A mailer form adapted to be advanced through a folder-sealer apparatus having a first roller and a second roller, with the second roller having a number of sealing projections extending therefrom, includes a first edge portion having a first number of pressure sensitive adhesive patches disposed thereon. The form also includes a second edge portion having a second number of pressure sensitive adhesive patches disposed thereon. The mailer form is configured such that during advancement of the mailer form between the first roller and the second roller (i) the mailer form is folded by the first roller and the second roller such that the first number of pressure sensitive adhesive patches are aligned with the second number of pressure sensitive adhesive patches, and (ii) both the first number of pressure sensitive adhesive patches and the second number of pressure sensitive adhesive patches are aligned with the number of sealing projections of the second roller. A method of folding and sealing a mailer form is also disclosed.
