ABSTRACT:
An intermediate for a C-fold mailer type business form is provided that does not cup or distort as a result of pressure sensitive cohesive provided on both the face and the back of the same panel. This improves the processing of the intermediate through cut sheet laser printers and post-processing equipment, and allows for easier stacking during manufacture. A sheet of paper having first and second faces and opposite parallel longitudinal edges has first and second transverse fold lines forming a sheet into three panels, and first and second longitudinal lines of weakness forming longitudinal marginal portions with the longitudinal edges. A first pattern (such as spaced quadrate cohesive elements) is formed in the marginal portions of the first face of the third panel while a second pattern of pressure cohesive elements is formed on the second face of the marginal portions of the third panel, the second pattern of elements staggered with respect to the first pattern so that cupping or distortion of the sheet at the third panel is substantially prevented. Other patterns of pressure cohesive formed on the marginal portions cooperate with the first and second panels to seal the longitudinal edges of the mailer, the other patterns typically also comprising spaced quadrate cohesive elements. A mailer is formed from the intermediate by C-folding the sheet about the first and second fold lines.
