Abstract: A method of forming a flexible packaging laminate (30) that has a reclosable opening (20). The method includes forming a two-part laminate that has an outer structure (40) joined in face-to-face relation with an inner structure (60). Score lines (122,142) are formed in both structures (40,60) 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 (122) through the outer structure defines a larger opening than the score line (142) 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 (92) is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.
