<p>The invention consists in a blank for an envelope including a sheet of material having two spaced apart substantially parallel fold strips dividing the sheet into a back panel, a front panel and a sealing flap. The sealing flap has a pair of adhesive strips thereacross, one adjacent the fold strip between the front panel and the sealing flap, and the other being adjacent the distal edge of the sealing panel. A tear strip is therefore provided between the adhesive strips so that, in use, the sealing flap can be folded onto the back panel and the distal adhesive strip adhered to the back panel to close the envelope. The tear strip is opened to open the envelope, and the adhesive strip adjacent the fold strip to the front panel is then adhered to the back panel to reclose the envelope for its second use. In a preferred embodiments the tear strip covers at least part of the return address during the first mailing.</p> |
