Abstract

A packaging laminate includes at least one material layer provided with magnetisable particles. A roller can be configured to apply crease line patterns on the packaging laminate while also applying magnetic fields for magnetising at least some of the magnetisable particles in the packaging laminate. A method of controlling working operations on a packaging laminate in a filling machine involves supplying a packaging laminate to a filling machine, wherein the packaging laminate includes at least one material layer comprising magnetizable particles, with at least some of the magnetizable particles being magnetized particles. The method also involves controlling working operations of the filling machine on the packaging laminate supplied to the filling machine by reading information provided by the magnetized particles.
