<p>A shipping enclosure in the nature of an envelope includes a sealing flap (22) of greater width than the envelope adapted to be folded over the mouth of the envelope, the flap including extensions (32, 33) arranged to be bonded to the face of the envelope opposite the face defining the primary seal. A tear strip (27) is interposed between the hinge connection (24) of the flap to the envelope and the bond line (29) for facilitating opening of the envelope, and for encircling and, hence, reinforcing the enclosure mouth prior to opening.</p> |
