I use 140gsm Glossy photo paper from Choice Stationery, but they also do 180gsm.
I have not had any problems with printing and using for passports or driving licences. Just remember that both passport and driving licence photo's must now be on a white background. My passport photo is on a blue background, taken about 9 years ago. But for some reason best known to themselves the background now has to be white.
