Abstract: Intermediates for matched mailer type business forms are constructed in four and six panel formats from a single sheet. Pressure sensitive adhesive discontinuous strips are disposed in marginal portions of the intermediates to align with each other when the intermediates are folded first about a center line, and then either a single longitudinal fold line, or first and then second longitudinal fold lines. The adhesive strips may include L-shaped portions at the intersections of strips. The marginal portions are separated from four or six main panels by perforations. The marginal portions adjacent the longitudinal edges of the sheet may have tractor drive openings. Using the invention standard size mailers containing multiple plies may each be constructed from a single sheet, by running the intermediates through a non-impact printer (e.g.
