Zusammenfassung:	A method and an apparatus for manufacturing a double bag (20) are disclosed. The method comprises placing an inner bag (30) in an outer bag (40) through an open top end (42), inserting a gas feeding tube (50) between through the open top end (42), feeding a head space (44) between the inner bag (30) and the outer bag (40) with an inert gas through the gas feeding tube (50), extracting the gas feeding tube (50), and sealing the top end (42). A gas box (80) surrounds the open top end (42) to reduce the risk of oxygen entering the head space (44). 公开了一种用于制造双袋(20)的方法和设备。该方法包括通过开放顶端(42)将内袋(30)放置在外袋(40)中，穿过开放顶端(42)之间插入气体供给管(50)，通过气体供给管(50)用惰性气体供给内袋(30)与外袋(40)之间的头部空间(44)，抽出气体供给管(50)，并且密封顶端(42)。气体箱室(80)环绕开放顶端(42)以降低氧气进入头部空间(44)的风险。
