Abstract
Disclosed are biaxially oriented, multilayered films, wherein said films may include a core layer comprising linear, low-density polyethylene, and the core layer is optionally cavitated. Said films may further include a first skin layer on a first side of the core layer, and a second skin layer on a second side of the core layer, wherein the first skin layer and the second skin layer comprise thin layers of linear, low-density polyethylene of a same or different type. Further, said films may include an aqueous-based primer on an outer surface of the second skin layer, wherein the outer surface faces away from the core layer. Further still, said films may include a sealant coating layer on the first skin layer and a barrier coating layer on the second skin layer, wherein the sealant coating layer and the barrier coating layer are aqueous-based.
