Greenhouses can be defined as a controlled and ideal environment for the growth of plants that protect plants from external influences such as rain, wind and cold weather, and with a balanced environment inside, plant growth is accelerated. Greenhouses provide the possibility of harvesting more than once a year.
One of the best covers to protect these environments is plastic greenhouse covers. Semanplast (Parse) with the ability to produce all types of these covers up to 16 meters wide in different grades and also with different additives, covers with different life spans. It provides the basis of thickness and other additives according to the desired application (flower, vegetable, fruit, traditional agriculture, hydroponic agriculture, geothermal application, etc.) and the place of use.

Technical Specifications
Additional features
• Anti-dust covers
This additive makes the dust attached to the outer surface of the plastic easily removed with the help of wind and rain. Therefore, the light transmission of the greenhouse cover will remain high for a long time, thus increasing the efficiency and quality of the crops.
• EVA + IR thermal covers
The heat dispersing nylons produced in Semanplast (Parse) with EVA and IR additives at the same time keeps the heat from sunlight during the day and minimizes heat loss so that the products in protect against the risk of freezing, with a relative increase in temperature between +1 and +5 degrees Celsius, we will see the improvement of plant growth, in addition, fuel consumption will also decrease.
benefits :
Protection against freezing and low temperature
Milder temperature drop and generally higher night temperature
Reducing energy consumption for heating
Higher product performance
Early withdrawal
Better quality products
•Anti-drip covers
This additive helps reduce the fogging problem known as a side effect of greenhouse coatings at sunrise and sunset that occurs in coatings where an anti-drip additive is used. The anti-fog additive has a negative effect on the efficiency and effectiveness of the anti-drip additive, and as a result, it reduces the efficiency and shortens the effectiveness period of the anti-drip additive.
• Non-thermal covers
In areas with intense sunlight, when the weather is hot or the growth of crops requires shade, the interior of the greenhouse must be cooler than the outside, for this purpose, greenhouse nylons with a cooling effect can be produced in cement plastic, which are The mechanism of sunlight reflection, absorption and refraction prevents the increase of the internal temperature of the greenhouse during the day. Greenhouse covers with a cooling effect warm up later in the morning than greenhouse covers without this addition.
• Non-thermal covers
Transpiration in plants and the ground occurs due to the large temperature difference between the inside and outside of the greenhouse, and water droplets form on the inner surface of the greenhouse cover. These water drops prevent some sunlight from entering the greenhouse. And the rest of the sunlight that enters the greenhouse causes burning of the plants and some diseases because the water droplets act as a lens. The anti-drip additive prevents the moisture in the greenhouse from forming as significant water droplets on the inner surface of the nylon greenhouse.
benefits :
More light in the greenhouse
Higher product performance
Early withdrawal
Better product quality, higher commercial value
Fewer diseases
Reducing the need for pesticides
• Pest control covers (AV)
This additive causes the rays of sunlight to break and spread when entering the greenhouse. Therefore, it prevents plants from creating shadows on each other and protects the product from the scorching effect of the sun in sunny days. It helps the growth of plants and fruits. Depending on the type and thickness of the produced film, this additive can spread between 40 and 70% of sunlight.
