Abstract
According to one embodiment, a process for applying an adhesive material onto a barrier sheet substrate is provided. The process includes providing an adhesive material having viscosity of at least about 10,000 centipoise at 250° F. The adhesive material is applied to a multitude of cavities on a surface of a first tool with a coater unit in close proximity to the surface. The adhesive material is transferred from the surface of the first tool to the substrate supported on a surface of a second tool and pressed against the surface of the first tool.
