Package for Two-Way Mailing

A method for forming a two-way disk mailer, comprising the steps of:

• (a) defining first, second, third and fourth regions disposed left to right successively on a planar, rectangular sheet of foldable material having a left edge and a right edge defining a length substantially greater than a width, by placing first, second and third fold lines across the width of the sheet at right angles to the length such that the dimensions of the second and the third regions in the direction of the length of the sheet are substantially equal, the dimension of the first region in the same direction is greater than that of any of the four regions, and the dimension of the fourth region in the same direction is less than that of any of the four regions;
• (b) forming a first perforated, tear-off line proximate the first fold line;
• (c) providing a first glue region, being either of a self-adhesive strip with a peel-off protective cover, or a stripe of remoistenable glue, at the left edge of the sheet in the direction of the width dimension and joined to the sheet by a second perforated tear-off line;
• (d) providing a second glue region, being either of a self-adhesive strip with a peel-off protective cover, or a stripe of remoistenable glue, at the right edge of the sheet in the direction of the width dimension;
• (e) placing a pattern of adhesive on the second region;
• and
• (f) folding the third region over the second region, adhering the third region to the second, forming a pocket to enclose a planar disk on three sides.
