This Heat Stabilized BOPET Film is a biaxially oriented polyester film specially processed through a heat stabilization step to achieve ultra-low thermal shrinkage and excellent dimensional stability. As a low shrinkage BOPET film, it maintains flatness and precise dimensions even after exposure to high processing temperatures, making it an ideal substrate for electrical insulation, motors, transformers and flexible circuits. The film retains the inherent strength, dielectric performance and chemical resistance of polyester while offering superior thermal endurance for demanding applications. Available in thin gauges from 4.5 to 12 microns with customized widths, it delivers consistent thickness control and clean, defect-free surfaces roll after roll. Manufactured under ISO9001 and ISO14001 certified production, it meets RoHS and REACH requirements for electronic applications. Converters and OEMs choose this heat stabilized polyester film for components that must hold exact dimensions through soldering, curing and lamination processes, reducing rejects and improving long-term reliability. The heat stabilization process also relaxes internal stress, so the film resists curling and wrinkling during slitting, printing and die-cutting, giving downstream processors a smooth, predictable material that runs consistently at high speed.
