Cap tissue is the cheap tissue used by stores (for packing ceramics,
clothing, etc).  If it is bleached, it is not likely acid-free, but
try testing it with a pH pen or other pH testing method to be
certain.  Even if it tests neutral or alkaline, due to buffering,
you should be cautious about its use.
