What Material Is The Protective Film Made Of?
- Jan 23, 2019 -

Customers often ask when choosing protective film, which material is used to make this protective film, and the material of each protective film is different, and its product composition, performance and application fields are different, so these protective film products will be asked before purchasing, below to tell you "what material is used to make protective film".

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.

PP material

PP material protective film appeared on the market early, this material is actually the material of plastic bags we usually use, chemical name is polypropylene, there is no adsorption capacity, generally with 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, we should pay attention to!

PVC material

PVC material protection paste is characterized by its soft texture, and easy to paste, but this material is thicker, poor transmittance, so that the screen looks hazy. It will also 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 previous problems of poor thickness and light transmittance, but still can not solve the problem of easy turning butter, and it should be noted that the material of PVC does not have the ability to resist scratch. After a period of time, there will be obvious scratches on the protective film, which will affect the display effect of the screen and also affect the overall mobile phone. In addition, PVC itself is a toxic material, containing heavy metals, which has been completely discontinued in Europe. This modified version of PVC screen protective film is widely sold on the market, characterized by the soft feeling in hand and the low price. The price is generally around 10 yuan, some miscellaneous brands and even 5 yuan are also traded, and many well-known protective film manufacturers have already. Stop using this material.

PET material

PET protective film is a common protective paste on the market at present. In fact, the plastic cola bottle we usually see is made of PET, also known as Bott bottle. The chemical name of the protective film is polyester film. The characteristics of the protective film made of PET are hard and scratch-resistant. And it will not turn butter like the PVC material for a long time. But generally, PET protective film depends on electrostatic adsorption, which is easy to foam and fall off, but it can be reused even if it falls off and washed in clean water. The price of PET protective film 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. Some products of famous brands REDBOBO and OK8 mobile phone stickers on the market are also made of PET material.

AR material

AR material protection paste is a good 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 treatment is anti-glare treatment, abrasive protection film is the use of this treatment. HC is hardness treatment, is the treatment method used for high-transparency protection film. Screen does not reflect light, high transmittance (more than 95%) will not affect the display effect of the screen. Moreover, the surface of the material is treated by special technology, which has soft texture, strong anti-friction and anti-scratch ability, and will not scratch for a long time. The chemical material silica gel is adsorbed on the screen of the mobile phone, so it will not cause damage to the screen itself, and will not leave a mark after tearing off. It can also be washed and reused. It is a well-known protective film manufacturer such as O. K8, BENKS and other major research and development objects. At present, it can be easily bought on the market, and the price is more expensive than that of PET material.

OPP material

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

Summary: Understanding what materials are used to make protective film products and the application fields of related products will help us find protective film suitable for our use more quickly.
