ABSTRACT:
A process for reducing rollups in gypsum board panels when the panels are laminated with a laminate, is provided. A laminator is provided, as is at least one gypsum board panel, each panel having a face paper layer and a backing paper layer. Each paper layer has a coefficient of friction, and at least one of the face paper layer and the backing paper layer is treated with an agent for reducing the coefficient of friction and water absorbency. Next, a supply of laminate is provided and installed in the laminator. Then, at least one panel of the gypsum board is fed through the laminator, so that a layer of the laminate is applied thereon.
