Abstract

The disclosure relates to a method of producing a packaging laminate comprising layers of plastic and aluminium, in which method an aluminium-clad web of paper is coated with a first plastic layer which is extruded on the aluminium-clad side of the paper web, whereafter the thus plastic-coated paper web is coated with a second plastic layer which is extruded on the first plastic layer applied on the paper web. Increased adhesion between the extruded first plastic layer and the foil cladding of the paper web is achieved by extending the contact time between the warm, extruded first plastic layer and the foil cladding of the paper web and extruding the second plastic layer while the first plastic layer is still warm.
