At this stage, when people are doing plastic film vegetable greenhouses, they often encounter the problem of selection of shed film, and the main use film of mainstream products on the market for many years is divided into po film and pe film, so today's web knitting according to its own work experience to master the way to share the shed film selection, if there are doubts can be corrected.

For the agricultural producers of sunlight greenhouses in North China, the preferred is po film. Due to the rapid heating in the morning, people's silk wadded quilt will be put down at noon with thermal insulation and insulation effect, so the heat generated will not be harmed by the poor thermal insulation and insulation ability of the shed film. In addition, the temperature difference between the inside and outside of the shed in North China is large, so it is necessary to have dripping fog elimination.

In eastern China, smart greenhouses are all used, so pe film can be selected, pe film insulation performance is good at night, in addition to coastal areas, the temperature difference between inside and outside the shed is small, less fog water.

po film is a new type of agricultural film that uses the raw materials of advanced olefin and other modifiers, and uses the air drying process of external spray paint to produce a high yield. It has very good transparency, low light transmittance and high transparency. So early morning txt line penetration rate is high, transmittance is low, so it will raise temperature quickly in the morning. In addition, this kind of agricultural film also has strong tensile strength and tear and compressive strength. PE film is often said to be polyethylene film, high pressure polyethylene plastic film transparency and sealing, waterproof, waterproof.

In addition, this kind of agricultural film also has strong tensile strength and tear and compressive strength. PE film is that people often say polyethylene film, PE film permeability is very large. The high pressure polyethylene plastic film has strong transparency and sealing, and can be waterproof and waterproof. The performance of the two films is different from the overall point of view. The characteristics of po film have slightly advantages compared with PE film, and the actual effect is stronger.
