Hi,

I attached a 4" x 6" piece of foil to regualr paper
with a couple of laser compatible labels. I attached
just the leading edge.to avoid wrilkes. The same
procedure that I used for the blue stuff.

I did smooth down the cut edges with my finger.

I noticed that it took less time (passes through the
laminator) to heat up. The paper seems to act as an
insulator. Phot papere takes many more passes than the
Staples paper.

Good luck and let us know your results.

Myc
