PO is the common name of the English word polyolefin, Chinese refers to polyolefin, is a kind of butadiene, pe or advanced olefin polymer, po raw materials are widely used at this stage in the manufacture of plastic greenhouse film for agricultural vehicles, China's po membrane separation technology was introduced in Japan at the beginning. In China, from the introduction of po film production process, to the current stage of large-scale manufacturing of several agricultural film companies in China, it only took two years. Toda Plastic Industry is one of the large and medium-sized agricultural mulch companies that introduced Japan's po film production process earlier.

What kind of plastic film is po film? Compared with the general pe film, po film has many advantages, which is the reason for the rapid marketing and promotion of po film in China at this stage. The key is the following:

1) The clarity of po film is higher than that of pe film, which increases sunlight exposure, which is beneficial for crop growth and development.

2) The compressive strength of the po film is higher than that of the pe film, the compressive strength is that of the tensile strength, the tensile strength is strong, and it can resist hail and heavy snow and storms.

3)po film belongs to a kind of drip-free film, which also has the effect of defogging, and the period of validity of po film is lifetime. The general pe long-life drip film can only be valid for 3-4 months, and there is no fogging effect.

4) The thermal insulation properties of po film are better than those of pe film, which are beneficial to crop growth and development. It is very easy to freeze and crack crops at night when the temperature of the vault is low.

po film has so many advantages, why do some people say that po film is not good? Perhaps you will be buying a fake po film. po film is what plastic film, we have long been clear, but which plastic film is po film, there will be some people are not easy to distinguish. As a po film national industry standard revision enterprise, Dongda Plastic industry has been walking in the precedent of po film new product development. Here, people give us a detailed introduction to several types of ways to distinguish the advantages and disadvantages of po film:

1) The advantages and disadvantages of po film, depending on the validity period of drip defogging, the real good po film drip defogging period and the service life of plastic film are the same, in other words, the lifetime flow defogging, and the poor quality po film, the validity period of drip defogging is only valid for many months.

2) Look at the resulting contraction of water clarity. At this stage, the flow of po film fogging effect is maintained according to the addition of upstream drop fogging agent in the manufacturing, and there are two kinds of flow fogging agent at this stage, one is imported from Japan, and the other is domestic, the flow fogging agent imported from Japan is relatively stronger, and the price is much more expensive than the domestic one. Dongda Plastic industry is the choice of Japan imported drip antifogging agent, can produce mirror glass shrinkage water in the arch, very crystal clear, can penetrate a large number of sunlight sources.

3) Look at the thermal insulation and insulation characteristics of po film, how many degrees of thermal insulation and insulation of strong po film in the night temperature of the arch, accelerate the growth and development of crops at night, and sell in advance. If the po film with poor thermal insulation ability is applied, the growth and development rate of crops will be slow at night, and the crops will be late.

4) Look at the tensile strength of po film, good po film, can resist snow pressure and hail, the tensile strength of po film is related to the quality of metallocene materials.
