  • Publication number: 20130313260
    Abstract: A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.

  • Patent number: 8517201
    Abstract: Heat-sealable seal including a support bonded to an inner seal by a temporary adhesive is provided. The inner seal has a pull-tab which is folded back once on the surface of the inner seal in contact with the corresponding surface of the support. The inner seal includes a laminate having a reinforcing layer and a sheet of a conducting material, to the lower surface of which is applied a heat-sealing film. The temporary adhesive is applied to the whole surface of the inner seal once the pull-tab is folded back. The seal is characterized in that the laminate has over its entire thickness a notch from which the pull-tab emerges, and a fold line formed by the pull-tab once the pull-tab is folded back, the fold line having a shorter length than the length of the notch. Methods of producing the seal are also disclosed.

  • Publication number: 20130068768
    Abstract: Multi-layer films suitable as sealable or peelable sheet that can be used for closing foodstuff containers are described. These multi-layer films includes a polymeric substrate layer and a seal or a peel-seal layer. The multilayer composite film preferably includes four component layers, namely in order, a polymeric base layer for mechanical strength, a thin organic barrier layer, an ethylene polymer-based adhesive layer, and a heat seal layer including an ethylene copolymer, such as ethylene vinyl acetate copolymer. The film is useful as a peelable heat sealable lid for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals.

  • Publication number: 20130056486
    Abstract: Disclosed is a peel and attach container seal that includes an upper cover surface having two connecting portions over an open container aperture. A release film is removed prior to adhering the first and second connecting portions along opposing sides of the container aperture, whereafter the upper surface resealably covers the aperture by way of a pull tab along one end. The first connecting portion comprises a high strength adhesive that is not adapted to separate from the container outer surface or the upper cover surface. The second connecting portion includes a multi-layer connection between the cover surface and the container surface, allowing ready peeling and reattaching of the cover while a resealing, high strength adhesive layer is retained on the container surface. The cover is therefore operably removable from over the container aperture by separation of the second connection portion layers and peeling back over the first connection portion.

  • Patent number: 8308363
    Abstract: A resealable closure for packages is provided which has a package integrity feature. The closure includes a two-ply material having an inner film layer and an outer film layer, forming a top of container. The outer film layer has a sealing panel completely covering a first panel and a second panel of the inner film layer. The sealing panel is permanently attached to the first panel and is releasably affixed a portion of the inner film layer around the perimeter of the first panel to form an opening in the top when the sealing panel with affixed first panel is peeled back from the top. The sealing panel is resealable against the top to seal the opening when the sealing panel is moved back against the top. The package integrity feature comprises the second panel of the inner layer which separates from the sealing panel to indicate that the container has been previously opened.
