The invention provides a method of cutting out an opening in a flat cardboard blank () that is for use in manufacturing a package, wherein a first portion () of the blank () and an ejector tape () that face each other are pressed together between a presser tool () and an activation tool () that face each other so as to cause the ejector tape () to stick exclusively on the first portion () of the blank (). The invention also provides an ejector tape for such a method. 110121113.
