Surface treatment of PET polyester film: The purpose of polymer surface modification is to change the appearance, supramolecular structure, defect or stress state of the polymer surface by means of physical or chemical methods without affecting the bulk properties. Chemical composition, etc., to remove dirt, increase the surface area, and remove the weak boundary layer, thereby improving the mechanical, chemical, mechanical, optical, electrical and other properties of the polymer surface, enhancing the function of the polymer, and expanding their application areas; PET polyester film surface The tension is low, the affinity to the coating liquid is small, and the PET polyester film has high crystallinity. After the coating liquid is applied, it is not easy to be swollen by the coating liquid to cause intermolecular diffusion, so the adhesion is relatively poor. Therefore, treating the surface of the PET film substrate can increase its surface tension, reduce its surface crystallinity, and improve its surface adhesion. 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. Interested parties welcome to inquire!
