Chemical coating of PET film-technical knowledge
The source of the chemical coating effect of the PET film: direct sales from the protective film factory Release time: 2019-09-27 Click: 1043 In order to improve the surface properties of the PET film, to improve the adaptability of printing and the bonding force of the vacuum aluminized layer, electricity is usually used Halo 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. Domestic companies have developed a series of PET chemical coating products: such as coating with water-soluble polymers, can increase the surface tension of the 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. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with multiple functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing Film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, optical PET film, etc. Interested parties welcome to inquire!
