Greenhouses & Tunnels Cover Films
Q.G. Sistemas de Riego represents and distributes the leading agricultural cover films brand GINEGAR for use in greenhouses and tunnels.
These advanced cover films have unique thermal, mechanical and optical properties that make them ideal for protecting crops, enhancing growth, and meeting the varying needs of growers worldwide.
The main advantages of the films are:
1. Manufactured using the new five-layer co-extrusion technology. This technique guarantees the highest level of mechanical strength, flexibility and compatibility with all the mechanical testing standards.
2. A stabilization package, which incorporates multiple materials and gives the cover films long-term durability – even in the most severe environmental conditions.
3. Special features such as Anti Drip, Anti-Virus,Light Diffusion and Anti Dust that enable a much better development of the plants, therefore better quality and higher yields.
Effect (IR)
Effect
By incorporating an IR additive, thermal cover films absorb and reflect infra-red radiation in the range of 7-15 microns (radiation reflected from all bodies in the greenhouse).
This reduces the loss of energy accumulated in the plant foliage into the atmosphere, and prevents the cooling of the foliage at night which is essential to maintaining higher foliage temperatures – especially on cold nights.
The light diffusion feature improves photosynthesis efficiency by enhancing the exposure of different plant parts to visible light. This is especially important in crops such as tomatoes, cucumbers, zucchini, pepper, roses and more. Special additives are used in the cover films to promote light dispersion, and minimal reduction of the light entering the greenhouse.In addition to improving photosynthesis efficiency, Light Diffusion cover films also help to reduce damage caused by direct sunlight to sensitive crops such as peppers and eggplants, and prevent burns.
When the relative humidity in the greenhouse rises significantly, water condensation occurs, and droplets accumulate on the cover films, plants and other objects in the greenhouse. To prevent this from occurring, we use an anti-drip (AD) additive, which flattens the water droplets into a layer of water that runs down the sides of the greenhouse. As a result and in addition to this, our Anti-Drip cover films also reduce the need for pesticides, delay the onset of diseases, significantly improve light transmission, promote early harvesting, and contribute to enhanced yield quantity and quality.
The Anti Mist additive is used with cover films to minimize the occurrence of fog inside the greenhouse. This enables maximal transmittance of light radiation in the early morning hours, contributes significantly to reducing heating costs, reduces contamination caused by diseases, improves the passage of light and also reduces leaf diseases such as phytoftora and Botrytis.
By using our advanced 5-layer extrusion technology, we can include a dust-reducing additive to the top layer of our cover films. In this manner, the upper layer of the cover films is especially smooth and this significantly reduces the accumulation of dust.
Additives are used to significantly reduce the damage caused by low temperatures and viral diseases transmitted to the plants by various insect pests. This also significantly reduces the proliferation of foliage diseases, especially botrytis, as well as the “blackening” of red rose petals. As a result, the use of fungicides and pesticides can also be significantly reduced.

Mulch Films
Q.G.'s mulch films are advanced multi-layer films that are manufactured using two methods: multi-layer blow film co-extrusion and cast (flat die) extrusion. Offering UV protection, these films are availbale either embossed (cast) or smooth (blown) and in a wide range of thicknesses and widths according to growers´ needs, specifications and crops.
The cast production method involves embossing while the material is hot, thereby changing the surface of the sheeting and endowing it with greater flexibility, softness and strength. This allows better adherence of the sheeting to the ground surface, and is particularly suitable for crops grown on raised beds. Our agricultural cover films are manufactured using a five-layer co-extrusion technology. This enables to process raw materials that guarantee the highest level of mechanical strength, flexibility and compatibility with all mechanical testing standards.
Types of Mulch Films:
1. Black - black films absorb and block radiation to suppress weed germination. As they absorb radiation, they warm up and heat the soil, and during hot seasons, may overheat result in burning, seedlings to collapse and hyperthermia in fruit.
2. Black/Silver and Black/White - These three-layered films are silver or white on the side facing up and black on the side facing down. Silver or white color reflects radiation to prevent the overheating of seedlings, plants and fruit, enhances photosynthesis and repels pests; and the black color prevents the penetration of light and reduces the germination of weeds.
These films are recommended for vegetables, flowers and orchards with single row layouts or for the entire width of greenhouse gables. They are also available with wider widths for wider greenhouse coverage (4-9 meters).
3. Brown/Yellow - These films are yellow on the side facing up and brown on the side facing down. The yellow color attracts pests (mainly tobacco whiteflies), and studies done by Israeli researchers have shown that the use of these films significantly reduces the chance of viral diseases being transmitted by tobaco moths to multiple crop types. The brown color reduces radiation transmission and weed germination.
These films are recommended for growing summer vegetables.
4. Brown/Silver - These three-layered films are silver on the side facing up and brown on the side facing down. The silver color reflects radiation to prevent the overheating of seedlings, plants and fruit, enhances photosynthesis and repels pests; and the brown color reduces radiation transmission and weed germination.
5. Al-Or Brown -combine two properties: radiation transference in the NIR range, which contributes to the heating of the soil, and radiation blocking in the PAR range, which reduces weed germination in a similar manner to opaque films. These films are especially suitable for crops that grow in autumn, winter and early spring and in areas prone to weed growth.
Mulch films block radiation to supress weed germination.
The combined used of mulch films and drip irrigation improves water dispersion and contributes to mantaining consistent levels of moisture in the soil. In addition, darkness under the mulch "raises" root development upwards towards the ventilated upper layer of soil, where in the presence of oxygen, their activity is more efficient. Mulch films reduce water evaopration, thus saving water usage.
Reflective films (silver) repel harmful pests, specifically leaf aphids and thrips. Yellow mulch films attract moths and reduce their adhesion ability.
Transparent or opaque mulch films help retain heat and raise the temperature of the soil , which is extremely important in autumn , winter and early spring. Opaque films (such as black/silver) reduce the day-night temperature fluctuations in the soil, and black/silver and black/white reflect the light and enhance photosynthesis. These mulch films are suitable for hot seasons.
In open areas, fertilizers may be diluted in the root zone area (specifically in high precipitation microclimate and rainy regions) . The use of mulch films prevents this from ocurring. However, the mulch films also prevent the removal of salts that accumulate around the root area after rainfall.
