Abstract: Envelope seal strip are disclosed. An example envelope includes a flap that is rotatable about a hinge between an open position and a closed position of the envelope. The example envelope includes a first adhesive layer disposed on an inner surface of the flap and a sealing strip having a second adhesive layer. In the open position, the sealing strip is releasably coupled to the first adhesive layer via the second adhesive layer. To secure the flap in the closed position, the first adhesive layer and the second adhesive layer enable the sealing strip to decouple from the first adhesive layer, the hinge enables the flap to rotate about the hinge to cause the first adhesive layer to adhere to a second wall, and the second adhesive layer enables the sealing strip to adhere to the second wall and an outer surface of the flap.

Abstract: A sealing strip on a release layer is disclosed. The release layer can include an envelope with walls cooperatively enclosing a pocket with an opening. The envelope can include a closure flap pivotable to close the envelope. A first location of the envelope can include a sealing strip releasably adhered to the envelope (or a release layer on the envelope). This sealing strip can be removable from the first location and placeable in a second location overlapping the closure flap in the closed position and an adjacent portion of an envelope wall. The sealing strip can include an adhesive capable of adhering to the closure flap and adjacent portion of the second wall for securing the closure flap in the closed position. The sealing strip can include a removable grasping tab connected by a weakened area. The sealing strip can be provided on a release layer independent of an envelope.

Abstract: A method of producing an adhesive article including the steps of applying release coating compound(s) to a second side of a liner backing; applying an adhesive onto a first side of said coated liner backing; crosslinking said adhesive with E-Beam radiation applied through the second side of said liner backing; and winding said article into a roll.

Abstract: An adhesive article including a liner having a first side and a second side; and an adhesive having a first surface and a second surface, wherein the second surface of the adhesive contacts the first side of the liner, wherein the article has been exposed to E-Beam radiation through the second side of the liner, and wherein the article has been wound upon itself causing the second side of the liner to come into contact with the first surface of the adhesive, and wherein the second side of the liner to the first surface of the adhesive have a release value that is less than the release value of the first side of the liner to the second surface of the adhesive. A method of producing an adhesive article including the steps of applying release coating compound(s) to a second side of a liner backing; applying an adhesive onto a first side of said coated liner backing; crosslinking said adhesive with E-Beam radiation applied through the second side of said liner backing; and winding said article into a roll.

Abstract: The present application relates to a method and device for making a magnetically mountable substrate construction from a selected substrate for magnetic mounting to a structure including magnetizable material. The magnetically mountable substrate may be formed from a pressure sensitive adhesive magnetic sheet material which includes a flexible magnetic substrate having a first major surface and a second major surface, with a pressure sensitive adhesive layer adhering to the first major surface and a release layer, such as silicone release layer, adhering to the second major surface. The magnetic sheet may be provided in the form of continuous lengths wound in a roll with the release layer in contact with the pressure sensitive layer of an adjacent winding to facilitate unwinding without delamination.

Abstract: The invention is a tamper indicating device including a backing. The backing includes a first phase and a second phase. The backing is normally light transmissive, but a peeling force causes the backing to internally delamninate and become opaque. A first skin layer is fixed to the backing wherein the skin layer minimizes pre-destruction of the backing. A layer of adhesive is applied to the first skin layer, which can be affixed to a substrate.

Abstract: The present invention provides a release coated film, an adhesive tape comprising a release coated film, and processes for preparing the same. The fluoropolymer release layer comprises a graft copolymer of (i) a base polymer containing polymerized units derived from monomers having terminal olefinic double bonds, and (ii) a moiety comprising a fluoroaliphatic group. The film may be coextruded and may subsequently be oriented in at least one direction. Alternately, the release coating can be extrusion coated onto a backing and may be subsequently oriented if the backing is orientable. Adhesives may be coated onto the release coated films either before or after orientation, or they may be coextruded along with the release coating and/or backing.

Abstract: A tamper indicating tape for use with a closure or container. The tape comprises a film including phase separated polymers. Colored indicia are applied to opposing major surfaces of the film indicative of a condition that someone has tampered with the tape, e.g., tape removal and reattachment, or abrading. The film further bears a layer of adhesive thereon as a means for adhering the tape to a portion of a container or to a closure tape on a can lid. When the film of the tamper indicating tape is sufficiently split, one set of colored indicia is obscured and the other set of colored indicia is rendered perceptible. When the film is abraded to remove the perceptible set of colored indicia, the aforementioned obscured set of colored indicia is rendered perceptible.

Abstract: A tamper indicating film and tape for use with a package. The tape includes a delaminating film including pahse separated polymers. Indicia are applied to opposing major surfaces of the film indicative of different conditions of the tape. The film is adhesively applied to secure container parts together and enclose an opening in the container. When applied, only one of the indicia are perceptible. When the film is internally delaminated, obscuring one set of indicia and rendering the other set of indicia perceptible.
