Abstract
A mailer type business form is constructed from an intermediate having a plurality of pressure activated cohesive cooperating patterns, and a card is mounted on or with the intermediate. Despite the fact that a card is included, because of the provision of surface manifestations in the intermediate, and/or because of the relative thicknesses of the card and the intermediate, the mailer may be sealed by steam rolling rather than requiring selective edge sealing. A surface manifestation may comprise a cutout with a patch, or a folded over portion of the intermediate, retaining the card with the intermediate during processing. Alternatively, first and second thinned portions of the sheet of paper, disposed on opposite sides of a fold line so as to cooperate and hold the card when the sheet is folded about the fold line, may be provided, the thinned portions provided by embossing, for example. The card typically has a thickness substantially equal to or less than that of the intermediate; for example, the card may have a thickness of about 7 mil, while the sheet of paper forming the intermediate is 38 pound ledger paper, which also has a thickness of about 7 mil.
