真空(kong)包裝機廠的真空包裝機增加充(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)(zhong)方式(shi)，一(yi)(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴直接伸到產(chan)(chan)品(pin)袋子里面進行(xing)充(chong)(chong)氣(qi)(qi)的，另一(yi)(yi)種(zhong)(zhong)是(shi)把要充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿(man)整個真空室，然(ran)后靠(kao)負壓差(cha)(cha)充(chong)(chong)滿(man)袋子。那(nei)究竟采用(yong)(yong)哪種(zhong)(zhong)方式(shi)充(chong)(chong)氣(qi)(qi)好呢，這(zhe)里主(zhu)要看客(ke)戶(hu)的產(chan)(chan)品(pin)性質(zhi)，單純(chun)來說(shuo)肯定是(shi)直接沖到袋子里比較(jiao)好，這(zhe)樣置換的又(you)純(chun)還能(neng)省(sheng)不少氣(qi)(qi)源(yuan)，但是(shi)大家一(yi)(yi)定要考(kao)慮好自己產(chan)(chan)品(pin)性質(zhi)。如果產(chan)(chan)品(pin)是(shi)顆粒，我們(men)可(ke)以采取起初(chu)一(yi)(yi)種(zhong)(zhong)方法直接讓充(chong)(chong)氣(qi)(qi)嘴到袋子里進行(xing)充(chong)(chong)氣(qi)(qi)，但是(shi)如果你的產(chan)(chan)品(pin)是(shi)粉末(mo)狀的就不能(neng)用(yong)(yong)起初(chu)一(yi)(yi)種(zhong)(zhong)方法了(le)(le)，需(xu)要第(di)二種(zhong)(zhong)在真空室充(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓力差(cha)(cha)充(chong)(chong)滿(man)袋子。可(ke)是(shi)客(ke)戶(hu)又(you)要要求達到一(yi)(yi)定比例(li)的殘氧量，這(zhe)就很(hen)矛(mao)盾了(le)(le)。
