruit Cracking Rates: Tackles the problem of elevated fruit cracking rates resulting from large temperature fluctuations and uneven lighting, reducing cracking rates by 30–50% and significantly boosting the commercial value of crops while minimizing economic losses for growers.
4. Excessive Diurnal Temperature Variations: Mitigates sharp temperature swings between day and night, narrowing intra-greenhouse temperature differences to within 8°C and providing a stable thermal environment that protects crops from sudden temperature changes and their adverse effects.
5. Fog and Water Droplet Problems: Through integrated anti-fogging and drip-prevention functions, addresses issues of water droplets forming on film surfaces and fog obstructing light transmission in humid conditions, ensuring stable lighting and preventing weakened plant growth caused by insufficient illumination.
