The object of the invention is a liquid packaging board (1), wherein the base board (3) is provided with at least one polymeric coating layer on both sides thereof to decrease the flavour scalping from a packaged liquid, such as citrus fruit juice. Inside the baseboard, there is a layer (6) of ethylene methyl acrylate copolymer either in a direct contact with the packaged liquid or coated with a thin layer of polyolefin. The invention also relates to a closed package for liquid food that is formed from the liquid packaging board (1) by folding and seaming, wherein the side that comes in contact with the food product, correspondingly, comprises an EMA layer and, possibly, a thin polyolefin layer on top of the same. The invention further comprises the use of EMA in decreasing the flavour scalping from the packaged liquid by the packaging material.
