ABSTRACT:
A method for coating paperboard comprising heating paperboard to a temperature sufficient to remove at least some moisture from the paperboard; applying an aqueous dispersion of at least one water-dispersible polymer to the paperboard product; heating the paperboard to at least partially cure the water-dispersible polymer; and cooling the paperboard to at least 160 degrees Fahrenheit to reduce the tackiness of the cured water-dispersible polymer.
