Greenhouse Cover Film
Diffused Film (UV protect diffused film)
Cooling Diffused Film
These multi-layer greenhouse films are produced from state-of -the-art machines with the high technology and quality control by highly experienced R&D team. The film has excellent mechanical strengths, optimum light transmission, and good pesticide resistance which make it perfect for protecting crops and enhancing growth.
“VSC Agricultural Films” are researched & developed by experienced agronomists, polymer technology and engineering along with end users’ requirements which allow us to promote unique formulations that fulfill customer’s need. Our expertise in this field allow us to provide many types of greenhouse film solutions to match properly with growers’ need worldwide.
Diffused film generates better and more light distribution without decreasing % light transmission especially in photosynthetically active radiation (PAR) between 400-700 nm.
It is suitable for hot climate areas to prevent burning spots on leaf/flower from strong direct sunlight. This has proven positive for the cultivation of flowers and some horticultural products such as carnations, roses, safflowers, salad, tomatoes and cucumbers.
Benefits of diffused greenhouse film:
Researchers found that insect flight behavior depends on light wavelength, or spectrum. In fact specific light wavelengths can repel insects, causing them to fly away. The net therefore reflects the wavelength the insects use for vision. The net practically "dazzles" and blinds the insects, thus repelling them. The insects continue flying and avoid landing on the growth house. By creating conditions to avoid contact of insects with the net, penetration levels are considerably reduced. Test have shown that OptiNet® achieved five times less pest penetration, compared to a standard 50- mesh net.
to protect against thrips
Reduced development of leaf diseases, such as late blight of tomatoes
Insect pests damage crops and transmit diseases
anti-virus film provides better crop yields
Water droplets formed on the inside surface of greenhouse films due to water condensation and also from the difference temperature between inside and outside of the greenhouse. These have the negative effect on the plant condition and growth as droplets reduce the light transmission by 15-30% and increase the incidence of diseases. Drip protection greenhouse film contains anti-dripping additive which eliminate droplets drop directly to the plants but turn them into the thin layer of water and run down the sides of the greenhouse roof and wall.
Benefit of anti-dripping greenhouse film:
algae on the greenhouse film which significantly decrease light transmission
After using the greenhouse film for more than a year or over, it is probably that the film may be covered with some microorganism that reduce the effectiveness of the film by limit the light transmission to the crop inside. Greenhouse film with anti-microbial additive works by inhibiting the growth of microorganism (yeast, algae, fungi, bacteria) on the film so the film stays clear and clean. This additive is working by staying in the layer of the plastic and work as long as the lifetime of the plastic.
VSC PhotoSelective film is our new product in agricultural line.
Since each plant has a different requirement, it is necessary to grow them in a suitable environment for the best yield.
Benefits of PhotoSelective film:
1. Ripening and add more nutrient to the plant: due to each plant needs different wavelength to grow using our photoselective film can reduce or cut out some dangerous wavelength and receive only the necessary one that support the growth such as chili that can create more chemical for the better taste (more spicy).
2. Reduce the harmful wavelengths such as Ultraviolet or Infrared radiations (reduce the temperature inside greenhouse)
3. Reduce the amount of pests inside the greenhouse
4. More light diffusion in the greenhouse
5. Better crop quality in term of size, shape, color, and taste
Sunlight contains various rays such as white light, Infrared rays, Ultraviolet rays but not everyone knows that most of photosynthesize happen by stimulate just some
wavelength that human eyes could see.
The white light is around 400-700 nanometer while the plant could absorb better light at two different wavelengths. First, at 400-500 nanometer that includes purple, blue, green, second, red light at 600-700 nanometer. Red is the color that plant could absorb the most and has an influence to bloom. However, each plant has a different response to the different wavelength.
The overheating problem in greenhouse could be found in many areas in Thailand and many countries worldwide due to the global warming. The temperature could go up to 50 degree Celsius in the summer time which cause damage to the crops.
VSC cooling diffused film is our new product of the agricultural line and many users are very satisfied with the testing results. It is significantly decreasing the temperature inside greenhouse compare with standard film by 3-5 degree Celsius or some areas could decrease up to 7 degree Celsius (test results in 2019, Thailand). Other benefits are better crop yields in term of quantity and quality, protect from the burning leaves, and gain earlier crop yields.

VSC has had the chance to work with The Royal Project Foundation which is an initiative of His Majesty,
King Bhumibol Adulyadej of Thailand. The main purpose of this project is to solve the problems of
deforestation, poverty, and opium production by promoting the alternative crops. In order to improve
the quality of agricultural production, the project also invests in research and development of
agriculture film which are provided by VSC. We are proud to be part of this successful project to
provide the best outcome in crops growing for the farmers in the Northern provinces in Thailand.
