Abstract: A flat film barrier laminate material for food packaging includes a core layer of paper or paperboard having a first side and a second side, a polymeric coating applied to the first side of the core layer and a food contacting layer disposed on the second side of the core layer. The food contacting barrier layer is formed from a plurality of series of layers of polymeric materials. Each series of layers includes a polyolefin layer, a tie layer, a polyamide resin layer, a tie layer and a polyolefin layer. The plurality is a whole number greater than one and the layers are applied to provide a weight ratio of materials in each series of 15:50 for the polyolefin layers, 5:50 for the tie layers and 10:50 for the polyamide resin layer.
