The invention refers to a method to produce a packaging material comprising the steps of; treating at least one surface of a paperboard substrate with a binder and with a metal salt, printing at least a part of said treated surface with ink, and applying at least one polymer layer on said printed surface. The packaging material produced in accordance with the invention shows good printability and simultaneously good adhesion of the applied polymer layer.

A coating composition is described that can be completely biodegradable and well suited for use in laminating films to substrates. The coating composition contains a biodegradable polymer, such as a polyvinyl alcohol polymer. The coating composition can be applied to a biodegradable film and then adhered to a substrate, such as a paper substrate.
