The flexible circuit board in the display and the optical grade film in the module structure (such as reflective film, diffusion film polarizer, etc.), also be made into a released polyethylene terephthalate film that can protect the optical adhesive layer on the optical film, so that its performance and loss will not be affected by volatilization, physical impact, corrosion, and other factors during storage, transportation.

As the core part of the solar panel, the polyester pet film for the solar panel protects and supports the silicon cells, and has excellent anti-aging, water penetration, high temperature and humidity resistance, insulation, and other properties. The mechanical properties and insulation properties can meet the requirements of the solar backplane for the long-term aging resistance of the base film.

The base polyethylene terephthalate film is used to produce commodity labels, refrigerators, washing machines, cabinets, and other panels, cable shielding, air conditioning pipe packaging and waterproof materials, building materials.

As a flame-retardant film base polyethylene terephthalate film, it can play a role in flame retardancy after downstream coating, composite, and other processing procedures, and is widely used in the electromechanical industry as an insulating material. After being coated with flame retardant adhesive downstream, it can be used for the packaging of lithium batteries and as the insulating material in large capacitors.
