I have done some tests. I made some business card sized images and printed them on Xerox paper, matt coated one side, 95 gm/square metre. To form a two sided image I printed, using an ink-jet printer. The front and back were adjacent so that I could fold the result. I used Staples (the office supplier) glossy 125 micron (each side, 250 micron total) thick pouches and a domestic laminator.

Four tests:

1. No glue and left a margin of transparent laminate around the paper. This was ok, but I didn't want the margin if I could avoid it.

2. No glue and cut off the laminate at the edge of the paper. I thought it possible that the laminate glue might penetrate the paper and glue it together. No such luck, it remained as a folded sheet.

3. I glued the folded paper together with 3M Photo Mount spray and laminated the result. However vapour from the glue made the laminated result bubble up, although it shrank back to a flat card after a while. Trimming the margins off left me with a viable result with the images going to the edges of the card.

4. Did the same as (3) but I left the glued paper in a warm place (an airing cupboard) overnight. There was no bubbling and the final result was what I wanted.
