ITO-PET Conductive Film 5 Ω/sq 100×300 mm

The ITO-PET film requires strict edge-only handling to prevent coating damage and must be stored in a dry, dust-free environment at room temperature to avoid performance degradation. Thermal cycling from -40°C to 80°C is acceptable but performance variation must remain ≤1.3 after 120-minute exposure at each extreme.

• Thermal Cycling Tolerance: The film maintains performance variation ≤1.3 after 120-minute 80°C baking and 120-minute -40°C freezing, ensuring stability under alternating thermal environments.
• Optical and Mechanical Integrity: Haze ≤3% and 100% coating adhesion require minimizing surface contact and avoiding any creasing or folding of the substrate.
• Flatness Constraint: Curl ≤10 mm must be preserved by storing the film flat between rigid backing boards and not subjecting it to mechanical stress.
• Surface Contamination Prevention: The ITO-coated side is protected by a removable cover film that must remain in place until immediately before use to prevent particulate contamination.
• Long-Term Storage Conditions: Store the film in a dry, dust-free environment at room temperature, away from direct sunlight and humidity sources to prevent oxidation or degradation.

Follow these steps to safely handle the ITO-PET film without compromising its conductive coating or optical clarity. Proper storage and edge-only manipulation are critical to maintain the film's performance for flexible electronic device fabrication.

1. Inspect the film
   Inspect the film for any visible damage, contamination, or creasing before removing the protective cover film.
2. Peel the protective cover film
   Peel the removable protective cover film from the ITO-coated surface immediately prior to use to minimize particulate deposition.
3. Handle by edges only
   Handle the film by edges only and avoid any contact with the ITO-coated surface to prevent contamination or abrasion.
4. Store unused film
   Store the film in a dry, dust-free environment at room temperature, flat between rigid backing boards, when not in use.
5. Avoid mechanical stress
   Avoid folding or creasing the film at any time to preserve the integrity of the conductive ITO layer and substrate.

This ITO-PET conductive film offers a 5 Ω/sq sheet resistance with ≤3% haze and broad thermal cycling stability from -40°C to 80°C, available in three thicknesses (0.05, 0.125, 0.175 mm) for mechanical flexibility tuning. The magnetron-sputtered ITO coating provides consistent conductivity across the 100×300 mm sheet, but users must balance coating thickness against optical transmittance and handle the film carefully to avoid surface damage.

Positive

• Broad thermal cycling stability: Performance variation ≤1.3 after both 120-minute 80°C baking and -40°C freezing, enabling reliable operation in alternating thermal environments without delamination or resistance drift.
• Three thickness options for flexibility tuning: Available in 0.05 mm, 0.125 mm, and 0.175 mm thicknesses, allowing researchers to balance substrate flexibility against handling robustness for specific experimental configurations.

Trade-offs

• Conductivity-transparency trade-off: Increasing ITO coating thickness reduces surface resistance but correspondingly decreases optical transmittance; users must select the appropriate thickness based on application requirements.
• Handling and storage sensitivity: The ITO-coated surface must not be touched; the protective cover film should be peeled immediately before use to minimize contamination, and the film must be stored in a dry, dust-free environment at room temperature without folding or creasing.
