I see something similar with my paper, it tends to rip off the board
outline if i do not draw a second, wide, outline around it to anchor the
paper to the board. I always thought the paper is shrinking and causing
the problem this way.
You can try several things. Run the paper through your laminator a few
times before use to "set" the size.
After printing, scratch the back of the paper with sandpaper or a brass
brush to open the surface and allow water faster access.
Draw a wide outline around the actual board outline to guard it. Use
another paper.
I throw the boards into water still hot, but i have also let it cool with
the same result.
