Introduction

In order to improve the surface properties of the PET sheet, thereby improving the adaptability of printing and the bonding force of the vacuum aluminized layer, corona treatment is usually used to increase the surface tension of the sheet. However, the corona method has problems such as timeliness, especially in a high temperature and high humidity environment, the tension of the PET sheet after the corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing industry and the aluminum plating industry. In addition, the coating method can also be used to produce high barrier and antistatic sheets.
