ABSTRACT:
A single-ply is folded about a transverse fold line longitudinally offset from a median through the ply and folded about parallel substantially coincident axes to form first, second, third and fourth panels of a mailer assembly. Longitudinally extending lines of perforations define marginal tear strips and transversely extending lines of perforations on the second and third panels adjacent the middle fold line and adjacent a free end of the first panel register with one another to form an end tear strip adjacent the top or bottom of the mailer. Where a return envelope is required, one of the panels has a U-shaped pattern of heat-sealable adhesive to join a pair of registering panels one to the other, with another panel forming a closure flap bearing rewettable adhesive.
