真空包(bao)裝機廠的(de)(de)(de)真空包(bao)裝機增(zeng)加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)有兩(liang)種方(fang)式，一種是(shi)(shi)氣(qi)(qi)嘴直接(jie)伸(shen)到(dao)產品(pin)(pin)袋(dai)子里(li)面進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一種是(shi)(shi)把(ba)要(yao)(yao)充(chong)(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先(xian)充(chong)(chong)(chong)滿(man)整(zheng)個真空室，然后靠負壓差充(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采用哪種方(fang)式充(chong)(chong)(chong)氣(qi)(qi)好呢，這里(li)主要(yao)(yao)看客戶(hu)的(de)(de)(de)產品(pin)(pin)性(xing)質(zhi)，單(dan)純來說肯定是(shi)(shi)直接(jie)沖(chong)到(dao)袋(dai)子里(li)比較好，這樣置換(huan)的(de)(de)(de)又純還能省不少氣(qi)(qi)源，但是(shi)(shi)大家(jia)一定要(yao)(yao)考(kao)慮好自己產品(pin)(pin)性(xing)質(zhi)。如果(guo)產品(pin)(pin)是(shi)(shi)顆(ke)粒，我(wo)們(men)可以采取起初一種方(fang)法直接(jie)讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)子里(li)進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)如果(guo)你(ni)的(de)(de)(de)產品(pin)(pin)是(shi)(shi)粉末(mo)狀的(de)(de)(de)就(jiu)不能用起初一種方(fang)法了，需要(yao)(yao)第二種在真空室充(chong)(chong)(chong)氣(qi)(qi)利用壓力(li)差充(chong)(chong)(chong)滿(man)袋(dai)子。可是(shi)(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達到(dao)一定比例(li)的(de)(de)(de)殘氧量，這就(jiu)很矛盾了。
