真空(kong)包裝機廠的真空包裝機增(zeng)加(jia)充(chong)(chong)(chong)氣(qi)功(gong)能(neng)(neng)(neng)是(shi)有兩種(zhong)方式，一(yi)種(zhong)是(shi)氣(qi)嘴直(zhi)接(jie)伸到(dao)產(chan)品袋(dai)子(zi)里(li)面進行(xing)充(chong)(chong)(chong)氣(qi)的，另一(yi)種(zhong)是(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)的氣(qi)體先充(chong)(chong)(chong)滿(man)整個(ge)真空室(shi)，然后靠負壓差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。那究竟采用(yong)哪種(zhong)方式充(chong)(chong)(chong)氣(qi)好呢，這(zhe)里(li)主要(yao)(yao)(yao)看客(ke)戶(hu)的產(chan)品性質，單純(chun)(chun)來說肯定(ding)是(shi)直(zhi)接(jie)沖到(dao)袋(dai)子(zi)里(li)比較好，這(zhe)樣置換的又純(chun)(chun)還能(neng)(neng)(neng)省不少氣(qi)源(yuan)，但(dan)是(shi)大家(jia)一(yi)定(ding)要(yao)(yao)(yao)考慮好自己產(chan)品性質。如果(guo)產(chan)品是(shi)顆粒(li)，我們(men)可以采取起(qi)初一(yi)種(zhong)方法直(zhi)接(jie)讓(rang)充(chong)(chong)(chong)氣(qi)嘴到(dao)袋(dai)子(zi)里(li)進行(xing)充(chong)(chong)(chong)氣(qi)，但(dan)是(shi)如果(guo)你的產(chan)品是(shi)粉末狀的就不能(neng)(neng)(neng)用(yong)起(qi)初一(yi)種(zhong)方法了，需要(yao)(yao)(yao)第二種(zhong)在真空室(shi)充(chong)(chong)(chong)氣(qi)利用(yong)壓力差充(chong)(chong)(chong)滿(man)袋(dai)子(zi)。可是(shi)客(ke)戶(hu)又要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)一(yi)定(ding)比例的殘氧量，這(zhe)就很矛盾(dun)了。
