摘要: The present invention discloses a paperboard for packaging of liquid and frozen food, comprising a dispersion coating 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.
