Blank for forming a container

A method of printing a blank for forming a container, comprising the steps of:

• providing a blank having first and second opposite surfaces, an unfolded condition and a folded condition, when the blank is in the unfolded condition the first surface has a panel disposed between a first attachment region and a second attachment region, the first and second attachment regions for receiving an adhesive, when the blank is in the folded condition each of the first and second attachment regions face the second surface of a corresponding attachment region such that the panel of the first surface forms an outer surface of the container and the first and second attachment regions of the first surface are provided inside the outer surface of the container, wherein the first blank surface has a surface tension in a predetermined range between about 34 dynes/cm and about 60 dynes/cm, suitable for application of the adhesive;
• applying a main substance onto at least the first blank surface to obtain at least one printed surface, the main substance being an ink, a varnish, a lacquer, or a combination thereof;
• and
• treating the first and second attachment regions of the first blank surface to maintain a surface tension in the predetermined range by applying an auxiliary substance comprising an ink, a varnish, a lacquer or a combination thereof to an external surface of the first and second attachment regions of the first blank surface,
• applying an adhesive to the first and second attachment regions of the first blank surface after the step of treating the first and second attachment regions of the first blank surface.
