Corona treatment method to increase the surface tension of the film-film supplier

by:POLYVA     2022-01-29
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, corona treatment is usually used 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. Dongguan Wantai has developed a series of PET chemical coating products: such as coating with water-soluble polymer, can increase the surface tension of PET film; coating with acrylic emulsion can improve the adaptability of printing (water-soluble ink 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. Is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
