⚡ Enabling Printed Electronics with Functional PET Films ⚡

  • 26 August, 2026

On May 27, Toray Films Europe participated in a webinar organized by the PRINT’UP Institute on the technical specificities of films for printed electronics. The event gathered 38 professionals from across the printed electronics ecosystem, reflecting growing interest in innovative and sustainable substrate solutions.

Dr. Lucile Gambut-Garel, Innovation Manager at Toray Films Europe, presented how Lumirror™ PET Film technologies can support the performance, reliability, and sustainability of printed electronic applications.

 

A Broad Portfolio of Functional PET Films

Printed electronics require substrates that combine dimensional stability, printability, flexibility, durability, and excellent surface properties. Toray’s Lumirror™ BOPET films meet these demanding requirements by combining high performance with customization options.

Key features presented during the webinar:

            ✅ Tailored surface treatments for enhanced adhesion and printability (Lumirror™ 41.31)
            ✅ Low and Ultra-Low Shrinkage grades for improved dimensional stability (Lumirror™ 57.01 and 4131STB)
            ✅ Controlled surface textures from ultra-smooth to matte finishes (Lumirror™ 40.60 and 60.12)
            ✅ Optimized surface energy levels for various conductive inks (Lumirror™ 45.11 and 42.31)
            ✅ Hydrolysis-resistant grades for long-term durability (Lumirror™ XTRMPVG)
            ✅ Low-fluorescence films for sensitive optical applications (Lumirror™ H10LF)
            ✅ Pharmaceutical and specialty grades (Lumirror™ H10.10)
            ✅ Films containing recycled or bio-based content (Lumirror™ 10.50R and 60.01R)
            ✅ Material thickness reduction strategy (Lumirror™ 60.01) up to 4.5µ
 

Demonstrated Performance for Printed Electronics

One of the highlights of the webinar was the presentation of application trials conducted in collaboration with the PRINT’UP Institute.Tests performed using screen-printing processes with carbon, silver, and PEDOT: PSS inks demonstrated: Excellent ink adhesion | High conductivity levels | Surface characteristics impacting electronic performance.
 
Among the evaluated materials, Toray’s Lumirror™ 40.60 grade achieved particularly strong conductivity results, illustrating how film engineering can directly contribute to the performance of printed electronic devices.

 

Supporting the Next Generation of Flexible Electronics

From smart packaging and sensors to functional labels and emerging flexible electronic devices, PET films remain a key enabling material for innovation. Their recyclability, mechanical robustness, availability in thin gauges, and compatibility with a wide range of printing technologies make them an attractive solution for designers and manufacturers alike.
 
At Toray Films Europe, we continue to develop advanced film solutions that help our customers combine technical performance, sustainability, and cost efficiency.

 

 

Sustainability at the Core of Innovation

Toray is committed to reducing the environmental footprint of its Film solutions. Life Cycle Assessment (LCA) demonstrates continuous improvements in the carbon footprint of its PET and OPP Films.
 
Our sustainability efforts focus on down-gauging, recycled content, bio-based solutions, production efficiency, and resource management. Additionally, by recovering and recycling PET films, we aim to support a circular economy and further reduce the carbon footprint of printed electronics applications.
