  • Patent number: 8241746
    Abstract: A multilayer label comprising a polymeric film or cloth, e.g., a polyester film or a polyester woven cloth, having opposing facial surfaces, one facial surface of which is in intimate contact with a xylene-resistant, water-based topcoat and the other facial surface of which is in intimate contact with a pressure sensitive adhesive (PSA) if the other facial surface is a cloth, or a water-based, melted wax-resistant PSA if the other facial surface is a film.
    Type: Grant

  • Patent number: 8066432
    Abstract: Temperature-sensitive films that undergo an irreversible change in appearance when the films are heated to a threshold temperature are provided. Also provided are methods for indicating that an object in thermal contact with a temperature-sensitive film has reached a threshold temperature.

  • Publication number: 20110241187
    Abstract: A lead frame having a recessed die bond area. The lead frame has top and bottom surfaces and a first lead frame thickness defined as the distance between the top and bottom surfaces. The lead frame has a die bond area surface located within a reduced die bond area. A second thickness is defined as the distance between the die bond area surface and the bottom surface. The second lead frame thickness is less than the first lead frame thickness such that a semiconductor die disposed and attached to the die bond area surface has a reduced overall package thickness. A side wall formed between the die bond area surface and the top surface contains the adhesive material used to attach the die, which reduces adhesive bleeding and prevents wire bonding contamination.

  • Publication number: 20090029159
    Abstract: A high-heat, curl-resistant thin label is described, the label comprising: A. A film, e.g., polyester or polyimide film, having first and second facial surfaces; B. A crosslinked, printable coating, e.g., a phenoxy resin coating, in intimate contact with or near one of the facial surfaces of the film, the coating comprising either high surface area filler, e.g., silica or mica, or a thermoplastic elastomer, e.g., a polyether or polyester type of polyurethane; and C. A pressure-sensitive adhesive in intimate contact with or near the other facial surface of the film.

  • Patent number: 7081288
    Abstract: A heat resistant label stock comprised of an unsupported cast face sheet layer, an adhesive layer and a release liner characterized by a face sheet, an adhesive layer and a release liner. The label stock is generally tamper-evident in that removal destroys or damages the label. In certain embodiments the label stock is electrostatic dissipative.
