The invention relates to coated board, a process for its manufacture, and containers and packaging formed therefrom. The board comprises at least one polymer-based coat preventing the transmission of liquids and gases, which coat is according to the invention made from a polymer dispersion to which talc particles are added so that talc will constitute 30-80% of the dry weight of the dried coat. The coating is applied onto the board during its manufacture as on-line coating. The board may be, for example, a multi-layer board ( ) which has a middle layer ( ) containing CTMP or other similar mechanical pulp, on its both sides outer layers ( ) formed from sulfate pulp, against these on both sides of the board ( ) talc-containing polymeric barrier layers ( ), and on one side of the board a heat sealing layer ( ) introduced onto the barrier layer ( ).
