What are the materials of mobile phone protective film, why is the film so expensive, China protecti

The main thing is that the artificial film = 80% labor + 20% material.

There are four main materials for mobile phone films: PP material, PVC material, PET material, and ARM material.

The PP material film is relatively soft, and the light transmittance is also very poor, which can not play the role of anti-scratch and anti-wear, and can only be dust-proof.

PVC material film is relatively soft and easy to paste, but it is relatively thick, and the light transmittance is not very good. And if you tear off the film, it will leave residual glue on the mobile phone screen, which will affect the appearance.

The PET film has high light transmittance, and there is no residual glue after tearing off, and it is not easy to appear small bubbles in the middle of the film. However, the high reflectivity of this film will cause users to not be able to see the words on the screen clearly, and it is easy to leave traces such as fingerprints on the surface.

ARM material, the membrane surface of this material has been treated with the latest technology, which has the ability to resist wear and scratch. At the same time, there are no bubbles after the product is pasted, and the light transmittance is also very good, and it will not leave any traces after tearing off. Relatively speaking, this kind of membrane has the best effect, ** is the most expensive.

Generally, mobile phone protective films include matte film, high permeability film, etc., and there are generally four types of PP material, PVC material, PET material, and ARM material.

The differences are: 1. Different functions, the original film of the mobile phone is to ensure that the screen of the mobile phone will not be scratched and dropped during the transportation and packaging process; The protective film is to protect the surface of the screen, prevent blue light, and prevent the screen from breaking when dropped.

2. The durability is different, the original film will lose its adhesion after long-term contact with air, and it is easy to curl and produce bubbles. The protective film generally has a long service life and basically does not fall off.

3. Different thicknesses. The original film is generally thinner than the protective film.

The differences are:

1. The functionality is different, the original film of the mobile phone is to ensure that the screen of the mobile phone will not be scratched in the process of leaving the factory to the packaging, and it will not be anti-falling; The protective film functionally protects the surface of the screen, prevents blue light, and prevents the screen from shattering when dropped.

2. The durability is different, the original film will lose its adhesion after a long time of contact with the air, and it is easy to warp and fall off to produce bubbles. The protective film generally has a long service life and basically does not warp and fall off.

3. The thickness is different. The original film is generally thinner than the protective film.

The main purpose is to ensure that the screen is not easy to shave in the process of leaving the factory to packaging, and this film will lose its adhesion after time of storage, so it cannot be used as a screen protector.

There is no original film for mobile phones, and the film that comes with it when you buy it is a packaging protective film, which cannot be used to make a screen protector, so you still have to buy another film, if you have a mobile phone film, ok8, Carden, Dooir, Banksy, Uobor and other brands are good.

It depends on what kind of protective film you choose. There are many varieties of protective film.

There is a difference between thickness and thinness, and the film between 5 and 20 yuan.

At present, there are many kinds of materials for protective film on the market, and the materials used in high, medium and low grades are different. Generally, the low-grade is made of PVC material, the definition of the protective film made of this material is not enough, with adhesive, it is not easy to take it after pasting it on the screen, even if it is taken off, there will be residual glue left on it, which is very difficult to deal with, and it is not recommended to use. The medium and high-grade protective film is made of PET material, and the PET material imported from Japan is better, and the protective film made has very high light transmittance and clarity, and has a certain thickness and hardness, which can play a role in anti-scratch and wear-resistant.

The materials of mobile phone protective film are as follows: PP material, PVC material, PET material, AR material, PE material, OPP material and other materials.

PP material does not have any adsorption capacity, generally glue to glue, after tearing off will leave a glue mark on the screen, will corrode the screen for a long time.

PVC material is soft in texture and easy to paste, but this material is thicker and has poor light transmittance, which makes the screen look hazy. Tearing off will also leave an imprint of glue on the screen. At the same time, this material is also relatively easy to turn yellow and oil with the change of temperature, and the service life is relatively short.

PET material is the most common protective film material on the market, which is relatively hard and scratch-resistant.

AR material is currently the best screen protector on the market. AR is a synthetic material, which is generally divided into three layers, silica gel is the adsorption layer, PET is the middle layer, and the outer layer is a special treatment layer. The special treatment layer is generally divided into two types, AG treatment layer and HC treatment layer, AG is anti-glare treatment, and the frosted protective film is treated in this way.

HC is a hardness treatment, which is a treatment used for highly transmittance protective films. This screen protector is characterized by its non-reflective screen and high light transmittance (more than 95%), which will not affect the display effect of the screen.

The raw material of PE material is LLDPE, which is relatively soft and has a certain stretch.

The mobile phone protective film made of OPP material is relatively close to the PET protective film from the appearance, its hardness is large, and it has a certain flame retardancy, but its paste use effect is poor, and it is rarely used in the general market.

There are PE, PET, OPP, PP, PVC and other protective films, but depending on which one you use, now the protective film of OCA glue is used more for mobile phones, and now the OCA protective film is a special protective film for Apple, so if you want a protective film, you can go to see OCA!
