Polyethylene laminates for use in flexible packaging materials

A laminate structure comprising:

• a print film comprising ethylene-based polymer;
• a sealant film laminated to the print film, the sealant film comprising at least 3 layers and having an overall thickness from 15 to 30 μm, where the sealant film comprises a middle layer, an outer layer, and an inner layer disposed between the print film and the middle layer, wherein
• the inner layer comprises an ethylene interpolymer having a density from 0.900 to 0.925 g/cc and a melt index (12) from 0.5 to 5 g/10 min, wherein 12 is measured according to ASTM D1238 at 190° C. and 2.16 kg load;
• and
• at least one of the inner layer, the middle layer, and the outer layer comprise 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 (I10/I2) that meets the following equation:
• I10/I2≥7.0−1.2×log (I2).
