LASER INDUCED STRUCTURAL MODIFICATION OF PAPERBOARDS

摘要

A method for locally modifying a structure of a paperboard. A penetrating region (114) of the paperboard (110) is penetrated by laser radiation (102) such that moisture in the penetrating region (114) evaporates for locally modifying the structure of the penetrating region (114) e.g. by weakening the paperboard at the region and for deforming it there.
