Zusammenfassung:	This disclosure provides compositions and methods for an oriented film that may include a core layer consisting essentially of biaxially oriented linear low-density polyethylene, wherein the core layer has a first side and a second side. Further, the film may include a first sealant layer consisting essentially of biaxially oriented linear low-density polyethylene on the first side, and a second sealant layer consisting essentially of biaxially oriented linear low-density polyethylene on the first side, wherein the linear low-density polyethylenes in each of the film's layers may be of more than one type/grade, have the same or different densities, or both. Further still, the film is 30 μm or less in thickness, has a water-vapor transmission rate of ≤1 g/m2/d at 38° C. and 90% relative humidity, and has an oxygen transmission rate of ≤100 cm3/m2/d at 23° C. and 0% relative humidity.
