Carpentry and Woodworking - Sliding assistance for "drawers"

I am building a closet system beneath a set of stairs. It is quite deep, so instead of building drawers, I have decided to build sliding shelves instead. That is, the drawer space is defined and I am building just the front face and bottom panels of what would be the drawers. This way I can use baskets to store things and just slide them in and out of the space.

I am building the drawer/sliders in 1/2" mdf. Is there a simple product I can use to make sure these slide easily? I do not want to use rails or formal sliders because it will make the project too expensive. I was wondering if there is some kind of silicone tabs or something of the sort that I can just add to the underside of the slider that will help keep it slippy?

As it is, the mdf slides pretty easily on itself, but I would like to add something to keep it that way in the future.

Any suggestions?

Self-lubricating tape for protecting the sliding surfaces.

Hope this helps.

I cant think of the name of it but at a woodworkers supply store there is a spray that is used on table saw tops and such to make the wood slide more easily. Or you can use perifin wax or even bees wax.

Thank you both. These are some really good ideas. I had thought about wax myself, but I think that I like the idea of the nylo-tape - same idea but way more hi-tech and likely to last longer or provide less maintenance needs.

Now all I need to do is find it here in Canada!
