摘要: The invention relates to a method for the production of heat-sealable paper that forms barrier water vapour, in particular having vapour permeability at most 150 g/m²/24h measured according ASTM F1249 under so-called tropical conditions 38° C and 90% relative humidity, which least one coating layer comprising thermoplastic film-forming polymer is applied in-line on paper-making machine fibrous substrate.
