A non-foil paperboard laminate having excellent flavor barrier with superior heat sealability comprises paperboard having a layer of a heat-sealable, modified polyolefin extrusion coated onto its outer surface, a layer of low density polyethylene polymer extrusion coated onto its inner surface, and a product-contact barrier layer extrusion coated onto the inner layer of low density polyethylene polymer. The product-contact barrier layer may comprise one or more layers of a polymer having low permeability to flavor oils.
