Specifications of plastic films of Shimi Plastik Company

Controlled light transmission

Direct sunlight causes part of the planet to be exposed and the other part withers due to insufficient light. Additives that scattering direct sunlight, create a more homogeneous light in all areas of the greenhouse. This increases the emission of light to reach plants, reduces the amount of plant burning rate and increases light transmission to reach the lower leaves. This feature is especially important for broadleaf products. Research shows that the proper diffusion and distribution of light in the greenhouse reduces the spread of fungal spam and the proliferation of pests.

Purposeful light diffusion

Some farmers substitute their greenhouse plastics for only a few percents more sunlight during the short winter days. Greenhouse films produced by Simi Plastic Yazd Company absorb or reflect specific sun wavelengths. these films promote better plant growth, prevent pests from the entrance into the greenhouse, diseases, improvement, and impact on flowers. Overall, efficient and high light diffusion is one of the important factors in plant growth. Using experience in production, the equipment with the best quality, and the best and right materials, make greenhouse films of Shimi Plastic Company make sure to deliver the highest light diffusion efficiency.

Pest and disease control effect

The human eye is sensitive to UV radiations of 400 to 700 nm, while insects are sensitive to UV radiations of less than 400 nm. Greenhouse films produced by Shimi Plastic Company with their special combination, absorb the essential UV radiations that insects need for guiding and navigating. This action significantly reduces the insect’s entrance into the greenhouse and as a result of the various disease, they bring with themselves. It also makes insects that have less activity to the greenhouse in any way. Another feature of these films is to bring more financial savings for the farmer and the greenhouse keeper because they do not need to buy expensive or specific pesticides.

Prevent dust accumulation

One of the obstacles to efficient light transmission is the accumulation of dust on plastic film in the greenhouse. The accumulation of dust on the outer surface of the plastic film prevents complete and permanent light transmission and has long-lasting effects on the greenhouse environment and most important on the growth of greenhouse plants. The agricultural plastic films of Shimi Plastic Yazd Company cause the maximum rate of light transmission and also, they allow it to remove the dust easily and effectively from the outside of the greenhouse in a minimal amount of time by using the agricultural experiences as well as the best additives.

Anti -Fog effects

 When the temperature decreases and relative humidity reaches saturation, fog is formed in the greenhouse. the formed fog in the greenhouse harms the plants as the leaves are exposed to a thin, damp layer (up and down). Thereby, the fog blocks the sun radiations for hours after sunrise. These water droplets from the fog act like a lens and burn some parts of the plant. Shimi Plastic Company by using the appropriate additives in the production of plastic films for the greenhouse ensures that the greenhouse is not exposed to fog and that the sunlight is transmitted perfectly.

Thus, the growth rate of the cultivated crop increases and the time reduce for crop preparation

Anti -Drip effect and minimize moisture

Due to the difference in temperature between inside and outside the greenhouse especially at night, humidity and small water droplets in the greenhouse can be created, which can have some negative effects on the plant such as disease in cadence due to drop leakage, reducing 15 to 30 percent of the light transmission into the greenhouse as well as the quality and amount rate of the crop. To solve this problem, the greenhouse films of Shimi Plastic Company eliminate droplets and create a thin layer of running water on one side of the plastic film by adding special additives to its plastic films. Besides, the benefits of achieving more light in the greenhouse, reducing crop growth time, reducing plant disease and so on can be achieved with the principal use of these plastic films.

Reduce night heat losses

Plastic films of Shimi Plastic Yazd Company prevent light from escaping from the greenhouse by using the IR additive and combining it with the latest world technologies. These films absorb infrared radiation and reduce heat loss during the night. In places with hot temperatures, the stored energy in the greenhouse is measured between 10 and 20 percent with regards to a cloudy or clear sky. Research has shown that infrared radiation can increase plant color or density rates and accelerate crop growth. This is most likely due to the rising temperature of the plant at night.

Reduce day heat

In areas with intense sunlight, blocking part of the infrared radiation’s entrance can lower the inside temperature up to 10 degrees Fahrenheit. This action causes to exist in a cooler environment in the greenhouse, especially in a tropical environment, the “cooling effect” is a constant need for shade-love ornamental plants. The Shimi Plastic Company by adding the right color and compounds of its plastic films’ composition, makes s to reflect and absorbs infrared radiation that is not used for plant growth. The most benefits of using these films are reduce cooling costs, more workers comfort, less need for irrigation, reduce plant stress and improved fruit and final product taste.
