ABSTRACT:
A bifolded mailer is provided with head and foot panels which are individually shorter than its middle panel but collectively longer than its middle panel. The middle panel is provided with a window flap which remains joined along its lower margin. For variably printing the mailer on one face, the window flap is first folded down so that its outer face is exposed on the inner face of the mailer. After variable printing is applied, the form is processed foot first, in the source of which the window flap is folded back up and patched in place, the head panel is folded up and an insert body is deposited in the resulting trough, the foot panel is folded down, and adhesive bands, which have been applied to various marginal regions of the mailer panels, are activated, for instance by heated platens, creating seals at the left and right ends and in the lap between the head and foot on the outside rear of the mailer. Opening the mailer is accomplished by tearing off marginal strips at the ends, and by pulling across another tear strip located in an external panel.
