Product Introduction
Mylar polyester film sheets are precision-cut sheets of biaxially-oriented PET (BoPET) film - a high-performance engineering plastic known for its exceptional tensile strength, dimensional stability, dielectric properties, and chemical resistance. Manufactured from virgin PET resin and available in clear, translucent, and opaque grades, our polyester film sheets are produced to tight tolerances with die-cutting precision of ±0.02 mm.
Commonly used as electrical insulation, thermal barriers, protective overlays, printing substrates, and industrial spacers, Mylar sheets serve industries including electronics, automotive, medical devices, optical equipment, packaging, and labeling. With a production capacity of 100,000 pieces or 10,000 m² per day and a 2–3 day proofing turnaround, we deliver high-volume consistency and fast custom development.
