How thick is selphy paper? Mils or points?

[mdbj]

Make me crazy, been all over the internet, learned far more about selphy papers than I need in my head.

How thick are selphy prints/the postcard backs- are the postcards floppy or not?

thanks

Do you need absolute thicknesses, or just relative comparison?

Postcard paper would not be expected to be floppy. It would be a stiff "card stock". Label paper would be bendable, like 20 lb. to 28 lb. papers.
