Nowadays, po film has become more and more greenhouse vegetable covering film products, a good product can not only accelerate the effect of everyone's agriculture, so that vegetables and fruits, fresh fruits as soon as possible to improve; In the case of bad weather, it can also have a very good maintenance effect on vegetables and fruits, fruits and vegetables. Therefore, it is very important to choose a good product, so what should we pay attention to when dealing with various po films on the sales market?

1. A significant characteristic of the membrane is light transmission, light has a particularly important effect on the plant photosynthesis of green plants, so the antifouling is an index value of discrimination. The general plastic greenhouse film on the market can absorb dust, and the dust will accumulate in the greenhouse film for a little longer, which will reduce the transmittance of the film. The cost-effective PO film outer layer coating can block the absorption of dust, and it is not easy to settle in the greenhouse film, and further improve the light transmission of the greenhouse film, if the rain after precipitation erosion, the plastic film will be like new.

2. The anti-aging property of the film immediately determines the length of the use time of the Po film. In general, the use period of the poor quality po film is about one year, and the anti-aging time of the cost-effective PO film is 3 to 4 years. In that way, it saves the time to remove and replace the plastic film, and it is also convenient for farmers.

3. The longer the time of defogging indicates that the characteristics of this film are better, and the internal coating of the cost-effective po film is not thin film, but granular. The general anti-fog flow of plastic film is in 4 to 6 months, and some products are one year. The particle coated po film can guarantee the infinite increase of the drip-free period of the anti-fog mirror.
