Zusammenfassung:	In one example embodiment, disclosed is a polyethylene film comprising a core layer comprising at least 85 wt. % high-density polyethylene. Further, the polyethylene film comprises a first tie layer on a first side of the core layer consisting essentially of: (i) at least about 50 wt. % high-density polyethylene; and (ii) from 5 wt. % through 40 wt. % of each of: (a) an olefin-block copolymer; and (b) low-density polyethylene polymer and/or ethylene-vinyl acetate polymer. Further still, the polyethylene film comprises a first skin layer on the first tie layer, wherein the first skin layer comprises a polyethylene-based polymer, silicone, and antiblock agent, wherein the polyethylene film is coextruded and oriented either monoaxially or biaxially. Yet further, the polyethylene film is adhered to face stock, which optionally excludes silicone.
