ABSTRACT:
This invention relates to paperboard laminates for pharmaceutical blister packaging. Such structures of this type, generally, employ a hot melt adhesive and calcium carbonate (CaCO.sub.3) blend which is capable of sealing to polytrichlorofluoroethylene (Aclar.RTM.). Aclar.RTM. film is commonly used for high moisture barrier packaging in pharmaceutical applications.
