Definitions
- the present invention also aims at a method for producing a packaging paper, with which method it is possible to provide a paper with excellent mechanical properties and a smooth surface.
- the method according to the invention is carried out in such a way that the base material is creped in a Clupak system until an elongation at break in the machine direction according to ISO 1924-3:2005 of between 2.5% and 8.5% is achieved, and then to is dried to a maximum moisture content of 14% and the base paper is finally subjected to a calendering step, resulting in a packaging paper with a Bendtsen roughness according to ISO 8791-2:2013 between 200 ml/min and 600 ml/min, preferably 250 ml/min to 550 ml/min, particularly preferably 300 ml/min to 500 ml/min, a basis weight according to ISO 536:2019 between 60 g/m 2 and 150 g/m 2 and an air resistance according to ISO 5636-5:2013 (Gurley) of between 5 and 30 seconds and
- the paper is additionally subjected to a coating treatment, such as an extrusion coating with polyethylene (eg 4.0 g/m 2 ) or, after a pigmenting primer with kaolin, a dispersion coating (1.8 g/m 2 ).
- a coating treatment such as an extrusion coating with polyethylene (eg 4.0 g/m 2 ) or, after a pigmenting primer with kaolin, a dispersion coating (1.8 g/m 2 ).
- a coating treatment such as an extrusion coating with polyethylene (eg 4.0 g/m 2 ) or, after a pigmenting primer with kaolin, a dispersion coating (1.8 g/m 2 ).
- Such paper was printed with a multicolor print using a flexographic printing process.
- the colors showed a high level of brilliance and bleeding of the same could not be observed.
