A direct thermal chemistry layer can be deposited directly onto a top surface of the face stock or alternatively a pre-print color layer can be depositing directly onto the top surface of the face stock and the direct thermal chemistry layer can be deposited/located onto the free side of the pre-print layer. The flexible vinyl layer can be adhered to a bottom side of the face stock via an adhesive tie-layer sandwiched between the bottom side of the face stock and the flexible vinyl layer. If desired, an anti-cling layer can also be incorporated into the identification devices.

  • Publication number: 20130209818
    Abstract: A multilayer light reflective self assembly film or coating which reflects light of a desired wavelength is obtained by blending block copolymer fractions of different molecular weight. The colour of light reflected by the film or coating depends on the relative amounts of the block copolymers in the blend. Thus, the colour of the reflected light is selectable by varying the relative amounts of the block copolymers in the blend. The polymers may be cross-linked by means of a suitable cross-linking agent. Applications of the film or coating include anti-counterfeiting devices.

  • Publication number: 20130199700
    Abstract: A label assembly for application to heat shrink containers and materials is described. The label assembly is adhered to the heat shrink material prior to heat shrinking that material. During heat shrinking of the container or material, the label assembly adapts to and accommodates dimensional changes and stresses in the container or material. After shrinking, the label assembly remains adhered to the container or material and is free of wrinkles or other undesirable defects.

  • Publication number: 20130143053
    Abstract: A moisture vapor and oxygen transmission resistant flexible film has a polymeric base layer and a barrier layer of discrete particles of a first organic polymer dispersed throughout a matrix of a second organic polymer. Preferably, the first and second polymers are water insoluble and water soluble, respectively. The barrier layer is formed by depositing onto the base layer a coating composition of finely divided insoluble organic polymer particles suspended in an aqueous solution of the water soluble organic polymer, a crosslinking agent and surfactant. The coating composition is heated to crosslink the barrier layer polymers and evaporate solvent to provide a barrier film suitable for packaging applications. Optionally, the film can be metalized to increase barrier properties.
