Protective film material:

PP Material

PP material protective film is the first appeared on the market, the chemical name is polypropylene, without any adsorption capacity, generally used glue to stick, tear off the screen will leave a glue mark, will corrode the screen for a long time. Now this material has been basically eliminated by the majority of protective film manufacturers, but some roadside stalls are still selling, you should pay attention to!

PVC Material

PVC material protection paste is characterized by its soft texture and easy pasting, but this material is thicker, poor transmittance, making the screen look hazy. After tearing it off, it will leave a glue mark on the screen. This material is also easier to turn butter with the change of temperature, and has a shorter service life. So there is no such protective film on the market now. At present, the market can see an improved version of the protective film of PVC, which solves the problems of the previous thickness and poor light transmittance, but still can not solve the problem of easy turning butter out, and it should be noted that the material of PVC does not have scratch resistance, and after a period of time, there will be obvious scratches on the protective film. In addition, PVC itself is a toxic material, containing heavy metals, which has been completely discontinued in Europe. This kind of improved PVC screen protector is widely sold in the market, characterized by the soft feeling in hand and the low price. The price is generally around 10 yuan, some miscellaneous brands even 5 yuan also have transactions, many well-known protective film manufacturers have stopped using this material.

PET Material

PET protective film is the most common protective paste on the market at present. In fact, the plastic cola bottle we usually see is made of PET, also known as Bout bottle. Chemical name is polyester film. The characteristics of the protective film made of PET are hard and scratch-resistant. And it will not turn yellow like the PVC material for a long time. Oil. But generally, the protective film of PET depends on electrostatic adsorption. It is easy to foam and fall off, but it can be reused even if it is washed in clean water. The price of protective film made of PET is much higher than that of PVC. When many foreign well-known brands of mobile phones leave the factory, they are randomly equipped with PET material protection stickers, which are exquisite in workmanship and packaging. There are protective stickers specially made for hot-purchased mobile phone models. They can be directly used without cutting. The famous brands in the market, REDBOBO brand stickers and OK8 mobile phone stickers, are used as protective stickers. Some products are also made of PET material.

AR Material

AR material protection paste is the best screen protection paste on the market at present. AR is a synthetic material, generally divided into three layers, silica gel as the adsorption layer, PET as the intermediate layer, outer layer as the special treatment layer. Special treatment layer is generally divided into two kinds, AG treatment layer and HC treatment layer, AG is anti-glare treatment, abrasive protection film is used in this way. HC is hardness treatment, is a high-transparency protection film. This kind of screen protection film is characterized by non-reflective screen, high transmittance (more than 95%) and will not affect the display effect of the screen. And the material surface is soft and has strong anti-friction and anti-scratch ability after special processing. It will not scratch after long time use. The chemical material silica gel is adsorbed on the screen of mobile phone, so it will not hurt the screen itself and leave no mark after tearing off. It can also be cleaned. It is now the main research and development target of well-known protective film manufacturers such as OK8, BENKS and so on. At present, it can be easily bought on the market, and the price is more expensive than that of PET material.

PE Material

The main raw material is LLDPE. The material is soft and has certain stretchability. Generally, the thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G according to the requirements of use (viscosities are differentiated between domestic and foreign, for example, 200 grams of Korean membrane is equivalent to about 80 grams of domestic membrane). PE material protective film projects are divided into electrostatic film, reticulated film and so on. Electrostatic film, as its name implies, is a protective film with no glue at all. Of course, it is relatively weak and mainly used for surface protection such as electroplating. Reticulated film is a kind of protective film with many grids on the surface. This protective film has good air permeability and beautiful pasting effect, unlike plain film, it will leave bubbles.

OPP Material

OPP protective film is similar to PET protective film in appearance. Its hardness is higher and it has certain flame retardancy, but its pasting effect is poor, and it is seldom used in the general market.
