The lifetime of a film depends on the quality and technical characteristics of the film and on the conditions of use (area, greenhouse type, installation, use of agrochemicals).
LUGUAN' range of greenhouse films includes products with a lifetime of up to 5 years, containing special combinations of UV-stabilisers and antioxidants that protect them from the harmful effect of UV light and heat for very long periods. All additive concentrates are manufactured in-house, to ensure absolute consistency in quality. UV-stabilizer formulations are based on the company's 24 years of experience and know-how in this field.
Our experience and careful selection of raw materials, processing conditions and quality control procedures provide to the films excellent mechanical strength.
A new generation of super-tough films has been introduced by LUGUAN using special high-strength polymers. These films offer additional safety in areas with very strong winds, or significant economy as they can be produced at a lower thickness than regular films while maintaining the same or still higher strength.
High light transmission is absolutely essential to plant growth. Experience in production, quality of equipment and selection of materials, ensure that LUGUAN' films have the maximum light transmission.
For areas with serious dust problem or carbon particles from industrial pollution in the air, LUGUAN avails films with anti-dust properties.
Light from the sun passing through a greenhouse film and entering a greenhouse is split into direct and diffused. Light diffusion causes a film to look hazy to human eye-this doesn't mean, however, that the film is less transparent. The PAR (photosynthetic active radiation) received by plants is practically the same.
It is now generally accepted that diffused light has a positive effect on plant growth, especially for spring and summer crops and in areas with strong sunlight.
Light diffusion reduces shadows, ensures more uniform distribution of light in the greenhouse so that it reaches even the lower parts of the plants, prevents burnings and offers a moderate cooling effect.
We have the know-how and produces films with more or less diffusion, according to the specific requirements of each area and crop:
· Crystal clear films (maximum direct light)
· Films with medium diffusion (35-50%)
· Films with very high diffusion (60-75%)
The choice of the most appropriate level of diffusion depends on the climate of the area, the crop and the season(s) of growing.
The special thermic agricultural films that we offered, contains Infra-Red additives skilfully which absorb the Infra-Red radiation and reduce heat losses during the night, which ensure a smoother fall of temperature during night and result in higher night temperatures by 2-4°C relative to common films.
Features and Benefits:
· Protection from frost and low temperature
· Smoother temperature drop and higher night temperatures overall
· Reduced energy consumption for heating
· Higher crop yield
· Earlier harvesting
· Better quality of crops
Droplets formed at the inside surface of greenhouse films due to water-condensation have negative consequences on plant quality and growth, as they reduce light-transmission by 15-30% and increase the incidence of certain diseases.
The "anti-dripping" films we are manufacturing that contain special additives which eliminate droplets and form instead a continuous thin layer of water running down the sides.
The Anti -Mist additive is used with Anti Drip 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 landscape 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 film is especially smooth and this significantly reduces the accumulation of dust.
LUGUAN has developed a range of special disease control films, which contribute efficiently in "Integrated Pest Management" and help to reduce the usage of pesticides.
An important type of disease and insects control films is "UV-blocking" films, which absorb UV-radiation up to 380 nm, thus achieving:
Features and Benefits:
• Reduction of the population of whiteflies, thrips, miners, aphids and other insects in greenhouses, thereby also reducing the viruses which are vectored by these insects.
• Control of the spread of certain diseases (such as botrytis), by reducing the sporulation of the relevant pathogenic fungi.
• Reduction of "blackening" of red rose petals, thereby increasing their commercial value.
In many areas of the world there is growing requirement for films that cut-down excessive heat during day-time and maintain a cooler environment in the greenhouse. Particularly in the "tropics", in areas with strong sunlight and hot weather as well as in nurseries and for shadow-loving ornamental plants, the "cooling effect" is becoming more and more a requirement.
We offers special types of films, which reflect and/or absorb the Near Infra-Red (NIR) Radiation, the part of solar spectrum carrying most of the heat entering a greenhouse in day-time and which is otherwise useless for plants growth, thus reducing the heat inside the greenhouse during the day. It has been demonstrated that the higher the outside temperature, the larger is the temperature difference achieved by use of "cooling" films.
We offer a range of special films incorporating selected additives and pigments to modify the light spectrum entering the greenhouse, thus changing the growth behavior of plants (photosynthesis and photomorphogenesis). By using such films it is possible to increase the yield, to promote or retard the growth and to cause elongation or dwarfing of the stems.
Features and Benefits:
1.Earlier harvesting.
2.Higher crop yield.
3.Better quality of crops.
In some of the world's most rainy regions, the air is humid and many algae begin to appear on the surface of the agricultural film. Algae can easily cause a drop in the light transmittance of the film and affect the yield of crops in the greenhouse. To solve this problem, we added special additives on the surface of the film to prevent the growth of bacteria on the surface of the film and thus inhibit the production of algae.
