There are many types of protective films on the market, which can be divided into the following types based on their materials. Generally, protective film manufacturers have them.
1. The protective film made of PP material was the earliest to appear on the market. Its chemical name is polypropylene, and it has no adsorption capacity. It is usually adhered with glue, and after tearing it off, it will leave a mark of glue on the screen, which will corrode the screen over time. It has been basically eliminated.
2. The characteristic of PVC protective stickers is that they have a soft texture and are easy to stick, but this material is relatively thick and has poor transparency, making the screen appear hazy. After tearing it off, it will also leave a mark of glue on the screen. This material is also relatively easy to turn yellow and produce oil with changes in temperature, resulting in a shorter service life.
3. The improved version of PVC protective film solves the problems of previous thickness and poor transparency.
4. PET protective film is the most common type of protective film on the market, and these three layers of PET protective film are used for mobile phones and tablets.
5. AR material protective stickers are the best known screen protective stickers on the market.
6. The main raw material of PE material is LLDPE, which is relatively soft and has a certain degree of stretchability.
7. The protective film made of OPP material is relatively similar to PET protective film in appearance, with high hardness and a certain degree of flame retardancy. However, its adhesive effect is poor, and it is rarely used in the general market.
8. The protective film made of OCA material is no different from other materials in appearance, but it is produced in Japan and is now widely used on Apple phones. It has better luminosity and hardness than other materials, so OCA is the most popular material for mobile phone protective films.
