A mailing device (210) has a body (215) with a window aperture (216). The aperture is covered by a film of transparent material bonded to the body. At least one line of weakness (128) is formed in the body at least partially encircling the film to enable the film to be separated from the body for recycling. The line of weakness (128) may be configured to define a strip (236) that extends across a front wall of the device. The strip (236) can be opened by tearing along the line of weakness to gain access to the interior of the device and to allow easy removal of the film. Alternatively, the line of weakness (128, FIG. 3) may completely encircle the film and define a tab portion (124, FIG. 3). In further alternative embodiments, the film (18, FIG. 1) has a tab portion (24, FIG. I) that is pulled to separate the film from the body. The film may be bonded using a peelable adhesive and may be bonded to an outside surface of the body. |
