Clear Adhesive Film Company is a manufacturer of ITO coated PET film for electronic and optoelectronic processing. Built on an optical-grade PET substrate, the film uses a single-side indium tin oxide coating to provide conductivity while maintaining visual clarity. It is supplied in roll or sheet form for touch sensors, display components and flexible electrodes. Grade selection should match sheet resistance, optical transmittance, haze and the converting route.
Product Overview
This ITO coated polyester film is made for electronic converting and optoelectronic component production. Depending on the grade, the ITO conductive layer is deposited on PET by vacuum sputtering or magnetron sputtering. The finished transparent conductive PET film can be slit into narrower rolls, cut into sheets or prepared for further processing.
The lowest resistance grade is not always the right choice. Touch-sensor projects may place more weight on conductivity and response, while display-related work often needs tighter optical control. Before batch release, review PET thickness, coating uniformity, resistance variation across the usable width or sheet area and surface condition. For repeat production, link the approved sample to agreed four-point probe positions and the converting route.
Benefits
- Balances conductivity and optical clarity in a PET-based functional film.
- Supports grade selection by sheet resistance, haze and light transmission.
- Uses multi-point resistance checks instead of one nominal reading.
- Available in roll and sheet formats for different converting routes.
- Brings slit-width control, coated-side identification and winding direction into approval.
- Supports repeat-order comparison against a retained approved sample.
What Should Be Verified Before ITO Coated PET Film Enters Slitting, Patterning or Flexible-Electrode Processing?
Before processing begins, verify the ITO coated side, PET thickness, winding direction, slit width and sheet dimensions. Handle the conductive surface with powder-free gloves and keep it away from worktops, dust and rubbing. Inspect scratches, stains, patches, creases and edge damage under controlled lighting before and after cutting. After slitting or patterning, repeat sheet-resistance measurements at agreed positions across the usable width or sheet area. For flexible electrodes and patterned circuits, an actual-material trial is more reliable than approval based on a nominal ITO PET film grade alone.

How Should Sheet Resistance, Optical Transmittance and Haze Be Balanced for an ITO PET Grade?
A lower sheet-resistance grade can improve conductivity, but it may not provide the best optical result for every device. Review the grade against circuit layout, sensing area, visible-light conditions and bending exposure. For display-related work, compare optical transmittance and haze with resistance uniformity after cutting or assembly. For sensor or flexible-electrode projects, compare the processed sample with the retained approved sample at the same positions. This gives batch reviews a practical reference instead of relying only on a datasheet value.
FAQ
Is ITO coated PET film available in rolls and sheets?
Yes. PET thickness, roll width, slit width and sheet dimensions should be agreed before production.
How should sheet resistance be measured?
Use a four-point probe method and measure several positions across the usable width or sheet area. One reading is not enough for batch approval.
Can the film be used for flexible-electrode processing?
Yes, after actual-material validation. Tight bending, folding, hard-surface contact and rubbing should be avoided because they may affect the ITO conductive layer.
What should be checked before a repeat order?
Compare sheet resistance, resistance uniformity, optical appearance, dimensions, coated-side identification and surface quality with the retained approved sample and agreed converting route.
