Substrates made of simultaneously oriented PET films for printed electronics

The advantages of Brückner’s LISIM® technology of BOPET films used as substrates for printed electronics has been shown.

 

Printed electronics are an area of great interest to the electronics industry sector for quite some time. Applications of printed electronics comprise RFID tags, sensors (e.g. for glucose meters), batteries, lightning and displays.

 

On the Brückner Pilot line PET films have been stretched simultaneously at different MD stretching ratios and different annealing temperatures. The thermal expansion of the BOPET film samples parallel to MD and TD and also the refractive indexes of some selected samples have been analyzed. The advantages of Brückner’s LISIM® technology in order to optimize the co-efficient of thermal expansion of BOPET films used as substrates for printed electronics applications has been shown.
