ABSTRACT:
The present invention relates to a paperboard envelope which utilizes a single strip of tear tape having adhesive applied to both sides for sealing and opening. The envelope structure includes starter elements in both the sealing flap and the panel to which the sealing flap is adhered for assisting in the opening function. The improvement lies in extending the starter elements beyond the side edges of the envelope body to provide starter tabs that can be readily grasped to open the envelope.
