Mis on Greenhouse katmine Film ?
Greenhouse covering film, also known as agricultural plastic, polyethylene, poly film or greenhouse plastic, is a durable and inexpensive way to cover your little backyard hobby greenhouse or large commercial greenhouse project, it is also widely used in single and double layer greenhouse.
Optimeeritud valguse jaotus:
Diffused light reaches plants from many different angles while regular light transmission remains
samaks, optimeerides valguse jaotuse kõik osad kasvuhoonegaaside
Light from the sun passing through the covering 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 the same
Taimede päikesepõletuse:
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.
Varasem Harvest, suuremaid saake:
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.
The diffusion film is very popular all over the world, which is used widely in France, Spain, Israel, Turkey, Australia, African countries etc., because the diffusion film with uniform distribution of light is good for the plant’s phot-osynthesis.
It is proved by experiments that, regardless of planting cucumber, tomato, or flowers, the diffusion film can in-crease the yield of them
The increased yield percentage is as follows: Cucumber(4-10%),Tomato(8-10%),Mixed Sweet Pep-per(5%),Rose(5%). This increased yield is caused by the lights of Diffusion film, the Diffusion lights are going to all parts of plant, making the photosynthesis more sufficient.
UV kaitse, parem vastupidavus ja pikaealisus:
Advanced UV stabilizers maximize physical properties for the longer life of film and help protect it from chemical damage. Apart from the occasional tornado, hurricane, or hailstorm, more damage is done to greenhouse film by sunlight than any force of nature. It’s the ultraviolet component of sunlight that does the damage, resulting in yellowing and weakening of the covering film. Fortunately, you can buy greenhouse film that has built-in resistance to the damaging effects of UV radiation. If you buy a plastic that does not have UV protection, you can expect a very short service life from that poly – very possibly no more than a single year. Most greenhouse films that ARE treated with UV protection, on the other hand, have a service life rating of from 3 to 5 years.
Anti-tilguti & Tolmueemaldus
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 and increase the incidence of certain diseases, To prevent this from occurring, we use a special anti-drip (AD) additive, which flattens the water droplets into a layer of water that runs down the sides of the greenhouse. So the film with the function of Anti-Drip can 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.

Tugevamad punkteerimine ja Rebimiskindlus
An unique manufacturing process conditions and quality control procedures provide to the films excellent mechanical strength, we are using special high-strength polymers. Our advanced Japanese resin technology provide TOYOTANI’s films with superior tear strength, These films offer additional safety in critical areas with very strong winds.
100% imporditud Brand New Materials
Fenglong has 20 years experience and careful selection of raw materials, we import the additives from Japan, and other materials from USA, Japan, Iran, Saudi Arabia, to keep the film top quality.
Parem termiliste
TOYOTANI® special Multi-layer films, containing a combination of EVA and Infra-Red additives skillfully structured in the middle layers, which absorb the Infra-Red radiation and reduce heat losses throughout the night.
Premium hüdrotalkiit Materjal paremini säilida Thermicity
Eeliseid termiliste filmid on:

- Sujuvam temperatuuri langus ja suurem öötemperatuure üldine.
- Vähendatud energiakulu küttele.
- Kõrgem saagikuse.
- Varasem koristamist.
- Parem kvaliteet kultuurid.
Kuidas termilise Kasvuhoone filmide toimib?
Päeva jooksul kasvuhoonesse, päikesevalguse, koosneb nii nähtava valguse ja lühilaine infrapunavalguse, imendub taimede, pinnase ja konstruktsioonimaterjalid mille tulemusena need soojendama. Ööl kõiki objekte, mis on imendunud see energia vabastab ta nii kaua laine infrapunakiirgust. Termilise film neelavad ja kiirgavad seda energiat, säilitades suurema kasvuhoonegaaside temperatuuri ja seetõttu madalama küttekulu. Thermal filmide üldiselt maksma ise esimesel aastal ulatus
Custom Cut pikkus ja laius
Special cut lengths and width are available, so you can order the exact amount at different size according to your different greenhouse disign.
Kasvuhoone katmine Film on saadaval erinevaid paksusega üldiselt vahemikus 3 milli (0,08) kuni 8 mils (0,20), märkus: 1 mil on 0.0254mm.The paksus polü kile enamasti mõjud vastupidavus ja oodatava kasutuskõlblikku elu plastist. Samuti paksem plastikust, seda vähem valgust on edastatud läbi. Aga paksus plastist on vähe mõju pärast soojuse hulk, mida saab kaotatud plastist.
6 ja 8 mln (0,15 mm ja 0,20 mm) filmid on enamkasutatavad paksus kasvuhoone plastik.
