    Abstract: Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

    Abstract: A flexible packaging laminate has built-in opening/reclose and tamper-evidence features by forming the laminate from an outer structure joined in face-to-face relation to an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting a flap or the like 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. The outer score line includes at least one tab positioned within a heat seal region of the laminate.

    Abstract: The invention comprises a package for reactive materials comprising a panel defining a first end, a second end opposite the first end, and at least two side edges. The panel comprises at least one film layer, an adhesive adjacent the film layer, wherein the adhesive is pattern applied such that it is disposed within an interior region of the film layer and wherein a perimeter of the film layer is adhesive-free adjacent each of the first end, second end, and side edges, and a release liner comprising a substrate layer and a cured silicone layer. The release liner is adhered to the film layer via the adhesive, the substrate layer of the release liner is disposed adjacent the film layer, and a perimeter of the release liner is smaller than the perimeter of the film structure. In an embodiment, the panel comprises a tubular body and the side edges are sealed together to form a fin seal, the first end is sealed closed to form an end seal, and the second end is sealed closed to form an end seal.

    Abstract: Improved packages and methods for constructing packages are provided that reduce or prevent leakage into or out of the package. In particular, the package includes a base member and a lidding member with a reinforced perimeter portion that blocks channels that may form at the interface between the base member and the lidding member from extending to the edge of the base member, such that, e.g., liquids have no path to the package exterior. The perimeter portion may be a thicker region of a first film of the lidding member (e.g., a polyethylene emulsion), or the perimeter portion may be formed using permanent adhesive. Frangible layers and/or cut lines may be defined in the material of the base member or the lidding member to allow a controlled break to occur when the lidding member is peeled away from the base member to provide access to the package contents.

    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.
