Suzhou PET protective film

Suzhou PET protective film material is transparent and colorless, the surface after the hardening process, according to the grace Jazz protective film Material Co., Ltd. to provide information on the general PET protective film material hardening values ??according to the origin of the different surfaces in between 3H-4H surface hardening the better, the stronger its wear resistance. The main properties of the light transmittance is PET protective film material, typically more than 90% transmittance, high light transmittance not only gives us a good good visual results when using the associated apparatus, but also to have a good eye The protective effect. PET protective membranes common quality problems: rainbow pattern problem PET protective film material are now often encountered, because PET protective film material surface to be hardened, hardening heat treatment is to go through, so it will form a section of the material surface colored stripes crystallization point PET protective film material is a common quality problems, crystal point is to protect the surface of the membrane material that pits pits, it was also known highlights. It is mainly on three common PET protective film material, the main causes is because the use of synthetic silica, silica gel, liquid, if the protective film surface encountered some small particles squeeze, it will form a crystal point, to avoid crystallization point The best way is to protect the surface of the protective film! Intelligent packaging materials. 4.0 With the advent of the industrial era, the development and application of intelligent packaging, food packaging will become the new trends, with a huge market potential. It is expected that future smart packaging food contain more complex, remote-readable non-visual information. Safety labels and radio frequency identification (RFID) tags are at the beginning of an electronic tag, in addition to product identification information, date of production, price, electronic tags can be used as time - temperature, leakage, or freshness indicator.
