Recyclable, paper-based composite film structures comprise a first ply comprising a paper substrate having a first major surface configured to face away from a packaged product. A second ply comprises a heat sealable polymer layer having a first major surface configured to face toward the paper substrate second major surface. The second major surface of the heat sealable polymer layer forms an innermost surface of the film structure. In some embodiments, a barrier layer is disposed on the first or second major surface of the paper substrate and an adhesion promotor is disposed intermediate the paper substrate and the heat sealable polymer layer. In alternative embodiments a barrier layer is disposed on the first major surface of the heat sealable polymer layer and the first and second plies are adhesively laminated. In embodiments, an adhesion promotor is disposed intermediate the paper substrate and the heat sealable polymer layer.
