PP material protective film
The protective film made of PP material first appeared on the market, with the chemical name polypropylene. It has no adsorption ability and is usually glued together. After tearing off, it will leave adhesive marks on the screen, which will corrode the screen over time. It has been basically eliminated now.
PVC material protective film
The characteristic of 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 look hazy. Tearing it off will also leave adhesive marks on the screen. This material is also prone to yellowing and oiling with temperature changes, and has a shorter service life.
The improved version of PVC material protective film solves the problems of previous heaviness and poor transparency. However, the problem of easy yellowing and oil leakage has not been solved, and PVC material does not have scratch resistance. After a period of use, obvious scratches will appear on the protective film, which affects the display effect of the screen and the overall aesthetics of the phone. In addition, PVC itself is a toxic material containing heavy metal components, and its use has been completely stopped in Europe. This PVC modified version of the screen protector film is widely sold in the market, and it is cheap in price
PET material protective film
Protective film is the most common type of protective sticker on the market, and these three layers of PET protective film are used for mobile phones and tablets. The chemical name is polyester film. The characteristic is that the texture is relatively hard, scratch resistant, and will not turn yellow or oil like PVC material even after long-term use. However, the protective film of PET generally relies on electrostatic adsorption, which makes it easy to bubble and peel off. Even if it falls off, it can be reused after washing in clean water. The price of PET protective film is much higher than that of PVC. The use of PET material protective stickers has exquisite workmanship and packaging. There are protective stickers specially customized for popular mobile phone models, which can be used directly without cutting.
AR material protective film
Protective stickers are the best known screen protectors on the market. AR is a synthetic material that is generally divided into three layers: silicone as the adsorption layer, PET as the middle layer, and a special treatment layer on the outer layer The special treatment layer is generally divided into two types, AG treatment layer and HC treatment layer. AG is treated with anti glare, and the frosted protective film adopts this treatment method. HC is a hardness treatment method used for high transparency protective films The characteristic of this screen protector is that the screen does not reflect light, has high transparency (over 95%), and will not affect the display effect of the screen. The surface of the material has undergone special processing, and its texture is relatively soft, with strong resistance to friction and scratching Long term use will not cause scratches, and the adhesive is made of chemical material silicone that adheres to the phone screen, so it will not cause damage to the screen itself. After tearing it off, there will be no marks left, and it can also be cleaned and reused. The price is more expensive than PET material.
PE material protective film
The main raw material is LLDPE, which is relatively soft and has a certain degree of stretchability. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G depending on the usage requirements (the viscosity is divided differently in China and abroad, for example, 200 grams of Korean film is equivalent to about 80 grams in China). The protective film project of PE material includes electrostatic film, mesh film, etc. Electrostatic film is a protective film that uses electrostatic adsorption force as the adhesive force and has no glue at all. Of course, its adhesion is relatively weak and it is mainly used for surface protection such as electroplating. Mesh film is a type of protective film with many grids on the surface. This type of protective film has good breathability and a beautiful adhesive effect, unlike plain film which leaves bubbles.
OPP material protective film
OPP material protective film looks similar to PET protective film in appearance, with high hardness and certain flame retardancy. However, its adhesive effect is poor and it is rarely used in the general market.
OCA material protective film
The protective film of OCA material looks no different from other materials in appearance, but OCA material protective film is produced in Japan and is now most commonly used on Apple phones. Its brightness and hardness are better than other materials, so OCA is currently the most popular material for mobile phone protective film.PP material protective film
