  • Packaging articles and lamination films
    Patent number: 8808844
    Abstract: The present application relates to films and packaging articles having films bonded thereto. Also provided are methods of making and applying multilayered films. Exemplary polymeric films include a first layer adjacent the metal sheet having one or more polyester materials and a plurality of metal flakes disposed therein, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers. Other exemplary films include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers and an opacifying amount of titanium dioxide filler. Yet other exemplary films comprise an oxygen-scavenging material and include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers.
    Type: Grant

  • Method of monitoring extent of cure
    Patent number: 7043326
    Abstract: Method of measuring extent of cure of a coating comprising operating a metal-containing substrate coating operation to provide a coated metal-containing substrate; positioning an investigative apparatus near the coated metal-containing substrate; and operating the investigative apparatus to obtain an extent of cure reading, the reading corresponding to an area on the coated metal-containing substrate.
