Abstract

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. 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.
