I also use Kapton Tape - I'm running my hacked GBC laminator at 330 degrees with
no problems. I got my tape on ebay- you can find some good prices usually.

have been tapping the pattern to the board with various types of tape and
removing them after a few passes to ensure equal heat transfer but they all
leave a sticky residue on the back of the pattern. Because of the glue left
behind, the pattern sticks to the carrier paper and tends to lift the pattern
off the board slightly when i rotate the board. Has anyone found a good tape to
use that can withstand the heat of a laminator without leaving glue behind. I
have tried the duck brand scotch tape and some tape made by fisher scientific.
This isnt a huge problem, my transfer was the best ive ever had, but the
transfer wasnt entirly complete on the edge that had the glue residue (paper
lifted off pulling on the traces). I was thinking masking tape or some of the
blue painters tape might be good.
