PET protective film is the most common protective film on the market. The characteristics of PET protective film are: 1. It has excellent transparency and smoothness, and the display effect is very good. 2. No DU, hygienic. 3. Good thermoforming performance, which is equivalent to ordinary PVC sheet, and can be made into PET thermoforming products with excellent performance by vacuum forming. PET sheet is considered to be an ideal packaging material that meets the requirements of environmental protection. 4. Excellent surface decoration performance, can be printed without surface treatment, easy to emboss patterns, easy to metallize (vacuum metallization). 5. Coated with high molecular conductive polymer, with low surface resistivity and stable performance, it will not be affected by ambient temperature and humidity. 6. Have good mechanical strength. 7. Good chemical resistance, can withstand the erosion of various chemical substances. 8. It has good adaptability to environmental protection, can be recycled economically and conveniently, and does not produce harmful substances that affect the environment when incinerating its waste. 9. Good barrier properties to oxygen and water vapor.
The main uses of PET protective film: 1. Surface hardening (HC) treatment up to 3.5-4H, anti-scratch and wear-resistant. 2. The silicone composite layer is an adhesive, which can avoid the formation of air bubbles. 3. The characteristics of silica gel are that it can be pasted repeatedly without leaving any traces or corroding the surface. 4. It is used to protect LCD, touch screen, mobile phone, digital camera and PDA screen, avoid scratches during use, and achieve the effect of protecting the screen. 5. It is composed of optical grade transparent polyester film (PET) coated with silicone, and then pasted with transparent polyester (PET) release film. 6. The composite silicone layer can effectively absorb some direct collisions and protect the display screen from damage. 7. The optical effect of ultra-high light transmittance, and there is no glue residue after removal. 8. Non-reflective, increase the color of the display. 9. Silica gel will not deteriorate over time, and will not leave corrosive adhesives on the screen surface like other pastes, which is safe and reliable.
