The production process of PET polyester film will give you a detailed explanation: Surface treatment: In order to improve the hygroscopicity of our polyester film, the surface treatment process is carried out. There are two types of this treatment: 1. Etching is a treatment with trichloroacetic acid (TCA) to change the molecular structure of the film surface. This treatment method is to adapt the film to water-dispersed coating, otherwise it will not adhere to the untreated PET surface. 2. The chemical treatment method refers to the establishment of a 'bridge' between the polyester film and the subsequent coating layer.
