Abstract
The automatic filling and packaging of foodstuffs under aseptic to low-bacterial count conditions is accomplished by disinfecting a packaging material for at least one second by means of high-intensity ultraviolet radiation, generated by a high-current, low-pressure mercury discharge with a current density of more than 1 A/cm.sup.2 and a mercury pressure of 5 .times. 10.sup.-3 to 5 .times. 10.sup.-1 Torr, wherein the spectral radiation intensity of the 253.7 nm line of the ultraviolet radiation UV on the packaging material 1, 2, 3 is set to at least 0.05 W/cm.sup.2.
