Abstract

A pressure roller (300) of a roll-fed food packaging machine (100) for applying pressure along a longitudinal sealing section on an inside of a tube (112) of a laminate carton-based packaging material (104) is disclosed. The pressure roller (300) comprises a roller body (302) made of an elastically-deformable material, wherein an outer surface (304) of the roller body (302) is provided with an adhesion-reducing coating that is a ceramic nanocoating, i.e. a coating composed of ceramic particles in the order of nanometres. Such a coating helps reduce the risk of delamination of the packaging material. A roller arrangement (210), a longitudinal sealing device (110), a roll-fed packaging machine (100) as well as a method for producing the pressure roller (300) are also disclosed.
