There are various classifications of different materials for protective films. Below, we will mainly introduce some commonly used protective film materials.
PET material protective film is currently the most common type of protective tape on the market. In fact, the plastic cola bottles we usually see use PET material, also known as PET bottles. The chemical name is polyester film. The characteristic of PET material protective film is that the texture is relatively hard, it is more scratch resistant, and it will not turn yellow or oil like PVC material after long-term use. However, generally, PET protective film relies on electrostatic adsorption, which is easy to foam and fall off, However, even if it falls off and is washed in clean water, it can be reused. The price of PET protective film is much higher than that of PVC. Many well-known foreign brands of mobile phones are randomly equipped with PET material protective stickers when they leave the factory. The PET material protective stickers are exquisitely crafted and packaged, and there are protective stickers specifically tailored for popular phone models that can be used directly without cutting. Some well-known brands such as REDBOBO brand stickers and OK8 phone stickers on the market are also produced from PET material PE protective film
The main raw material is LLDPE, which is relatively soft and has a certain degree of stretchability. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G according to different usage requirements (in terms of viscosity, domestic and foreign classifications are different, such as 200 grams of Korean film equivalent to about 80 grams of domestic film). The protective film project of PE material includes electrostatic film, mesh film, etc. Electrostatic film, as the name suggests, is a protective film that uses electrostatic adsorption force as the adhesive force and is completely devoid of glue. Of course, the adhesive is relatively weak and mainly used for surface protection such as electroplating. Reticulated film is a type of protective film with many grids on the surface. This type of protective film has good breathability and beautiful adhesion effect, unlike flat film that leaves bubbles.
The protective film made of OPP material is relatively similar to PET protective film in appearance, with high hardness and a certain degree of flame retardancy. However, its adhesion and usage efficiency are poor, and it is rarely used in the general market.Phone Screen Protector,Screen Protectors,Hydrogel Film Sheets,Screen Protector Cutting Machines
