What is a Polyester film?

Polyester film is a thin film material made from polyester resin, known for its strength, durability, heat resistance, and excellent chemical resistance. It is typically transparent or translucent and is used in a wide range of applications, including as an electrical insulator, packaging material, and components for electronic devices. Polyester film is commonly used as an insulating material in electronic and electrical devices and as a dielectric in capacitors. It is also suitable for printing and lamination processes, thanks to its smooth surface and high transparency. Due to its excellent heat resistance and weatherability, polyester film is ideal for outdoor use or in harsh environments, providing long-lasting performance.

Application of Polyester film

１．Electrical Insulation: Polyester film is widely used as an electrical insulator in electronic device substrates and capacitors.
２．Packaging Material: Due to its high transparency, it is used in packaging for food and products.
３．Printing Applications: The smooth surface and high transparency make it ideal for graphic design and label printing.
