Abstract (en)
[origin: WO2022269141A1] The invention relates to a sheet-like product, such as paper, board or the like, which comprises a substrate comprising cellulosic fibres and having a first large surface, wherein at least a first coating layer and a second coating layer are applied on the first large surface of the substrate by curtain coating to form a barrier coating. The second coating layer forms the surface of the sheet-like product. The first coating layer comprises a first polymer having a first crystallization degree and a first melting point, and the second coating layer comprises a second polymer having a second crystallization degree and a second melting point. The second crystallization degree and/or the second melting point is higher than the first crystallization degree and/or the first melting point of the first polymer.
