Abstract: A device for sterilization in production of packages (8) is adapted for sterilization with a gaseous sterilizing agent which is kept in the gaseous phase throughout the sterilization process. The device comprises a heating zone (2), a sterilization zone (3) and a venting zone (4). It further comprises means for maintaining a higher pressure in the sterilization zone (3) than in the heating zone (2) and venting zone (4). A method of sterilizing packages (8) in production of the packages (8) is also disclosed. The packages (8) have an open end (11) and a closed end (12) A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process. A positive pressure is maintained in a sterilization zone (3) in which the sterilization is performed.

Abstract: A method of sterilizing packages in production of the packages, wherein the packages have an open end and a closed end. A gaseous sterilizing agent is used and kept in the gaseous phase throughout the sterilization process and an ambient temperature and a concentration of sterilizing agent in a sterilization zone where sterilization is performed are measured and used for controlling the amount of sterilizing agent introduced in the sterilization zone.

Abstract: A device (1) for sterilization in production of packages (8) is adapted for sterilization with a gaseous sterilizing agent kept in the gaseous phase throughout the sterilization process. The device (1) comprises a heating zone (2), a sterilization zone (3) and a venting zone (4). It further comprises an ambient temperature sensor (27) for sensing the ambient temperature outside the device (1), a concentration meter (29) for measuring the concentration of sterilizing agent in the sterilization zone (3) and a first control unit for controlling the amount of sterilizing agent introduced in the sterilization zone (3) based on the temperature measured by the ambient temperature sensor (27) and the concentration measured by the concentration meter (29). A method of sterilizing packages (8) in production of the packages (8) is also disclosed.

Abstract: The invention relates to a method for the sterilization of the inside layer of a packaging material, the packaging material being produced as a laminate with an inside layer of a transparent thermoplastic which is applied on a reflective material layer. The sterilizing energy includes high energy light flashes emitted from one or more flash units, the light flashes being caused to act on the inside of the packaging material for purposes of exterminating bacteria and microorganisms present on the surface. Because the light flashes emitted from the flash unit are reflected by the reflective layer, the surface layer of the layer will be influenced by both the direct and the reflecting photoenergy from the flash units, the sterilizing effect being thereby improved. Packaging material well-suited for sterilization according to the method is also disclosed.
