真(zhen)空包裝機廠的(de)(de)真空包裝機增加(jia)充(chong)(chong)氣(qi)(qi)功能(neng)(neng)(neng)是有兩種(zhong)方式(shi)，一種(zhong)是氣(qi)(qi)嘴(zui)直(zhi)接伸到(dao)(dao)產(chan)(chan)品(pin)袋子(zi)里(li)面進行(xing)充(chong)(chong)氣(qi)(qi)的(de)(de)，另一種(zhong)是把(ba)要(yao)(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)體先充(chong)(chong)滿(man)(man)整個真空室，然(ran)后靠負(fu)壓(ya)(ya)差充(chong)(chong)滿(man)(man)袋子(zi)。那究竟采用(yong)哪種(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好呢，這里(li)主要(yao)(yao)看客(ke)戶的(de)(de)產(chan)(chan)品(pin)性質，單(dan)純(chun)來說肯定是直(zhi)接沖到(dao)(dao)袋子(zi)里(li)比較好，這樣置換的(de)(de)又(you)純(chun)還能(neng)(neng)(neng)省不(bu)少氣(qi)(qi)源，但是大家(jia)一定要(yao)(yao)考慮好自己產(chan)(chan)品(pin)性質。如果產(chan)(chan)品(pin)是顆(ke)粒，我們(men)可(ke)以采取起初一種(zhong)方法(fa)直(zhi)接讓充(chong)(chong)氣(qi)(qi)嘴(zui)到(dao)(dao)袋子(zi)里(li)進行(xing)充(chong)(chong)氣(qi)(qi)，但是如果你的(de)(de)產(chan)(chan)品(pin)是粉末狀的(de)(de)就(jiu)不(bu)能(neng)(neng)(neng)用(yong)起初一種(zhong)方法(fa)了(le)，需要(yao)(yao)第(di)二(er)種(zhong)在(zai)真空室充(chong)(chong)氣(qi)(qi)利(li)用(yong)壓(ya)(ya)力差充(chong)(chong)滿(man)(man)袋子(zi)。可(ke)是客(ke)戶又(you)要(yao)(yao)要(yao)(yao)求達到(dao)(dao)一定比例的(de)(de)殘氧量，這就(jiu)很矛盾(dun)了(le)。
