Hi all, I am trying to laminate two ITO-coated PET thin films together with heating (I believe the temperature generated by my laminator is above 80 Celsius degree), but they did not stick together even a little bit. I have checked online for a few articles, laminating PET with heating (above 80 degree) seems straight forward, but why does it not work in my case? Did I miss anything? Please advise! Thanks a lot!
