  • Publication number: 20240101855
    Abstract: A coated article having recyclability properties including a combination of: (a) at least one polyolefin polymer article; and (b) a coating layer of a waterborne acrylic-based matte coating composition having a recyclability property, wherein the recyclability property of the waterborne acrylic-based matte coating composition is such that when the article with the waterborne acrylic-based matte coating composition is reprocessed, the article with the waterborne acrylic-based matte coating composition exhibits at least less than a 30% decreased change in performance compared to a control article without the waterborne acrylic-based matte coating composition; wherein both the control article and the article with the waterborne acrylic-based matte coating composition are both reprocessed the same way; a recyclable coated film structure including at least: (a) at least one first polymer film layer; and (b) at least one coating layer of the above recyclable waterborne acrylic-based matte coating composition; and a

  • Publication number: 20240001656
    Abstract: An article having recyclability properties including a combination of: (a) at least one polyolefin polymer; and (b) a waterborne adhesive composition having a recyclability property, wherein the recyclability property of the waterborne adhesive composition is such that when the article with the waterborne adhesive composition is reprocessed, the article with the waterborne adhesive composition exhibits less than a 40% decreased change in performance compared to a control article without the waterborne adhesive composition that is reprocessed the same way as the article with the waterborne adhesive composition; a recyclable laminate structure including (a) at least one first polymer film layer; and (?) at least one layer of the above waterborne laminating adhesive composition; and a process for manufacturing the above recyclable laminate structure.
