An envelope with openable structure includes a front panel, a back panel and a closure flap. The front panel has a front inner and a front outer opposed surface, a front top edge, a front bottom edge, and a front first and a front second opposed side edge. The back panel has a back inner and a back outer opposed surface, a back top edge, a back bottom edge connected to said front bottom edge of said front panel to form a bottom folding line, and a back first and a back second opposed side edge connected to said front first and second side edges respectively to form a first and a second side folding line respectively. The closure flap is extended from said front top edge of said front panel and forms a front folding line therebetween for overlapping and adhering onto said back outer surface of said back panel. A tough and durable tearing member, having a predetermined width and length, is affixed within said envelope at a position adjacent and parallel to one of said folding lines between said front and back panels, and that said tearing member further has at least an end tag portion extending outside said envelope for grasping, thereby by tearing said tearing member along said back folding line, a smooth, neat and full cut is achieved to open said envelope.
