摘要：
A paper or paperboard including a cellulose substrate and a coating applied to each side of the paperboard substrate to form a coated structure, the coated structure having a basis weight, a caliper thickness and a Parker Print Surf smoothness, the Parker Print Surf smoothness being at most about 2 microns, the basis weight being less than about Y1 pounds per 3000 ft2, wherein Y1 is a function of the caliper thickness (X) in points and is calculated as follows: Y1=29.15+11.95X−0.07415X2.
