An uncoated paperboard for packages composed of one or more layers with a top layer of bleached kraft pulp having a gloss value of 15-50% measured according to Tappi T480, a minimal gloss variation (a coefficient of variation in the wavelength regions 3-30 mm of less than 5%), and a surface roughness (PPS-10) of 2-5 mumm measured according to ISO 8791-4, wherein the paperboard has a density in the range of 700 to 850 kg/m3 and is hydrophobic from a sizing agent treatment of each layer, is described. A package comprising the paperboard is suitable for co-sterilization of the package and its contents.
