An intermediate for a mailer type business form, and a mailer produced from it, allow construction, from a single sheet of paper, of a mailer type business form that has a confidential integral insert closed on all edges. Confidential indicia is imaged on the interior faces of the insert, and is accessible only by tearing along at least one edge of the insert, which indicates tampering. Double fold, roll fold, or other folds may be provided for forming the mailer from the intermediate. For double fold and roll fold constructions, no security screening is necessary, yet the confidential indicia is substantially as secure as if security screening had been provided. |
