A coated paperboard () comprising: a base substrate () having a brightness of about 65 or less measured using TAPPI T452 and a coating () on at least one side of the base substrate, wherein the base substrate comprises: one or more opaque layers () including a white filler, wherein the opaque layer covers the base substrate so that visibility of the base substrate through the opaque layer is substantially eliminated; a barrier layer () covering the opaque layer; wherein the barrier layer substantially prevents aqueous fluids from contacting the opaque layer, and wherein the coated paperboard has a brightness on the side of the base substrate with the coating of about 65 or more measured using TAPPI T452, and a wet brightness drop, on the side of the base substrate with the coating, of about 30 or less, measured using the wet brightness drop test.

Coated substrate and system and method for making the same

A process for preparing a starch dispersion may include combining a feed starch and an aqueous liquid to form a starch slurry. The starch slurry may be subjected to a first degradation treatment to form a first mixture. A temperature of the starch slurry during the first degradation treatment may be less than a gelation temperature. The first mixture may be heated to a temperature between the gelation temperature and a solubilization temperature. The heated first mixture may be subjected to a second degradation treatment to form a second mixture. The second mixture may be sheared to form the starch dispersion.

Process for production of high solids starch dispersion using multi-stage degradation

A process for making paper, comprising contacting an anionic binder with a cationizing agent to make a cationized binder, contacting the cationized binder with an anionic pigment to form a binder/pigment agglomerate, contacting the agglomerate with an aqueous slurry of fibers, and forming a paper product from the slurry. The agglomerate may reduce the total cost of the paper product being produced while maintaining the strength of the paper at acceptable levels.
