The main raw material of the protective film is LDPE, which is soft in material and has certain stretchability. Generally, the thickness is 0.05MM-0.15MM, and the viscosity varies from 5G to 500G depending on the use requirements (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 protective film for PE material is divided into an electrostatic protective film and a textured protective film. The electrostatic protective film is a kind of protective film with electrostatic adsorption force. It is a kind of protective film with no glue at all. Of course, the viscosity is relatively weak, and it is mainly used for surface protection such as electroplating. The textured protective film is a kind of protective film with many meshes on the surface. This protective film has better air permeability and the paste effect is more beautiful, unlike the plain film which will leave bubbles.
The protective film of OPP material is closer to the PET protective film in appearance, and has a relatively high hardness and a certain flame retardancy, but the effect of sticking is poor, and it is rarely used in the market.
Many users of protective films have some doubts about the anti-fingerprint mobile phone protective film. Can the anti-fingerprint mobile phone protective film really prevent fingerprints? How is it prevented?
In fact, the principle of anti-fingerprint mobile phone screen film design is to decentralize the texture of the fingerprint. When the finger touches the LCD screen of the general mobile phone, it is easy to see the clear fingerprint texture. In order to achieve the ideal anti-fingerprint effect, those defenses The protective film of the fingerprint mobile phone is made of special materials and special techniques, and the fingerprint of the finger is dispersed as much as possible to realize the so-called anti-fingerprint, so that the fingerprint of the mobile phone screen cannot be displayed on the mobile phone, and the user cannot see it with the naked eye. Fingerprints, even those seen with high-power microscopes, are difficult to distinguish and play a role in antibacterial.
