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.
A resealable packaging structure for housing products wherein the entire packaging structure comprises a laminate comprising an outer layer and an inner layer that are coextensive across substantially their entire areas, each of the layers having an upper surface and a lower surface and wherein, other than in an unadhered tab portion of the outer layer, the outer layer lower surface is adhered to the inner layer upper surface over substantially their entire surfaces, the laminate further comprising a repeatedly openable and closeable flexible structure which comprises:
