Examples of a laminated structure and a flexible packaging material incorporating the same include: a first film including biaxially oriented polyethylene terephthalate (BOPET); and laminated to the first film and including The second film of the co-extruded film, wherein the second film includes a polyamide layer and a polyolefin layer, and the polyolefin layer includes a first composition. The first composition includes at least one ethylene-based polymer, wherein the first composition includes a Molecular Weighted Comonomer Distribution Index (MWCDI) greater than 0.9, and a melting index that conforms to the following equation Ratio (I 10 / I 2 ): I 10 / I 2 ≥ 7.0-1.2 × log (I 2 ). |
