PET Coil

Industrial Applications

PET Coil is used across electronics, energy, display, and research sectors where a continuous, dimensionally consistent polymer film in a precisely controlled structure and thickness is required for roll-to-roll processing:

✦ Capacitor Winding & Dielectric Applications

PET coil is well established as a winding dielectric in capacitor manufacture, where its dielectric strength of 17 kV/mm, volume resistivity above 10¹⁴ Ω·cm, and consistent geometry across the full roll length ensure reliable electrical insulation performance in wound components.

✦ Flexible Circuit & Display Film Production

Used as a substrate for flexible circuit and display film production, where the coil format supports continuous roll-to-roll deposition and coating processes and biaxially-oriented grades provide the dimensional stability and low moisture uptake required for high-precision patterning and lamination.

✦ High-Volume Converting & Lamination

The spooled format suits automated cutting, slitting, and lamination operations where uninterrupted roll length and consistent film geometry are as important as the material's intrinsic properties, minimising downtime and handling-related variation in volume production.

✦ Forming & Bonding Operations

Amorphous PET coil's superior optical clarity and thermoformability make it well suited to converting processes where forming or bonding operations follow cutting, supporting applications in packaging, optical assemblies, and laminated components where post-conversion processing is required.

✦ Coating, Deposition & Surface Treatment

Used in pilot-scale and production coating, physical vapour deposition, and surface treatment processes where structural consistency and tight thickness tolerances across the full roll length are essential for reproducible results across batches.
