Abstract
A process is disclosed for preparing a high quality paperboard product with high brightness and a defect-free glossy surface. The product comprises a structure consisting essentially of a paperboard substrate onto one surface of which there is first applied a coating of a pigmented polyolefin and a subsequent coating of a clear polymeric material such as a polyester. The brightness and loss achieved for the paperboard product is superior to conventional coated paperboard, cast coated paperboard, or other laminated paperboards currently in use.
