Abstract: The invention comprises, in an embodiment, a resealable packaging structure comprising a container having a bottom and at least one sidewall extending upwardly therefrom, wherein the sidewall terminates in a flange. A flexible resealable lid is sealed to the flange. The lid comprises a polyethylene terephthalate layer disposed adjacent the flange, a pressure sensitive adhesive layer disposed adjacent the polyethylene terephthalate layer, and an oriented polypropylene layer disposed adjacent the pressure sensitive adhesive layer. The polyethylene terephthalate layer comprises a laser scored line which penetrates through the thickness of the inner layer but not through the outer layer and defines an opening portion that can be lifted out of the plane of the inner layer, thereby creating an opening through the lid defined by the laser score line.

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.

Abstract translation: 通过将层叠体形成为具有与内部结构面对面连接的外部结构的两部分结构，形成柔性包装层压体以具有内置的开口和重新闭合特征。 在两个结构中形成刻痕线，以通过将两个结构的开口部分（例如，翼片等）提升到层压板的平面之外，以使得能够通过层压体形成开口。 通过外部结构的刻痕线限定通过内部结构的刻痕线的开口较大，使得外部结构的边缘区域延伸超过内部结构的开口部分的边缘。 使用压敏粘合剂将边缘区域重新粘附到邻近通过层压体的开口的内部结构的下面的表面。
