A coated paperboard container includes a paperboard substrate and an aqueous barrier coating on the paperboard substrate. The coated paperboard container has a repulpability yield of 75% accepts or greater, a sidewall seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 50% or less.

Coated paperboard containers having an aqueous barrier coating

A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.

Smooth and low density paperboard structures and methods for manufacturing the same

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:1=29.15+11.95&#x2212;0.074152.

Low density paper and paperboard with two-sided coating

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 Ypounds per 3000 ft2, wherein Yis a function of the caliper thickness (X) in points and is calculated as follows: Y=29.15+11.95X&#x2212;0.07415X2.

A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface in a pressure nip while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.

Method for treating a substrate

A paperboard including a solid bleached sulfate paperboard substrate and a coating applied to 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 3 microns, the basis weight being at most about Ypounds per 3000 ft, wherein Yis a function of the caliper thickness (X) in points and is calculated as follows: Y=3.79+13.43X&#x2212;0.1638X.
