Abstract: A single-ply of paper in web form continuously forms one-piece statement mailers by first die-cutting appropriate portions of the mailer to form a window for a return envelope, and inset edges for a bang-tail and payment coupon. Non-personalized and personalized information is printed on the single ply in various panels thereof. By repeating sequences of applying glue and folding the web into various panels, a complete statement with personalized and non-personalized information can be provided an addressee. Additionally, fugitive glue lines are provided in the return envelope to space the inserts, i.e., a payment coupon and remittance, from edges of the return envelope to facilitate opening of the envelope by automatic mail openers. Further, charge cards are releasably secured to one of the panels such that, when the ply is folded to form the mailer, at least two panels lie on opposite sides of the cards within the mailer.
