Ultra Thin PET Film

Ultra Thin PET Film is an extremely thin-gauge biaxially oriented polyethylene terephthalate (PET) film engineered for precision and micro-scale applications. Manufactured from high-purity PET resin through advanced precision stretching technology, it features ultra-light thickness, excellent dimensional stability, superior optical clarity, good tensile strength and reliable dielectric properties. Despite its minimal thickness, this ultra-thin PET film maintains uniform surface quality, good heat resistance and chemical resistance, delivering consistent performance in high-precision processing. It is widely used in microelectronic insulation, precision label substrates, thin adhesive tape backings, fine printing, optical components and high-density packaging applications. We offer a range of ultra-thin thickness specifications and support customization of width, roll length and surface treatment to meet your specific precision application requirements.
