The present invention relates to a paperboard carton for packaging application, such as carrier for cans or bottle beverages, having a selective reinforcement to enhance strength properties. The selected areas of the paperboard carton are reinforced by coating with a water-based formulation containing a water-based polymer and fibers having a dimension of about 50 micron to about 2,000 micron in length and about 20 micron to about 1,000 micron in diameter.
