Wholesale high transparent protective film, high transparent protective film, single layer protective film, punching protective film
PP protective film made of PP is the first to appear on the market. This material is actually the material of plastic bags that we usually use. The chemical name is polypropylene. It does not have any adsorption capacity. It is usually glued with glue. After tearing it off It will leave glue marks on the screen, which will corrode the screen over time. Now this material has been basically eliminated by the majority of protective film manufacturers, but some roadside stalls are still selling, everyone should pay attention! The characteristic of PVC material PVC protective film is that it has a soft texture and is easy to stick, but this material is more Thick, poor light transmittance, making the screen look dim. It will also leave glue marks on the screen after tearing it off. This kind of material is also easier to turn yellow and oil out with the change of temperature, and the service life is relatively short. So there is basically no such protective film on the market now. At present, what can be seen on the market is an improved version of PVC protective film, which solves the previous problems of heavy weight and poor light transmission, but still can’t solve the problem of easy turning yellow and oil, and it needs to pay attention to PVC. The material does not have the ability to resist scratches. Obvious scratches will appear on the protective film after a period of use, 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. PET material PET material protective film is currently the most common type of protective sticker on the market. In fact, the plastic cola bottles we usually see are made of PET material, also called PET bottles. The chemical name is polyester film. The PET protective film is characterized by its harder texture and scratch resistance. And after long-term use, it won't turn yellow and oil out like PVC materials. But the general PET protective film relies on electrostatic adsorption, which is easier to foam and fall off, but even if it falls off, it can be reused after washing it in clean water. The price of PET protective film is much more expensive than that of PVC. AR material screen protector. AR is a synthetic material, generally divided into three layers, silica gel is treated to absorb glare, and frosted protective film is used in this way. HC is hardness treatment, which is the treatment method used for high-transmittance protective film. This kind of screen protective film is characterized by the non-reflective screen, high light transmittance (above 95%), and will not affect the display effect of the screen. This kind of screen protective film is characterized by the non-reflective screen, high light transmittance (above 95%), and will not affect the display effect of the screen. Moreover, the surface of the material is treated with a special process, and its texture is soft, and it has strong anti-friction and anti-scratch ability. There will be no scratches even after long-term use. The adhesive is made of chemical silica gel which 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. And it can also be reused after cleaning, the PET is the middle layer, and the outer layer is the special treatment layer. The special treatment layer is generally divided into two types, the AG treatment layer and the HC treatment layer. AG is anti-glare treatment, and the frosted protective film adopts this treatment method. HC is hardness treatment, which is the treatment method used for high-transmittance protective film. OPP material OPP material protective film is relatively close to PET protective film in appearance, its hardness is relatively large, it has certain flame retardancy, but its sticking effect is poor. The main raw material of PE material is LLDPE, which is relatively soft and has certain properties. The stretchability. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G to 500G depending on the requirements of use (the viscosity is different between domestic and foreign countries, for example, 200 grams of Korean film is equivalent to about 80 grams in China). The PE material protective film project is also divided into electrostatic film, anilox film and so on. The electrostatic film, as its name implies, uses electrostatic adsorption as its adhesive force. It is a protective film with no glue at all. Of course, it is relatively weak and is mainly used for surface protection such as electroplating. Anilox film is a kind of protective film with many meshes on the surface. This kind of protective film has better air permeability and a more beautiful paste effect, unlike plain weave film that will leave air bubbles.
