Preserving my Rubber goods?

[thudpucker]

Some times these Rubber things will stick together. I've had to throw lots of them away.
What can I do about keeping them from sticking?
Do I have to put each in a different sack?
Do you guys put any kind of attractant on the Rubber stuff?
How about a Talcum Powder to keep them apart? OR maybe Corn meal?
