真空包(bao)裝(zhuang)機廠的(de)真空包裝機增加充(chong)(chong)(chong)氣(qi)功能(neng)是(shi)(shi)有兩種(zhong)(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)氣(qi)嘴(zui)(zui)直(zhi)接(jie)伸到(dao)(dao)產(chan)(chan)(chan)(chan)品(pin)(pin)袋(dai)(dai)子(zi)里面進行充(chong)(chong)(chong)氣(qi)的(de)，另一(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)把(ba)要充(chong)(chong)(chong)的(de)氣(qi)體先充(chong)(chong)(chong)滿(man)整個真空室，然后靠負壓(ya)差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。那究竟采用哪種(zhong)(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)好(hao)呢(ni)，這(zhe)里主要看客戶的(de)產(chan)(chan)(chan)(chan)品(pin)(pin)性質，單純(chun)來(lai)說肯定是(shi)(shi)直(zhi)接(jie)沖到(dao)(dao)袋(dai)(dai)子(zi)里比較(jiao)好(hao)，這(zhe)樣置換的(de)又(you)純(chun)還能(neng)省不(bu)(bu)少氣(qi)源(yuan)，但是(shi)(shi)大家一(yi)定要考慮好(hao)自己產(chan)(chan)(chan)(chan)品(pin)(pin)性質。如果(guo)(guo)產(chan)(chan)(chan)(chan)品(pin)(pin)是(shi)(shi)顆粒，我們(men)可(ke)以(yi)采取起(qi)初一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法直(zhi)接(jie)讓充(chong)(chong)(chong)氣(qi)嘴(zui)(zui)到(dao)(dao)袋(dai)(dai)子(zi)里進行充(chong)(chong)(chong)氣(qi)，但是(shi)(shi)如果(guo)(guo)你的(de)產(chan)(chan)(chan)(chan)品(pin)(pin)是(shi)(shi)粉末狀的(de)就不(bu)(bu)能(neng)用起(qi)初一(yi)種(zhong)(zhong)(zhong)(zhong)方(fang)法了，需(xu)要第二種(zhong)(zhong)(zhong)(zhong)在真空室充(chong)(chong)(chong)氣(qi)利用壓(ya)力差充(chong)(chong)(chong)滿(man)袋(dai)(dai)子(zi)。可(ke)是(shi)(shi)客戶又(you)要要求達到(dao)(dao)一(yi)定比例(li)的(de)殘氧量，這(zhe)就很(hen)矛盾(dun)了。
