Cartons for sterilised milk, cream or fruit juice are internally sterilised before filling by exposing them to a bactericidal radiation by electromagnetic waves or particles. The radiation source is directed with its window inside the carton to cover all internal surfaces. The carton is designed as to avoid any shadows on its inside.Process avoids the use of toxic disinfectants and ensures a long life of the packed liquids. The cartons need not be transported in refrigerated vehicles. Their filling operation can be readily automated.
