In the wholesale process of polymer protective film, quality is a critical factor, so learning to identify protective film is a very important method. There are generally two types of protective film, one is water glue with release paper, and the other is oil glue without release paper. For the oil-glue composite film, it is generally not called a protective film because of its different uses. It is mainly used in advertising production, such as computer engraving. The function of the oil-glue is that the engraved characters and patterns are not easily deformed and are suitable for long-term Paste, not easy to warp and fall off. As for the water-glue composite protective film, it is mainly used for carving art glass, as well as the surface protection of other objects. The above two methods are the methods to identify the polymer protective film. I hope everyone can master it after reading it. After all, this is related to the quality of our use. Next: What are the reasons for the rainbow pattern of the protective film? Previous: What are the factors that affect the quality of the polymer protective film
