ABSTRACT:
A composite food packaging article having internal partitioning walls and corresponding method of manufacture is constructed from flat, machine formed paperboard. A pair of die cut and folded paperboard blanks are inserted within the opposing cavities of a blow mold. A hot-flow parison between the cavities expands to structurally unitize the folded paper blank into a fluid impermeable tray vessel.
