ABSTRACT:
A method and apparatus for sterilizing packaging through irradiation with an excimer ultraviolet lamp which may be integrated on a packaging machine. The excimer ultraviolet lamp emits radiation at a substantially monochromatic wavelength within the ultraviolet band of the electromagnetic spectrum. The excimer ultraviolet lamp is composed of a quartz shell containing one of the following gaseous compounds: Ar.sub.2, Kr.sub.2, Xe.sub.2, ArCl, KrCl, KrF or XeCl. The KrCl gas excimer ultraviolet lamp which generates a wavelength of 222 nanometers is of particular interest for the present invention. In one embodiment, the lamp has a central aperture for flowing through a cooling fluid to remove heat from the lamp. If the excimer ultraviolet lamp is integrated on a form, fill and seal machine, the cooling fluid may be the desired contents filled into a container fabricated on the form, fill and seal machine. The materials sterilized by the present invention are fabricated into many different containers such as flexible pouches, stand-up pouches, parallelpiped containers and gable top cartons. The material may be subjected to a sterilant prior to irradiation by the excimer ultraviolet lamp. The sterilant may be hydrogen peroxide, peracid, ozone or the like. The concentration of the sterilant may have a range of between 1% to 55%.
