Methods for Repairing PO Films
The coated PO film is made by removing components such as anti - fogging agents and anti - dripping agents from the functional masterbatch during the processing, and after blow molding, through a coating process, applying a coating liquid with anti - fogging and anti - dripping functions onto a very thin and uniform base film, and then drying and curing it. PO film has the characteristics of high strength, good anti - aging performance, high light transmittance, and low functional decay rate, and can be used continuously for 5 to 6 years. The old film is easy to handle, can be used as a renewable resource, and will not emit harmful gases when incinerated. PO film has been produced and promoted in Japan. In recent years, some domestic manufacturers have produced and sold it, but it has not been widely promoted and applied. PO film is a kind of agricultural film often used in the agricultural industry. It is very popular among consumers because of its good light transmittance and strong heat - insulation performance. However, PO film will inevitably be damaged during use. So, how should we repair the PO film when this problem occurs?
