I haven't tried corrugated cardboard, but cardboard tablet backs and 6.0 and 2.5 micron SiC work pretty well as a field expedient. For me, at least!
And a 2 inch by 6 inch piece with 6.0 on one side and 2.5 on the other fits nicely in a plastic sandwich bag.
Even better, in my experience, is a paint stirring stick ( usually free from your paint store,) with leather on both sides. This also fits nicely in the plastic wrappers that newspapers use on rainy days.
I wouldn't imagine corrugated would be very good.
good idea with the paint stirs though.
