PET Film for Spiral Tube

PET film for spiral tube is slit into narrow strips and wound in a spiral pattern to form light, flexible insulating tubes. The film’s uniform thickness and smooth surface let the layers overlap evenly and bond firmly, giving the finished tube a consistent wall and a neat appearance. Its toughness prevents tearing under winding tension, and the resulting tube bends easily without cracking or collapsing. Spiral tubes made from PET are used as protective sleeves for wires, lead wires, cable harnesses, sensor leads and small electrical components. Custom slitting widths, thicknesses and samples are available for your tube winding production.
