How to choose greenhouse film, which is better, PO film or PE film?

There are a lot of agricultural films on the market, which may confuse everyone, so plastics will introduce the main PO films and PE films on the market. 1. Introduction of PO film and PE film PO film: is a new type of agricultural film produced by spraying and drying with high-grade olefin raw materials and other additives. It has super tensile strength and tear resistance. PE film: It is the polyethylene film we often say, with good transparency and heat-sealability, waterproof and moisture-proof. Difference: Compared with PE film, PO film has better light transmittance and stronger ability to absorb temperature. The light transmittance of the greenhouse is 4.5 to 4.7 percentage points higher than that of the PE film, and the daily average temperature of the greenhouse is also about 1°C higher than that of the PE film. 2. How to choose PO film and PE film 1. According to the performance, choose the large temperature difference between the inside and outside of the northern area. You should choose the PO film with strong anti-fogging and dripping, so that the temperature rises quickly in the morning, and it will work well when you put the quilt in the afternoon. Thermal insulation effect. In southern areas, greenhouses need better heat preservation at night. You can choose PE film or PE film for night heat preservation. At the same time, the temperature difference between inside and outside of the greenhouse is small, and there will be less fog. 2. According to the price, PE film is cheaper than PO film. For general growers, PE film is sufficient for growing vegetables. 3. PO film with different service life uses high-tech antioxidants and light stabilizers to extend the service life of the agricultural film. Normal use can reach more than 3 years. The PO film can be used for six months to one year under the conditions of sun exposure. You can choose the shed film according to your actual situation. That's all for today's sharing. I wish you all a good journey in planting, and the crops will be harvested and profitable!
