Business form or mailer intermediate

A mailer or business form intermediate adapted to be folded and mailed comprising:

• a substrate sheet having first and second surfaces, first and second opposite parallel longitudinal edges, and first and second opposite end edges;
• first, second and third transverse fold lines formed in said substrate perpendicular to said parallel longitudinal edges, dividing said substrate into first, second, third, and fourth panels, said first fold line separating said first and second panels, said second fold line separating said second and third panels, said third fold line separating said third and fourth panels, said second, third and at least one of said first and fourth panels having substantially the same longitudinal dimensions, said second and third panels having an absence of transverse lines of weakness adjacent to said second fold line;
• a first adhesive pattern provided on said second surface of at least one of said second and third panels adjacent said longitudinal edges, a second adhesive pattern provided on said second surface of at least one of said first and fourth panels adjacent said longitudinal edges, a third adhesive pattern on said first surface of at least one of said first, second, third and fourth panels so that when said substrate is folded first about said second fold line then about said first and third fold lines said second surfaces of said second and third panels lie in contact forming a reply envelope, and said second surfaces of said first and fourth panels lie in contact;
• a transverse line of weakness adjacent to and extending parallel to said first or third fold lines thereby defining a return envelope closure flap;
• and
• a fourth adhesive pattern disposed on said closure flap.
