2. The characteristic of PVC material protection sticker is that it has a soft texture and is easy to stick, but this material is relatively thick and has poor light transmittance, which makes the screen look dim. It will also leave a glue mark on the screen after tearing it off. This kind of material is also easier to turn yellow and oil out as the temperature changes, and the service life is relatively short.

3. The improved PVC protective film solves the previous problems of heavy weight and poor light transmittance.

4. The PET protective film is the most common type of protective sticker on the market. This three-layer PET protective film is used for mobile phones and tablet computers.
