Abstract
A method for providing crease lines to a packaging material having a bulk layer is provided. The method comprises arranging the material to be creased between an elastic anvil and a pressing tool having at least one protrusive ridge facing the anvil, and pressing the ridge towards the anvil such that the packaging material will be subject to an imprint, whereby the width of the imprint is continuously increasing as the ridge is pressed against the anvil.
