Silicon oxide coated polyester films

Silicon oxide film (SiOx) is an interesting material in the field of the food and pharmaceutical technologies as well as the microelectronics technology. SiOx film possesses a high gas barrier property besides high thermal stability and high electrical insulation. Therefore, SiOx-coated polyester (PET) film is a possible material used for packing to protect foods or medicines from the deterioration by oxidation.
