PET Coil - T 0.075mm W 914mm L 0.5m

Polyethylene Terephthalate (PET) Coil is PET film in a continuous spooled format, available in amorphous and biaxially-oriented (boPET) structures at thicknesses from 0.0005 mm to 0.5 mm — covering the range from ultra-thin capacitor winding stock through to heavier converting and lamination grades. The coil format is the natural choice for roll-to-roll processing, automated cutting, and high-volume converting operations where consistent geometry and uninterrupted length are as important as the material's intrinsic properties. Amorphous PET coil offers superior optical clarity and thermoformability, making it well suited to applications where forming or bonding operations follow conversion. Biaxially-oriented PET (boPET) coil delivers tensile strengths of 190–260 MPa with excellent dimensional stability and low moisture uptake — 0.1% over 24 hours — providing the process consistency that high-precision manufacturing demands across the full roll length. With a dielectric strength of 17 kV/mm and volume resistivity above 10¹⁴ Ω·cm, PET coil is well established as a winding dielectric in capacitor manufacture and as a substrate for flexible circuit and display film production. In research and pilot-scale production, the coil format minimises handling-related variation and supports consistent results across coating, deposition, and surface treatment processes where structural consistency and tight thickness tolerances are essential.
