I have a wood island cabinet that came out of kitchen. Its made of 10 ply laminated wood see pic. I'm look at installing this it on outside porch its completely covered an would have to be pretty extreme weather for water to get where it's gonna be installed. my main concern is humidity as I live in Central Virginia. Really high humidity in summer time. wondering if it should be sealed or if it be fine since it not in direct weather.
HAPPY PUPPY!
Tighten the cabinet up.

The prior suggestions will SLOW the deterioration of the plywood. That grade of plywood WILL deteriorate far faster than you want when exposed to weather. Sealing isn't something you can effectively do to plywood used for indoor cabinets.

I agree with oil field trash. Marine-grade varnish is your best bet. At least two coats, on every single part of it.

I would recommend Minwax Helmsman spar-urethane varnish. It is designed for use outdoor and even on parts of boats. It has just a little bit of stretch to it so it can expand and contract with the wood as the temperature changes. Be sure to seal all parts of the piece inside and out as well as all edges.

Giving a coat of poly, stain, or paint will always add durability
