Keeping a plastic laminated plywood table top flat

since this is an outfeed table, and does not support the lumber near the blade it shouldn’t have to be ubber flat. actually – most outfeed tables are about 1/8” lower than the TS table since it only needs to support the lumber from dropping down too much, but not affect the lumber by being too hight so that it interferes with the cut.

to cut it short – I wouldn’t worry TOO much about it staying perfectly flat.

Yes you do have to seal the put laminate on the back; it’s Houston after all. the humidity will get to it. The torsion box will help to keep it flat, but even that will not be permanent. My torsion box bench top has some slight bowing, but it stretches a much longer span and takes much more weight than you are going to apply to your out feed table.

If the apron support system you fasten the top to is stout and flat enough, theres no need to laminate both sides. Laminate on one side can bow plywd in a free floating situation, but is no match for a hefty wood base. Which is why you rarely see counter tops laminated on two sides.

Laminate or seal the back side of the ply panel to make it stay flatter. Otherwise sounds good.

I plan on building this in a couple of weeks. Maybe this is something to help your decide design features.
