Heat-stabilized polyester films optimized for printing by conductive inks
Hanita Coatings offers heat stabilised PET films with a print adhesion-promoting coating, specifically for flexible printed
electronic applications. Using Hanita’s heat stabilised, coated PET film will help provide the dimensional stability and increased ink anchorage required for the successful printing and processing of:
-
Flexible electronics
-
Advanced displays
-
Membrane touch switches
The print adhesion promoting primer ensures optimal bonding of silver conductive and other electronic inks, increasing the flexibility of the printed product, reducing cracking and ensuring maximum conductivity of the ink.
Hanita’s in-line heat stabilization process provides PET films with the high levels of dimensional stability demanded by the printed electronics industry. This treatment counters registration problems resulting from the mechanical stresses and high temperatures used in the thermal curing of conductive inks, which can trigger differential shrinkage of the substrate.
Hanita’s heat-stabilized polyester films typically provide a low thermal shrinkage level of 0.3% in the MD, and 0.1% in the TD at 150oC, ensuring minimal shrinkage when exposed to high temperatures.
Heat stabilized, top coated clear or white polyesters are available in 50, 75, 100, 125 and 175 micron thickness.
