Abstract
There is provided a tear tape opening system for packages constructed from a tearable substrate such as kraft paper, paperboard or corrugated board materials wherein the resulting tear line is substantially precisely defined with even tearing of the packaging material. The tear tape is adhered along an inside surface of the tearable substrate along the desired tear line of the package and the initiating segment thereof is defined by an opening tab formed at the initiation of the tear line in the package so that it may be grasped by the user to initiate opening. A system for guiding the tear along the desired tear line is provided by means of a guide tape or tapes which serves as an edge reinforcing for the tear lines produced by the tear tape being torn through the packaging material.
