Abstract: It provides laminates and articles formed from such laminates. In one aspect, a laminate comprises (a) a biaxially oriented polyethylene (BOPE) film comprising a polyethylene composition, wherein the polyethylene composition has a density of 0.910 to 0.940 g/cm3, an MWHDF>95 greater than 135 kg/mol and an IHDF >95 greater than 42 kg/mol, wherein the BOPE film comprises at least 50 weight percent of the polyethylene composition based on the weight of the BOPE film; (b) a barrier adhesive layer comprising polyurethane; and (c) a polyethylene film, wherein the barrier adhesive layer adheres the BOPE film to the polyethylene film and wherein the laminate has an oxygen gas transmission rate of 700 cc/[m2-day] or less when measured according to ASTM D3985-05.
