PET Film for Flexible Printed Circuit

PET film for flexible printed circuit use offers a light, economical and flexible base for circuits that must bend, fold or fit into thin devices. Its good dimensional stability helps keep printed or etched traces accurately aligned, and its smooth surface supports even conductive ink, copper foil and adhesive layers. The film is commonly used as a substrate, cover layer or stiffener in membrane switches, touch sensors, LED strips, wearable sensors and low-cost flexible circuits. It handles roll-to-roll printing, laminating and die-cutting, and keeps its shape through repeated light flexing. Different thicknesses, surface treatments and samples are available for your circuit design and trials.
