I use a Fellows SPL 125. It has speed settings, I run it on the slowest setting. Takes like 10 seconds for the board to go through.
Actually, almost all my boards are double sided. The preheat makes the paper stick to the board, so both sides are lined up when I stick it in the laminator.

The better laminator made a huge difference, if you can replace the feed motor with something that you can slow down I suspect that would fix your issue. If the feed is too fast you don't get enough contact time for the PCB to heat up.
