据美刊〔现代金属〕1991年第9期报道,现在一些弱碳酸盐饮料和很多不含碳酸盐的饮料都能用轻质铝饮料罐包装.在包装之前,将氮气溶解在饮料之中,在封罐之后,氮气从液体中释放出来,在罐内建立起内部压力,从而强化了罐容器.用氮强化饮料罐,可避免其他强化方法引入的塑料片,罐的头部也不必留有太大的空间,饮料的保鲜期也可延长,因为去掉了罐内残留的氧气. According to the American Journal of Modern Metals, No. 9, 1991, some weak carbonate beverages and many non-carbonate-containing beverages can now be packaged in lightweight aluminum beverage cans. Prior to packaging, nitrogen is dissolved in the beverage , Nitrogen is released from the liquid after it is sealed and internal pressure builds up in the tank thereby strengthening the tank container.It is also possible to strengthen beverage cans with nitrogen to avoid plastic sheets introduced by other intensive methods and without the need for the head of the cans There is too much space left, and the shelf life of the beverage can be extended as the residual oxygen in the tank is removed.
