    • A method for sterilizing packaging material, the packaging material being employed subsequent to its sterilization for the aseptic packaging of foodstuffs. The method includes the steps of (1) first subjecting the packaging material to ultrasonic vibrations through a liquid medium, and (2) then subjecting the packaging material to ultraviolet radiation. The bactericidal effect of steps (1) and (2) combined together as a sequence in the order recited is greater than if practiced in the reverse order. The process of this invention can be applied to a moving web of packaging material. The moving web, after its sterilization treatment, can be fed through known machinery for forming, filling, and sealing of aseptic packages for foodstuffs.
    • 一种用于消毒包装材料的方法,该包装材料在其消毒无菌包装食品之后被使用。 该方法包括以下步骤:(1)首先使包装材料通过液体介质进行超声波振动,和(2)然后对包装材料进行紫外线辐射。 步骤(1)和(2)以所列顺序组合在一起作为序列的杀菌效果大于如果以相反的顺序实施的。 本发明的方法可以应用于包装材料的移动网。 移动纤维网在灭菌处理后,可以通过用于食品无菌包装的成型,灌装和密封的已知机械进料。
