- providing a bulk layer of paper or paperboard or other cellulose-based material;
- laminating one or more outside layers to the bulk layer, said outside layers intended to face the exterior of a packaging container formed by the packaging material,
- laminating one or more inside layers to the bulk layer, said inside layers intended to face the interior of a packaging container form by the packaging material,
