Films Protective Company manufactures transparent conductive ito pet film for touch sensors, flexible electrodes, transparent circuits, and electronic film assemblies that need optical clarity and surface conductivity. The film uses an optical PET base with a single-side ITO conductive layer, with typical sheet resistance options of 10-15, 30-50, and 80-120 ohm/sq. It is supplied as roll or sheet material for projects where light transmission, electrode layout, and clean handling of the conductive side matter.
Product Overview
Transparent conductive ito pet film is used when a clear plastic film also needs to carry an electrical path. Films Protective Company coats PET film with a controlled ITO layer to create a flexible conductive PET substrate for sensor, display, electrode, and circuit conversion work.
Sheet resistance should match the electrode area, signal distance, contact position, and light transmission target. A 10-15 ohm/sq grade is usually chosen for wider transparent electrodes or longer conductive routes. A 30-50 ohm/sq grade gives a balanced option for many touch sensor and display-related structures. An 80-120 ohm/sq grade is often used for compact sensing zones, low-current paths, or designs where optical clarity is more important than the lowest resistance value.
The ITO side can be supplied with a removable liner for cleaner handling during slitting, laminating, die-cutting, printing, or bonding. Remove the liner before coating, electrical contact, or resistance measurement.
Benefits
- Selectable sheet resistance helps match electrode layouts, sensing areas, and signal paths.
- 125 um and 175 um PET options balance flexibility with handling stability.
- The ITO layer creates a transparent electrode surface with useful visible light transmission.
- Sheet material works well for testing, sample approval, prototypes, and short runs.
- Roll material suits continuous lamination, die-cutting, and roll-to-roll conversion.
- Conductive-side liner helps reduce fingerprints, dust, and light surface marks before processing.
Which Sheet Resistance Fits Your Touch Sensor or Flexible Electrode?
Sheet resistance should be chosen from the actual electrode design, not only from the lowest number on a data sheet. For a larger touch sensor pattern, a lower-resistance ITO coated PET film helps keep the signal more consistent across a wider conductive area. For small flexible electrodes, biosensor pads, or low-current transparent circuits, a mid or higher resistance grade may be enough and may give a better optical balance. After cutting, laminating, or patterning, test the finished part again because contact position, electrode geometry, and conductive path length can change the final resistance.

How Should the Conductive ITO Side Be Protected During Processing?
The ITO side is the working electrode surface, so it should be handled more carefully than a normal PET face. During slitting, lamination, die-cutting, or assembly, the removable liner helps keep the coated side cleaner. Before electrical connection, coating, or resistance testing, remove the liner and confirm the conductive side with a multimeter, surface resistance meter, or four-point probe. For laminated parts, marking the ITO side during sampling helps prevent reverse assembly.

FAQ
Is this film conductive on both sides?
No. The standard structure is single-side ITO coating on PET. The back side is non-conductive PET.
Can it be supplied in both rolls and sheets?
Yes. Films Protective Company produces roll material for converting lines and sheet material for sampling, testing, and small-batch work.
How do I choose the right sheet resistance?
Use lower resistance for larger electrode areas or longer signal routes. Use higher resistance for lower current flow or a stronger optical balance.
Should the protective liner stay on during testing?
No. Remove it before bonding, coating, printing, or measuring the ITO conductive layer.
