Abstract
A mailer type business form intermediate, and business form produced from the intermediate, are provided which provide a reply envelope as part of the mailer yet avoid blocking of pressure activated cohesive patterns associated with the mailer during fan-folding. The pressure activated cohesive patterns forming three side edges of the reply envelope are spaced and configured so that when intermediates are in fan-folded configuration the reply envelope pressure activated cohesive patterns are substantially non-overlapping so that blocking cannot occur. The pressure activated cohesive pattern forming one edge of the reply envelope can be provided by first and second series of pressure activated cohesive elements that are spaced from each other both in a direction parallel to, and perpendicular to, that side edge. A Z-fold mailer type business form is particularly advantageous.
