<p>The envelope has a closure flap (307) that is divided into two sections (307A, 307I ) in a 1:1 ratio by a fold line. One of the sections has an adhesive tape that fixes the closure flap on back side of the envelope, such that both sections of the closure flap are laid on a bottom flap (302) to close the envelope. The length of the closure flap is approximately equal to the total height of the bottom flap.</p> |
