ABSTRACT:
A return mailer assembly comprising a pair of outer webs and an intermediate web, the first and second outer webs forming a first envelope, and the intermediate and second outer webs forming a return envelope portion, separable from the other outer web. To facilitate and increase the speed of production of such assemblies, a dry-gummed paper stock is sued for one or both of the webs which form the return envelope portion. At least one of the inner surfaces of the return envelope forming webs, as well as an envelope sealing flap portion, are provided with a gummed composition, i.e., a rewettable adhesive. A moisture barrier is applied to preselected areas of one or both of the facing, inner surfaces of the intermediate and second outer webs to prevent activation of the gummed surface, except in peripheral border portions where the return envelope forming webs are joined.
