Abstract:
A method for coating paperboard including the steps of preparing a web of cellulosic fibers, the web having a basis weight of at least about 85 pounds per 3000 ft2, calendering the web at least once to form a paperboard substrate, wherein each of the calendering steps is performed without substantially introducing moisture to the web, and applying a basecoat to at least one surface of the paperboard substrate to form a coated paperboard structure, the basecoat including at least one pigment, the pigment having a sediment void volume of at least about 45 percent, wherein the coated paperboard structure has a Parker Print Surf smoothness of at most about 3 microns.
