PROBLEM TO BE SOLVED: To solve the problems of residue of chemicals, cleansing and waste liquid treatment although aseptic packaging by which foods and beverages can be distributed at normal temperature is performed for the treatment of a container before filling by spraying of sterilizing chemicals and cleansing by the sterilizing chemicals, and the problem that electron beams transmitting a packaging material from an external surface and high voltage electron beams having transmitting power are not popular yet due to inconvenience of an operation and a device.SOLUTION: Low energy electron beams of 100 kV or less being convenient for electron beams are used. A thin film transmitting electron beams whose transmission power is little is used and, at first, irradiated with the electron beams from a rear surface, an internal surface is sterilized and filling is performed. An outer layer member is attached to the thin film and a package having a strength suitable for distribution and being aseptic packaging is obtained.
