Product Introduction
We adhere to scientific development and provide the best PE Coated Base Paper Roll, Polyester Film, Yellow Glassine Paper Roll and services to our customers through technological innovation. We constantly innovate our business model to achieve leapfrog development. We uphold the enterprise spirit of integrity, team, professional, innovative, and insist on independent research and development of technology for a long time. In order to improve the production efficiency and ensure the quality of products, it is the key to choose a manufacturer with professional experience. We replace independent competition with mutual benefit, mutual trust, mutual reliance and mutual assistance to achieve a win-win situation for workers, enterprises and society.
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.
