Thickest BOPET Film

Thickest BOPET Film is an extra-heavy-gauge biaxially oriented polyester film manufactured from high-grade PET resin through precision biaxial stretching technology. As the thickest specification of BOPET film, it delivers extremely high tensile strength, superior structural rigidity, excellent dimensional stability, outstanding high-temperature resistance and strong puncture and abrasion resistance. Compared with conventional BOPET films, this ultra-thick grade maintains exceptional mechanical performance and shape retention even under heavy load, high temperature and harsh industrial environments. It is widely applied in heavy industrial lamination, high-voltage electrical insulation, composite material structural reinforcement, high-temperature protective barriers, mechanical gaskets, heavy-duty packaging and high-performance graphic printing. We offer a range of ultra-thick specifications and support customization of width, surface treatment and roll length to meet your most demanding heavy-duty industrial application requirements.
