The nature of PET protective film material-film supplier

The development of PET protective film materials. PET materials were developed by American companies and Japanese companies in the early 1970s and began to be mainly used in industry. For example, the Coca-Cola plastic bottles we see today are PET materials. PET material has the advantages of light weight, super strength, good transparency and gas barrier, non-toxicity, and odorless, and has gained a rapid development trend. Since the 1990s, the production and application of plastic packaging materials have developed like bamboo shoots after a rain. With the maturity of contact technology, PET materials have also been reasonably used in liquid crystal displays, which are today's PET protective films. The chemical structure of PET protective film material: PET is polyethylene terephthalate in the whole process, which is made by the condensation polymerization of terephthalic acid and ethylene glycol. The nature of the PET protective film material, the PET protective film material is transparent and colorless, and the surface is hardened. General PET protective film materials have a surface hardening value between 3H-4H depending on the place of production. The better the surface hardening, the stronger the abrasion resistance. Light transmittance is also the main property of PET protective film materials. Generally, the light transmittance is above 90% and the light transmittance is high. It not only has a good visual effect when we use related instruments, but also has a good protective film effect on the eyes. Now, in the market, Japan's PET protective film materials are relatively excellent, followed by Taiwan, and South Korea is once again excellent. Types of PET protective film materials, such as high permeability, frosted, diamond, anti-peep, anti-radiation, anti-fingerprint, mirror and other PET protective film materials. Now we have developed a 3D naked eye protective film material. It is said that there is a 3D effect when watching 3D movies. Common quality problems of PET protective film materials: iris is the current problem faced by PET protective film materials, and the surface of the PET protective film material has been hardened. The hardening process is high temperature, so the crystal dots that form color stripes on the surface of the material are also common quality problems of PET protective film materials. The crystal dots refer to the small holes on the surface of the protective film material, which are also called bright spots. This is mainly seen in the three-layer PET protective film material. The main reason is that it is synthesized with silica gel, which has fluidity. The surface of the protective film material is compressed by small particles to form crystal points. The best way to avoid the crystal points is to protect the surface of the protective film. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
