Not all PO films, they are called Mingjinghua.

The day before, the 16th China Greenhouse Industry Conference and 2017 Asian Horticultural Exposition came to an end. As the souvenir sponsor of the conference and the main exhibitors of the Expo, I would like to be impressed by the small partners.




Above is the souvenir we provide for the annual meeting of the greenhouse - the plant grows light, beautiful and practical.



The listeners under the stands raised their mobile phones to take pictures, and they knew how good our boss’s speech was, how good the dry goods were!



Not only the annual greenhouse meeting, but also the horticultural exposition.



Explain the principle of using PO film for French friends.



The boss is stunned.


Why are their eyes so attracted? ? ?

Only because of the industry-leading products - Mingjinghua PO film



Mingjinghua PO coating film is a brand-new cover specially developed by Sumitomo Chemical Co., Ltd., which is specially researched and produced by Sumitomo Chemical Co., Ltd. for the low transmittance of the existing greenhouse greenhouse film, short life of the antifogging function, and easy to be affected by dust. membrane. It has three innovative technologies:


1, continuous high light transmission: the use of nano-coating self-cleaning technology on the outer layer, refused to adhere to dust, often used. The initial light transmittance is 93% (10 filaments), and the degree of attenuation of light transmittance is very low even in contaminated areas.


2, long-lasting anti-fog technology: anti-fog and anti-flow function and the same life of the membrane.


3, artificial environmental degradation: Sumitomo's own unique raw materials will not produce toxic gases when artificially degraded, completely environmentally friendly.


There are also several improvements


1. Long service life: PO membrane adopts Sumitomo Chemical's own unique antioxidant and light stabilizer, anti-aging, weather resistance, corrosion resistance, high temperature, 15 wire use and functional life can reach 4-5 years.


2. High tensile strength and tear strength: The PO film of Minghua 10 silk can reach the strength of 15 PE or EVA film in China.


3, superior insulation performance: PO film uses polyolefin raw materials, low haze, high transparency. In the morning, the light transmittance is high, the scattering rate is low, and the morning temperature rises rapidly. The inner layer of the film is made of special organic heat preservation agent, so that most of the infrared radiation radiated from the shed is reflected back, which effectively controls the heat dissipation, ensures the nighttime growth temperature of the crop, and effectively prevents freezing damage to the crop caused by nighttime temperature drop.


4, reduce pests and diseases: PO film transmittance is high, unique anti-fog technology allows the sun to quickly enter the shed, warming fast, relative humidity is reduced, pests and diseases are reduced. At the same time, the ultraviolet light is transmitted more, the sterilization performance is good, and the number of medications can be reduced by more than 30%. 5, high yield and high quality: due to the high light transmittance of the film, photosynthesis is strong, the temperature is high, the yield can be increased by 10-25%. The crop grows fast and can take the lead in the morning market. The fruits of the crops are brightly colored, uniform, and the quality is superior.



Principle of dripping and fog elimination


No damage without comparison



Why is PO film a trend?

  • Land policy: Because of the nature of land management, the Beijing-Tianjin region, the Yangtze River Delta region, and the Pearl River Delta region have strict restrictions on the amount of agricultural land used, the width of road parks, and the curing of greenhouses. This limits the need for large-scale glass greenhouses. The development of these areas has also gradually eliminated subsidies for glass greenhouses, such as the Shanghai area. However, a glass greenhouse is determined to be suitable for the cultivation needs of some varieties. The government and the growers are looking for some balance points. Many of the greenhouse structures have been used, but the coverage is changed to F-CLEAN or PO membranes and other soft membranes. In the greenhouse, the amount of sputum was reduced, but there was no reduction in light transmittance safety and climate control. The government has also begun to subsidize such greenhouses.


  • The practicality and extensiveness of the membrane greenhouse: the membrane greenhouse is increasing every year, the proportion of PO membranes is increasing geometrically, and the membrane greenhouse has very low structural requirements, and the subsequent maintenance is relatively simple, and is suitable for various fields. Planting and cultivation, the solar greenhouse in the north, the single arch shed south of the Yellow River almost occupies more than half of the facilities and agriculture, and the greenhouse of the diaphragm has also increased steadily, and the government support is growing. There are more and more projects for large-scale intensive mechanization. For example, projects in Yunnan, Ningxia, Shandong and other places with more than 40 hectares have emerged, and there will be a volume increase in the next five years.


  • Growers' quality awareness: The technical level of growers is getting higher and higher, and the quality of greenhouses is getting higher and higher. They are not simply satisfied with just building the greenhouse, but also considering suitability, initial investment and operation. Cost balance For some government projects, growers are increasingly involved in design decisions. They are more aware of their needs. In the past, users did not have decision-making power, and the decision-makers did not understand the greenhouse situation is gradually improving.


  • PO film has advantages over other products: high light transmittance, defogging droplets, environmentally friendly degradation, etc., many of which are not available in other similar products.
