Get the pink ziplock 4 mil ones. They come in lots of sizes depending on the size of your holders. Best advantage is you don't need to buy a case.

10x8 empty black plastic paper bags work well and they are a good light barrier as well.

I think he is referring to black plastic bags that come inside of boxes of 8 x 10 photographic paper.
