A Z-fold mailer type business form intermediate using patterns of pressure activated cohesive has the cohesive in patterns for both sealing along the end and side edges of the final form in the form of discrete elements spaced from each other in such a way that when the business form is in either roll or stack format the individual cohesive elements substantially do not overlap each other. The cohesive elements typically are in the form of rectangles for example those along the end edges and the fold lines having a length of about .9 cm with space in between them of about 1.3 cm. The cohesive patterns along the side edges may be spaced from each other not only in a dimension parallel to the end edges, but also where cohesive patterns are provided on opposite faces of the second panel of the intermediate, they may be positioned so as not to overlap in a dimension parallel to the side edges.
