How to improve the surface properties of PET films


In order to improve the surface properties of PET film, improve the printing adaptability and the bonding force of vacuum aluminum coating, corona treatment is usually used to improve the surface tension of the film.However, the corona method has some problems such as timeliness, especially in the environment of high temperature and high humidity, the film tension after corona treatment is easily attenuated.However, chemical coating law does not exist such a problem, so by the printing industry and aluminum plating favored.Some domestic enterprises have developed PET chemical coating series products: coating with water-soluble polymer can improve the surface tension of PET film;Coated with acrylate emulsion to improve the adaptability of printing (water-soluble ink can be used);Polyurethane aqueous solution coating can strengthen the bonding force of aluminized coating and PET base film, and increase the thickness of aluminized coating.In addition, the coating method can also be used to produce high barrier film and antistatic film.
