A high barrier, multilayer laminate is disclosed that is suitable for forming packages that contain oxygen sensitive products. The laminate material comprises a first layer including biaxially oriented polyethylene terephthalate, a second layer of a high barrier oxide material disposed exterior to the first layer, and a third layer of an adhesive material disposed interior to the first layer and joining the first layer to a fourth coextruded multilayer material. The fourth coextruded multilayer material comprises from exterior to interior: i) a first layer of a polyethylene material, ii) an oxygen scavenging layer comprising a polyethylene and an oxygen scavenger material, wherein the oxygen scavenging layer is disposed interior to the first layer of the polyethylene material, and iii) a second layer of the polyethylene material disposed interior to the oxygen scavenging layer. A further laminate structure suitable for forming a package containing an oxygen sensitive product is also disclosed. The further laminate comprises a first layer comprising biaxially oriented polyethylene terephthalate, biaxially oriented polyamide, or biaxially oriented polypropylene, a second layer of a high barrier oxide material disposed interior to the first layer, and a third layer of an adhesive material disposed interior to the second layer and joining the second layer to a fourth layer of a polyethylene material. The third layer of adhesive material includes an oxygen scavenger material.
