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.
