The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.
