    摘要: 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 (2) which has a middle layer (6) containing CTMP or other similar mechanical pulp, on its both sides outer layers (7) formed from sulfate pulp, against these on both sides of the board (2) talc-containing polymeric barrier layers (3), and on one side of the board a heat sealing layer (9) introduced onto the barrier layer (3).
