  • Patent number: 6248433
    Abstract: A multi-layer flexible insulation (I) comprises a series of layers which include a pair of closed-cell insulation sheets (10,12) made of multicellular plastic film (i.e. closed cell air bubbles or bubble-pack) and laminated on both sides of a thin white polyethylene film (14), a pair of aluminum foil layers or films (16,18) adhesively mounted on the outer surfaces of the bubble-pack insulation sheets (10,12), and a pair of thin clear polyester layers (20,22) provided on the outer surfaces of the aluminum layers. The aluminum layers (16,18) are vapor deposited on the polyester layers (20,22) and are assembled to the hot bubble-pack insulation sheets (10,12) while the latter are cooled. The bubble-pack sheets (10,12) are then adhered to the central polyethylene film (14) with a hot melt glue. If the polyester (20,22) is highly smooth, the aluminum (16,18) can be deposited thereon in a uniform state thereby providing a high reflectivity, low emissivity, laminate.

  • Patent number: 6248441
    Abstract: A method of enhancing the three-dimensional effect of a plastic part and the label used therewith is disclosed. A label for enhancing the three-dimensional visual effect which comprises a plastic core and/or, an insulating layer, and/or a heat-activated adhesive backing is disclosed. The label is aligned on the surface of a relieved mold. When plastic is forced against the back surface of the label, the label is stretched and forced into the relief along with the plastic. The label adheres to the plastic part by either a heat-activated adhesive backing or the core forms a melts/weld interface with the molded part creating a permanent bond between the label and the molded part.

  • Patent number: 6238802
    Abstract: For sealing and shielding purposes, a laminate is used, including a layer of ionomer plastics bonded to a metal sheet or a metal plate. The bonding is made without any addition of adhesive agents between the plastics layer and the metal surface by pressing, in a heated state, the plastics layer against a well cleaned surface. The metal should be such a kind, that its surface is oxidized when stored in air. A multi-layer laminate is used, where one metal layer provides a good electrical shielding and an outermost metal layer provides good mechanical strength. The plastics layer at the inner side of a laminate is in the same way bonded directly to margins of electrical connector terminals made of metal.

  • Patent number: 6235385
    Abstract: An electrically conductive adhesive tape used for electrical and electronic products to bond or fix an element to a support while maintaining an electrical conductibility between the element and support. The conductive adhesive tape has a structure including a resin film, a metal layer formed over one surface of the resin film by depositing a conductive metal over the surface of the resin film, and a conductive adhesive layer coated over the metal layer. The metal layer has a net-shaped structure. In some cases, the metal layer may have a planar structure. The conductive adhesive tape has a very small thickness by virtue of its metal layer deposited to a very small thickness. Accordingly, the conductive adhesive tape maintains a desired strength while exhibiting a high flexibility and a high bondability, thereby exhibiting a superior conductibility. In the case in which the metal layer has a net-shaped structure, the tape has a structure having spaces where the metal layer does not exist.

  • Patent number: 6224975
    Abstract: An opaque pressure sensitive adhesive (PSA) sheet or tape article, which comprises an anti-static coating on one side of a polymeric base film and an adhesive coating on the other side of the base film which can be opaque or transparent. If the base film is transparent, an opaque adhesive is coated onto the film to make it opaque. However, a clear adhesive can be coated onto the base film to make an opaque pressure sensitive adhesive tape if the base film itself is opaque. The total thickness of the pressure sensitive-tape ranges from about 0.4 mil to about 1.8 mil with a base film thickness no greater than about 1.4 mil. The pressure sensitive tape should have an opacity of greater than or equal to about 70%. The resistivity of the prepared sheet having an anti-static coating layer thereon should not be larger than about 1012&OHgr;/SQ.

  • Patent number: 6221198
    Abstract: Environmental stabilizing agents are stored in an adhesive adjoining, directly or indirectly, a film or membrane that requires protection from the environment. Such stabilizing agents include ultra-violet protectors and anti-oxidants. Migration of such environmental stabilizing agents from an adhesive to a film or membrane permits the use of new and different materials for such films and membranes because their method of manufacture no longer needs to accommodate the heat and processing sensitivities of the stabilizing agents.

  • Patent number: 6221485
    Abstract: A silicone release composition having a non-gloss, i.e., matte finished, surface and a linerless label incorporating the silicone release composition. The release composition includes a crosslinked silicone-based polymer having microparticles of a polymeric wax at least partially embedded therein. The polymeric wax may be polytetrafluoroethylene, polypropylene or other polyolefin, or a hydrocarbon-based wax. The microparticles of polymeric wax cause incidental light to scatter upon reflection, giving the release composition surface matte appearance. This makes the release composition particularly useful for linerless labels on which bar coded information will be printed. Also, a method for producing linerless label stock. The method includes mixing an uncured silicone material with microparticles of a polymeric wax. The mixture is coated onto a substrate and exposed to UV radiation to cure or crosslink the silicone around the microparticles of wax.
