Abstract
A business form or mailer intermediate, includes a substrate sheet having first and second surfaces, first and second parallel longitudinal edges and first and second opposite ends, and at least a first transverse fold line formed in the substrate perpendicular to the parallel longitudinal edges. The first fold line divides the substrate into two or more panels. An address area on one of the panels, and a window opening defined in another of the panels are in alignment when the substrate sheet is folded so that the address area may be viewed through the window opening. A pattern of adhesive is provided on the substrate, surrounding at least one of the address area and the window opening. Folding the substrate results in a seal around the window opening.
