Getting toner to transfer on to a board depends on three things:

time
temperature
pressure

The final result is mostly a product of the three. You can reduce one (to an
extent) by increasing one or both of the others. Temperature is the
non-linear one. Too low and the toner never gets soft enough to stick, no
matter how much time and pressure. Too high, and the toner turns to liquid,
and squishes out and destroys all the fine details.

   If you are having trouble running very thin boards through your
laminator, try putting a second thin board under it to bring the thickness,
and thus the pressure back up. This only works, of course, if you are
transferring one side at a time. But if you are doing a double sided board
at once, add thick paper above and below the board with transfer paper so
that the total thickness will be better,

Just a guess.
