Abstract: The present invention discloses a paperboard for packaging of liquid and frozen food, comprising a dispersion coating (2, 3) as the only barrier layer on its outside/print side. It has surprisingly been found that a dispersion coating comprising latex and pigment applied on the outside/print side of a paperboard for liquid and/or frozen food may serve as the only barrier against moisture arising from condensation.

Abstract: A method for reducing the surface oil absorption of cellulose based substrate is provided, in which a coating composition is applied to said substrate; and in which the coating composition comprises carboxymethyl cellulose (CMC) and/or a salt of carboxymethyl cellulose (CMC). A coated paperboard, and a laminate of the coated paperboard with a polymer layer is also provided. The coating composition provides improved surface oil absorption and improved adherence of an overlying polymer layer.
