Effect of pet protective film Properties of PET protective film

The pet protective film is divided into application areas in the following areas: surface of metal products, surface of coated metal products, surface of plastic products, surface of automotive products, surface of electronic products, surface of label products, surface of profile products, and other product surfaces. Next Xiaobian introduced the role of pet protective film and the characteristics of PET protective film.

The role of pet protective film

The PET protective film material is transparent and colorless, and the surface has been hardened. Generally, the hardened surface of the PET protective film material is between 3H and 4H depending on the place of production. The better the surface hardening, the stronger the abrasion resistance. Transmittance is also the main property of PET protective film material. Generally, light transmittance is above 90%. Higher light transmittance not only makes us have a good visual effect when using related instruments, but also has a good eye Protection.

Currently on the market, Japan's PET protective film material is relatively good, followed by Taiwan, South Korea once again because of the PET material has a light weight, high strength, transparency and good gas barrier, non-toxic, tasteless, etc., to obtain rapid development. Since the 1990s, the production and application of plastic packaging materials have mushroomed. Then, with the maturation of touch technology, PET materials will naturally be used on a variety of LCD screens, namely today's PET protective film PET. The protective film mainly has high transparency, matte, diamond, anti-peep, radiation protection, anti-fingerprint, mirror and other functional properties. It is reported that now is developing a 3D naked eye protective film material, mainly to see 3D movies with 3D effects.

PET protective film characteristics

1. Non-toxic, non-hazardous, reliable sanitary performance, can be used for the packaging of food, medicine and medical equipment, and can disinfect the packaged articles. It can be recycled and used. When it is burned, it will not produce harmful substances that will harm the environment.

2. The protective film is coated with polymer conductive polymer, with low surface resistivity, stable performance, good chemical resistance, and resistance to chemical substances. It is not affected by the environment such as air, so PET protective film is suitable for packaging materials and has better barrier properties against oxygen and water vapor. Excellent thermoforming performance, comparable to PVC sheet, can be used for vacuum molding and excellent PET thermoforming products.

3, PET material protective film has excellent transparency and finish, surface decoration performance is excellent, can be without surface treatment, can be printed, easily pressed into a pattern.

Common Quality Problems of PET Protective Film Materials

Rainbow grain is a problem that PET protective film material often encounters now, because the surface of PET protective film material needs to be hardened. Hardening is done through high temperature treatment, so a colored stripe is formed on the surface of the material.

The crystal point is also a common quality problem for PET protective film materials. The crystal point refers to those small pits on the surface of the protective film material, and is also known as a bright spot. It is mainly found in three-layer PET protective film materials. The main reason is due to the use of silica gel synthesis. Silica gel has fluidity. If the surface of the protective film material encounters the squeezing of some small particles, it will form a crystal point, avoiding the crystal point. The best way is to protect the surface of the protective film!

Editor's summary: The role of the pet protective film and the properties of the PET protective film are introduced here, and I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
