Factors Affecting the Appearance Quality of PET Release Film (1)-Film Supplier
When choosing PET release film, the appearance of the product has always been valued by many buyers. However, there are many reasons why the appearance of the product is unsatisfactory, so the coating online will take everyone to see what factors affect the appearance quality of the PET release film? Rainbow pattern-the key first step The release film and rainbow pattern are originally unrelated, but since the silicon on, the two are inseparable, so whether there is rainbow pattern, it becomes the investigation of the release film The critical first step. The main reason for the formation of the rainbow pattern is the solvent. In the production process, in order to reduce the coating amount as much as possible, it is necessary to add more solvent oil. The direct result is that there is more solvent oil on the release paper than silicone oil. During the thermal drying process, the solvent oil evaporates, leaving a rainbow pattern. According to Coating Online, if you need to laminate high-viscosity tapes such as 3M TESA, or when you want to punch a small shape, you must choose the appropriate release paper. Because the shape of the punching material is very small, a very light release force is required, but if the release force is too light, it will fly off during the punching process and the position will change. The high-end industrial tapes we use every day basically use oil glue, so the release film is very demanding. Whether there is rainbow pattern or not directly affects the applicability of the tape.
