Abstract

A method for sterilizing a liquid packaging sleeve-like blank having two open ends and made of a laminated material including a paper layer, includes the steps of sterilizing the blanks by circulating a circulating unit holding a large number of blanks in a sterilizing tank which contains a sterilizing agent, to dip the blanks in the sterilizing agent, and removing the sterilizing agent by circulating another circulating unit holding the large number of blanks in a hot air drying tank in which hot air is blown, to dry the blanks.
