Abstract
A flexible packaging laminate formed by an outer structure joined to an inner structure. Score lines are formed in both structures to form a flap that is lifted to open the package. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate. The outer score line includes at least one tab having one end integrally joined to an outer edge of the flap and an opposite end anchored to a portion of the outer structure spaced from the outer edge, the tab being torn through upon initial creation of the opening through the flexible packaging laminate.
