Composite: Paperboard and Plastlc Overlay

*These two papers showed an unusually large drop in pH as a result of aging, for reasons that are not clear. The presence of a good alkaline reserve normally holds pH fairly steady during aging. The important thing to note, however, is that the final pH is stIl reasonable. Possibly the calcium carbonate will buffer the paper within its natural range, 6.5 to 8.0, even with further aging. The papers may very well be long-lived, but without additional testing or other factors not covered here, it is hard to say much more about them.
