ABSTRACT:
A bend and peel child resistant and senior friendly tamper evident package comprising a blister sheet having blister pockets projecting from a front side thereof, a rupturable foil layer being adhered to the blister layer and reinforcing the paperboard material adhered to the foil layer, the paperboard layer having a tear strip formed therein, the tear strip being defined by a cut into the paperboard layer from the side thereof adhered to the foil layer, the cut extending only a certain percentage of the total thickness of the paperboard such that a controlled delamination of the paperboard layer occurs when the tear strip is removed. This provides a precise reinforcement of the foil layer.
