  • Patent number: 9327418
    Abstract: An adhesive film includes a film-like adhesive layer and a pair of separators sandwiching the adhesive layer. The outer edges of both separators extend outward beyond the outer edge of the adhesive layer, and a blade is used to form a notch on the adhesive layer side of the heavy release separator, along the outer edge of the adhesive layer. The thickness of the heavy release separator is between 50 ?m and 200 ?m, the average notch depth is between 5 ?m and 45 ?m and the standard deviation for the notch depth is no greater than 15 ?m. Specifying the notch depth allows complete cutting of the adhesive layer with the blade, while also limiting release problems between the heavy release separator and the adhesive layer.

  • Patent number: 9108770
    Abstract: A re-sealable package and method which includes roll stock, a pressure sensitive label and a release member. The re-sealable package includes an outer layer laminated to an inner sealant layer. The pressure sensitive label has a first preselected shape and includes a pressure sensitive adhesive on one side. The side having the pressure sensitive layer is adhered to the inner sealant layer of the roll stock. The release member is formed in the outer layer, the release member having a second preselected shape which is smaller than the first preselected shape of the pressure sensitive label. As the release member is lifted from the pressure sensitive label, an area of the pressure sensitive adhesive is exposed to allow portions of the package to be removably adhered to the area of pressure sensitive adhesive.

  • Patent number: 8859068
    Abstract: An adhesive stack comprises a shear layer positioned between two adhesive layers. The shear layer, comprised of a weak adhesive sub-layer positioned between substrate sub-layers, is designed to fail upon application of a deliberate and appropriate shear force and before the failure of the adhesive layers. The adhesive sub-layer defines a width and/or length less than a width and/or length of another layer or sub-layer of the adhesive stack. The adhesive stack aids in securing components within an electronic device to prevent movement of the component when the device is dropped, hit, or bumped. The adhesive stack may occupy minimal space within the device, and reduce the cost of securing the component within the device's interior. The adhesive stack may allow for replacement of the component by an authorized person applying an appropriate and deliberate force. The adhesive stack may aid in identifying components replaced by an unauthorized person.

  • Publication number: 20140048438
    Abstract: The present subject matter provides a layered article for sealing an opening in a package for a high alcohol content product. The layered article has a facestock, a reclosure adhesive, a machine direction oriented film, and a sealing adhesive. The sealing adhesive provides a good long-term seal for the package that is resistant to degradation from alcohol. The machine direction oriented film provides an alcohol barrier between the product and the reclosure adhesive. Upon opening, the film tears clean and straight in the machine direction to allow a portion of the film to stay in contact with the package and another portion of the film to be pulled from the package to expose the opening. The reclosure adhesive provides resealing capabilities for the layered article after the initial opening of the package. The clean straight tear also provides a tamper evident feature for the package.

  • Patent number: 7673909
    Abstract: A label intended to be applied to an article, and in particular to an item of cosmetic product packaging. The label includes a substrate having a first face which is covered, at least in part, by a first printing. A second face of the substrate is intended to be adhesive-bonded to the article. At least one first zone of the second face is covered by a first adhesive layer intended to hold the label in place on the article permanently. At least one second zone of the second face is covered by a second adhesive layer, different from the first one, with the second adhesive layer being such that the second zone is able to be unstuck from the article. The substrate also includes a second printing arranged so that, when the article is not transparent, the second printing is visible only when the second zone is unstuck from the article.

  • Patent number: 7294380
    Abstract: Clear and opaque polymeric film structures for providing clear and opaque labels that are removable, respectively. The film structure includes a core layer and first skin layer, wherein the first skin layer contains a polymeric matrix of a material that allows a label, which has been produced from the film structure and applied onto a container or product, to be removed from the container or product by the solution employed in a process for re-using the container. The first skin layer is co-extruded along with the remainder of the layers of the film structure, or the first skin layer is deposited on the film structure as an emulsion or extrusion coating. The first skin layer can be contacted with a water-based adhesive to affix the label onto a particular product or product container. Labels produced from the film structure exhibit a desirable combination of excellent initial adhesion strength, moisture resistance and delaminatability, as well as excellent removability.
