Today punch devices are used to provide holes in various kinds of materials. Within the packaging industry, such punch devices can be used to provide holes in a packaging material later forming individual packages. In liquid food packaging, such holes may typically be intended to be penetrated by a straw. The packaging material may be a carton-based material, i.e. the packaging material comprises a core layer of carton-based material being laminated with one or more polymer layers. These types of packaging material are well known, and the hole is provided in the carton-based layer prior to lamination. In this manner the hole will be covered by the polymer layers thereby sealing the hole efficiently while still allowing for a fairly easy penetration.
