What is the best way to protect and store an uncut sheet of baseball cards?

I would like it to remain flat.

Is there any type of holder especially made for uncut sheets that can be purchased somewhere?

Options I have read about: Mylar D, Melinex®, polyester. Which is best? What should I avoid?

This is only for preservation. Not to display.

I found this which looks good.

Do I need a backing?

There are giant top loaders you can buy

By keeping it far away from Martin Sports Cards.

You can also go to a hobby store and buy a very cheap poster frame with 4 plastic edgers/clips that keep the plexiglass in place. Usually comes with a paper or cardboard backing. They also come in various sizes.

If I were you I would buy a tube and roll it up. Less chances of it coming in contact with anything that could damage it.

Would anyone be against the Pulp Fiction Christopher Walken watch storage approach here ?

Do NOT roll it! I recently went through a bunch of stuff I had in tubes and the items that were thick like cardstock developed creases. The thin stuff was all good.

A giant top loader would work and then tape it to a stiff piece of cardboard.

That was my next question. How do I prevent warping?

Do I really want to tape it?

He meant tape the top loader to a piece of cardboard. Sheet is in top loader.

Thanks Dan! Exactly what I meant.

Thank you.

I keep mine is giant top loaders, and them put all of them between 2 pieces of card board that is clamped together to avoid the sheets sagging. Eventually they get framed.
