Film for greenhouses SVETLITSA ™

Additive	Purpose
UV	The UV additive stabilizes the film and prevents it from breaking under the influence of ultraviolet rays
IR	The infrared additive allows you to maintain the temperature inside the greenhouse
AF	The antifog additive attracts moisture, so no drips form in the greenhouse
EVA	Properties of the EVA copolymer film:      high strength, resistance to punctures and cracking, rubber-like, service life up to 7 years without removal for the winter.
mLLDPE	Properties of a film with metallocene linear polyethylene: high strength, wind and hail resistance,

SVETLITSA™ greenhouse film

The SVETLITSA ™ copolymer greenhouse film is a durable, frost–resistant material based on polyolefins (EVA, mLLDPE, etc.). SVETLITSA™ remains in service on greenhouses for at least 7 years, even in regions with difficult climatic conditions.

Greenhouse film efficiency

The light transmission in the greenhouse under SVETLITSA™ film is higher than under its polyethylene counterpart. The light transmittance in photosynthetically active radiation (PAR) is up to 92%.

Spectral characteristics of SVETLITSA™ film 

The characteristics are optimal for growing sprouts, vegetables, as well as fruits, flowers, and seedlings. The transmission coefficient in the area of hard ultraviolet radiation can be adjusted from 0 to 88%.
For the cultivation of shade-loving plants, a reflective, light-scattering greenhouse film is designed SVETLITSA™ LIGHT REFLECTIVE.

Hothouse film production

• The film withstands hail, sudden temperature changes,  harsh, and snowy winters. Even in severe frost, the SVETLITSA ™ greenhouse film retains elasticity. Snow can be removed from the surface of the greenhouse without tearing the film. 
• The surface of SVETLITSA™ film is hydrophilic, and its contact angle is 45 - 55°. (For low-density polyethylene films it is 70-84°). Condensation droplets form flat and shallow, flowing down the walls of the greenhouse rather than dripping.*
• The SVETLITSA™ greenhouse film has an excellent heat-retaining effect. The transmittance in the region of thermal radiation is 35 - 39%. The temperature in the greenhouse at night and during the cold snap is 2-4°C higher than under the polyethylene coating. The microclimate is better than under ordinary polyethylene films, creating conditions for increasing yields.

SVETLITSA™ greenhouse film properties

1. During the operation of the SVETLITSA ™ greenhouse film, unlike polyethylene, numerous small cracks are not formed, gradually filling with dust. It is significantly less dusty, without losing the ability to transmit light. 
2. SVETLITSA™ film covers both large agro-industrial greenhouses, and small hothouses in Russia (from the western regions to the shores of the Pacific Ocean, from the Arkhangelsk region to the shores of the Black and Caspian seas), Belarus, Kazakhstan, Kyrgyzstan, Latvia, and Slovenia. 
3. Film for greenhouses SVETLITSA™ has been tested and received positive results in St. Petersburg State Agrarian University, All-Russian Research Institute of Floriculture, and subtropical crops of the Russian Academy of Agriculture (Sochi), in agrarian complexes of Russia, Belarus, Kazakhstan, Kyrgyzstan, and Slovenia. 
4. For the development of SVETLITSA ™ films and participation in exhibitions, "NPF "SHAR" has been awarded more than 50 diplomas from various exhibitions..
5. SVETLITSA™ film is certified.
6. Perennial high-strength copolymer greenhouse films SVETLITSA ™ are always in stock by the company.
7. Durability of SVETLITSA™ greenhouse film
8. The service life of the film is at least 7 years. The key to the durability of the SVETLITSA ™ film is proper installation and operation as well as the absence of abnormally aggressive external factors.
