    摘要: The invention comprises an ovenable packaging structure having an integral one-way valve. The laminate structure comprises an outer layer having a cut line which defines a flap that is separable from the outer layer, wherein the outer layer is adhered to an inner layer having a cut line which is offset from the outer cut line and defines a portion that is separable from the inner layer along the inner cut line and defines an opening into the packaging structure. The adhesive between the layers comprises, in an embodiment, a channel of pressure sensitive adhesive which surrounds both the outer cut line and the inner cut line, wherein the channel of pressure sensitive adhesive defines the perimeter of at least one adhesive-free valve chamber within said channel. The valve chamber comprises at least a portion of the outer cut line and the inner cut line.

    摘要: 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.

    摘要: The present invention relates to a resealable membrane lid for a container comprising a peelable portion and a removable portion. When the resealable peelable portion is peeled back, the seal onto the container is not disturbed. When the removable portion is removed from the container, the container contents may be accessed. The peelable portion may be resealed onto the container at any point in the process.

    摘要: 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 tear portion that is torn through upon initial opening, thus indicating the package has been at least partially opened.

    摘要: The invention is directed to a polymeric film web, a carrier film, and a magnetic member. The carrier film comprises an inner polyethylene terephthalate layer and an outer plastomer layer. The magnetic member and the carrier film are layered onto the polymeric film web to form a closure member. The outer plastomer layer is adjacent the magnetic member and the carrier film extends beyond an upper edge and/or a lower edge of the magnetic member. The closure is heat sealed such that the seal at the interface of the first carrier film and the second carrier film is a peelable seal, the seal at the interface of the first film web and the first carrier film is a permanent seal, and the seal at the interface of the second film web and the second carrier film is a permanent seal.

    摘要: 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.
