Abstract (en)
The present invention relates to a barrier-coated cellulose-based substrate (25a) and to a method of manufacturing such cellulose-based substrates, by dispersion coating of a ductile base layer pre-coating (12a) and subsequent dispersion coating of a gas barrier composition (13a) and/or vapour deposition coating of a barrier deposition coating (14a). The invention further relates to laminated packaging materials (20a) comprising the barrier-coated celluose-based substrate (10), in particular intended for liquid carton food packaging, and to liquid carton packaging containers comprising the laminated packaging material.
