Laminated polyolefin-based film structure with coatings and printing
The granted patent US11987026B2 describes a laminated polyolefin-based film structure designed for enhanced performance and versatility. The structure consists of multiple film plies, with the first and third layers made from polyolefin films that contain at least 90% by weight of polyolefin homopolymers, copolymers, or terpolymers. These layers are coupled by an adhesive layer, while a printed layer is positioned between the first and third layers. The outermost surface of the film structure features a two-part coating composed of a cross-linkable binder, such as nitrocellulose, polyester, or polyurethane, and a cross-linking agent, typically an isocyanate compound. The patent also specifies that the coating composition can cure at room temperature, providing practical application benefits.
Further claims detail the thermal properties of the film structure, indicating that the melting temperature of the outermost surface is significantly higher—by at least 100 to 150 degrees Celsius—than that of the innermost surface. The patent allows for the inclusion of additional film plies, enhancing the structure's complexity and potential applications. Notably, the materials used in the film layers are recyclable, aligning with sustainability goals. The claims also cover various configurations for printed layers, which can be applied to different surfaces of the film structure. Overall, this patent presents a comprehensive approach to creating a durable, high-performance laminated film suitable for various industrial and consumer applications.
