发明名称 Easily openable reusable envelope
摘要 An improved adhesive sealed envelope is provided with a tear away portion extending there across in an area of the back panel lying under the adhesive seal of the top flap when the envelope is sealed, the tear line defining the tear away portion being hidden by the top flap. The envelope is opened in the natural way by grasping the flap and pulling upwardly causing the envelope to open along the tear line, thereby creating a larger access opening.
