Kitchen countertops have a laminate on one side only, yet they don t warp.

On second thought, counter tops are not plywood, but MDF or particle board.

Laminate counter can warp if it’s not fastened to something rigid like a cabinet box. I’ve always used laminate backer to avoid the issue. It’s the same phenolic material used for laminate but without the decorative plastic coating.

Phenolic CNC tables are prone to warping too which is why aluminum tables are preferable.
