ABSTRACT:
A multi-compartment envelope which is resistant to tearing includes a first sheet folded along a medial line to define a front and back panel and a second sheet whose margins are adhesively secured to the interior surface of the front panel. A slot in the front panel permits access to the pocket formed by said front panel and the second sheet adhered thereto while a second pocket is formed in the envelope by adhesively securing lateral flaps on the back panel to the front surface of the front panel thereby providing a reinforced construction.
