Introduction of PET single sided hardened film

Pet single-side and double-side hardening film is surface hardening treatment on PET film. The film has good adhesion to ink and printing effect. The following is Zhejiang Kaixin Photoelectric Technology Co., Ltd. for you to introduce in detail the functional parameters of PET single-sided and double-sided hardening film and its use.

The material is widely used in mobile phone screen, touch screen, liquid crystal display, instrument panel, control panel, film switch panel, LCD board, LED, DVD screen protection, flat panel display surface protection, household appliances. Mold shell is machined with mold casting.

Introduction of PET single sided hardened film

In order to improve the surface properties of PET film, improve the adaptability of printing and the adhesion of vacuum aluminum plating, corona treatment is usually used to improve the surface tension of PET film. However, the corona method has some problems such as timeliness, especially in high temperature and humidity environment, the film tension after corona treatment is easy to decay. However, there is no such problem in the law of chemical coating, so it is favored by the printing industry and the aluminum plating industry.

Introduction of PET single sided hardened film

PET chemical coating products have been developed in the industry: coating with water-soluble polymers can improve the surface tension of PET hardened film; coating with acrylic emulsion can improve printing adaptability (water-soluble ink) can be used; coating with polyurethane aqueous solution can enhance the adhesion between aluminized layer and PET substrate and increase the adhesion. Thickness of aluminized layer. In addition, high resistance diaphragm and antistatic film can be made by coating method.
