Abstract
A paperboard carton constructed from an integral paperboard blank has an improved pull tab tear strip opening. The carton contains at least two layers of paperboard in the area where the pull tab tear strip opening feature is located. The pull tab tear strip is an integral part of the outer layer. The pull tab tear strip is bounded along one elongate side by a cut line of weakness having a plurality of through cuts and along a second elongate side by a partial cut score line which facilitates ply separation of the outer panel adjacent this side during carton opening.
