Abstract
Embodiments of multilayer films and laminate structures for flexible packaging comprise a multilayer polyolefin film comprising at least 3 layers. The multilayer polyolefin film comprises a first surface layer comprising: a first composition comprising at least one ethylene based polymer, wherein the first composition comprises a Molecular Weighted Comonomer Distribution Index (MWCDI) value greater than 0.9, and a melt index ratio (I/I) that meets the following equation: I/I≥7.0−1.2×log (I). The first surface layer also comprises a second composition comprising an ethylene based polymer having a density from 0.890 to 0.925 g/cc and a melt index (I) from 0.2 to 2.0 g/10 min. The multilayer polyolefin film also comprises a first intermediate layer comprising the first composition.
