A recyclable, laminated polyolefin film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin 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 layers. In certain embodiments, the outermost surface of the laminated polyolefin 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 film structure.

Recyclable laminated polyolefin-based film structures

A method of forming a flexible packaging film includes providing a first web including a polymer sealant layer, the first web having a first major surface and a second major surface opposite the first major surface. A second web including a polymer outer layer is provided, the second web having a third major surface and a fourth major surface opposite the third major surface. An adhesive layer is applied to the second major surface and the first web is laminated to the third major surface. Prior to laminating the first web to the second web, one or more slits are formed in the second web.
