The method of improving the surface performance of PET film. Source: Protective film factory direct sales. Release time: 2019-03-17 Click: 2406 In order to improve the surface performance of PET film to improve the adaptability of printing and the bonding force of the vacuum aluminized layer, corona is usually used. Treatment method to increase the surface tension of the film. However, the corona method has problems such as timeliness, especially in a high temperature and high humidity environment, the tension of the film 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. Foshan Polyva has developed a series of PET chemical coating products: such as coating with water-soluble polymers, can increase the surface tension of PET film; coating with acrylic emulsion can improve the adaptability of printing (water-soluble inks can be used); Coating with polyurethane aqueous solution can strengthen the bonding force between the aluminized layer and the PET base film and increase the thickness of the aluminized layer. In addition, the coating method can also be used to produce high-barrier films and antistatic films. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fireproof) PET film, inkjet printing film , Antistatic PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
