真空包裝機廠的真空包裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)功能(neng)(neng)是(shi)(shi)(shi)(shi)有兩種(zhong)方(fang)式(shi)(shi)，一(yi)種(zhong)是(shi)(shi)(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸到(dao)產(chan)品(pin)袋(dai)(dai)(dai)子里(li)面(mian)進行充(chong)(chong)氣(qi)(qi)的，另一(yi)種(zhong)是(shi)(shi)(shi)(shi)把要(yao)充(chong)(chong)的氣(qi)(qi)體先充(chong)(chong)滿整個真空室，然后靠負壓(ya)差充(chong)(chong)滿袋(dai)(dai)(dai)子。那究竟采用(yong)哪種(zhong)方(fang)式(shi)(shi)充(chong)(chong)氣(qi)(qi)好呢，這(zhe)里(li)主要(yao)看客戶的產(chan)品(pin)性質(zhi)，單純(chun)來說肯定是(shi)(shi)(shi)(shi)直(zhi)接沖到(dao)袋(dai)(dai)(dai)子里(li)比較好，這(zhe)樣置換(huan)的又(you)純(chun)還能(neng)(neng)省不少氣(qi)(qi)源，但(dan)(dan)是(shi)(shi)(shi)(shi)大家一(yi)定要(yao)考慮好自己(ji)產(chan)品(pin)性質(zhi)。如(ru)(ru)果(guo)產(chan)品(pin)是(shi)(shi)(shi)(shi)顆(ke)粒，我們(men)可以采取起初一(yi)種(zhong)方(fang)法直(zhi)接讓充(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)(dai)子里(li)進行充(chong)(chong)氣(qi)(qi)，但(dan)(dan)是(shi)(shi)(shi)(shi)如(ru)(ru)果(guo)你的產(chan)品(pin)是(shi)(shi)(shi)(shi)粉末狀的就不能(neng)(neng)用(yong)起初一(yi)種(zhong)方(fang)法了(le)，需(xu)要(yao)第(di)二種(zhong)在真空室充(chong)(chong)氣(qi)(qi)利(li)用(yong)壓(ya)力差充(chong)(chong)滿袋(dai)(dai)(dai)子。可是(shi)(shi)(shi)(shi)客戶又(you)要(yao)要(yao)求達到(dao)一(yi)定比例的殘氧量，這(zhe)就很(hen)矛盾了(le)。
