  • Recyclable laminated polyolefin-based film structures
    Patent number: 11987026
    Abstract: A recyclable, laminated polyolefin-based film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin-based films. The film structure has an energy cured coating layer or a two-part coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin-based polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin-based film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 150 or 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin-based film structure.
