The paste is generally some form of "mineral ice" (like people use) it is meant to pull out heat and tighten the leg. The paper vs plastic is for a few reasons- should the wrap slip or start to come off, the paper will generally tear, where plastic could bunch up and cause a pressure point and injuring the tendons. Another reason is the paper breathes better than plastic, if you are trying to draw heat out and it can't leave the bandage because plastic is holding it in, A. You are not accomplishing what you set out to and B. It could blister the horse's leg. That is why when "sweating" a horse's leg with furazone etc, you use saran wrap instead of paper, because you want to hold the heat in.
Hope this helps!
