A continuous mailer type business form includes a top ply, a single or multiple part insert ply, and a return envelope. The return envelope comprises first and second plies secured along three edges, with a fourth edge open, and one of the first and second plies is adapted to be folded over the open edge to close it. The second ply comprises marginal areas of adhesive adjacent at least one edge with tear off perforations disposed within the marginal areas of adhesive. The marginal areas of adhesive connect the first and second plies on one side of the perforations, and the second and top plies on the opposite side of the perforations. The insert and first plies are unconnected to the top ply by the marginal areas of adhesive. The marginal areas of adhesive may comprise longitudinally spaced diagonal strips, with the width of the marginal areas of adhesive approximately the same on the opposite sides of the perforations. Preferably the marginal areas are provided along two opposite edges of the return envelope, while a continuous strip of adhesive secures the first and second plies together along the edge opposite the open edge of the return envelope. |
