2: For white spots on the PE protective film, we need to use special adhesives. Here, we need to pay attention that the surface tension of the composite special adhesive is very low. Furthermore, our coating and spreading effect on the surface of the glue layer is much higher than that of the general-purpose adhesive. <br> <br>This also means that if we use glue glue, it will be easy to control the leveling of the glue liquid, so that a more ideal coating state can be achieved. In this way, from the adhesive coating state, we can avoid white spots on the PE protective film by using electronic glue. <br> <br>3: With regard to the white spots on the PE protective film, there is one more thing we may need to pay attention to, that is, there is a certain matching relationship between the viscosity of the glue and the number of wire rollers. In layman's terms, even if the matching range is too large, the coating state of the glue will be destroyed. In this case, the phenomenon of white spots of the PE protective film will appear.
