High puncture resistant and high toughness recyclable packaging film using polar polymer film

A high toughness, puncture resistant, recyclable, polyolefin-based film structure comprising:

• an outer layer having a first surface and a second surface opposite the first surface, the outer layer formed of one of (a) a machine direction oriented polyolefin-based film;
• and (b) a biaxially oriented polar polymer film;
• a middle layer having a first surface and a second surface opposite the first surface, the middle layer formed of the other one of (a) the machine direction oriented polyolefin-based film;
• and (b) the biaxially oriented polar polymer film;
• a first bonding interlayer bonding the second surface of the outer layer to the first surface of the middle layer;
• and
• an inner layer having a first surface and a second surface opposite the first surface, the first surface of inner layer bonded to the second surface middle layer, the inner layer comprising a polyolefin-based polymer, wherein at least the second surface of the inner layer is heat sealable, and wherein the second surface of the inner layer defines an innermost surface of the laminated film.
