Abstract
An envelope having a compartment and a sealed display rack hole is made from a single blank and has a front panel, two side flaps, a top flap, and a bottom flap. Each flap is integrated with the front panel and folds around a respective fold line to form the compartment. The front panel and either the top or bottom flap each have a display rack hole disposed to register with one another when the flap having the display rack hole is folded around its fold line. The front panel is affixed to the flap having the second display rack hole, preferably with adhesive or by heat sealing, to create an area that seals the display rack holes from the compartment. In preferred embodiments, the front panel has a window covered with transparent sheet.
