真空包(bao)裝機廠的(de)(de)真(zhen)空(kong)包(bao)裝機增加(jia)充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)(shi)(shi)有兩種方(fang)式，一種是(shi)(shi)(shi)氣(qi)(qi)嘴直(zhi)接伸(shen)到產(chan)(chan)品(pin)袋(dai)子(zi)(zi)(zi)里面進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)(de)，另一種是(shi)(shi)(shi)把要(yao)充(chong)(chong)(chong)的(de)(de)氣(qi)(qi)體(ti)先(xian)充(chong)(chong)(chong)滿整個真(zhen)空(kong)室，然后靠負壓(ya)差充(chong)(chong)(chong)滿袋(dai)子(zi)(zi)(zi)。那究竟采用哪種方(fang)式充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這(zhe)里主要(yao)看客(ke)戶的(de)(de)產(chan)(chan)品(pin)性(xing)質(zhi)，單純(chun)(chun)來說肯定是(shi)(shi)(shi)直(zhi)接沖(chong)到袋(dai)子(zi)(zi)(zi)里比較好，這(zhe)樣置換的(de)(de)又(you)純(chun)(chun)還(huan)能省不少氣(qi)(qi)源，但是(shi)(shi)(shi)大家一定要(yao)考慮好自己產(chan)(chan)品(pin)性(xing)質(zhi)。如果(guo)產(chan)(chan)品(pin)是(shi)(shi)(shi)顆粒，我們可以采取起初一種方(fang)法直(zhi)接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)嘴到袋(dai)子(zi)(zi)(zi)里進(jin)行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)(shi)(shi)如果(guo)你的(de)(de)產(chan)(chan)品(pin)是(shi)(shi)(shi)粉末狀(zhuang)的(de)(de)就不能用起初一種方(fang)法了，需(xu)要(yao)第二種在(zai)真(zhen)空(kong)室充(chong)(chong)(chong)氣(qi)(qi)利用壓(ya)力差充(chong)(chong)(chong)滿袋(dai)子(zi)(zi)(zi)。可是(shi)(shi)(shi)客(ke)戶又(you)要(yao)要(yao)求達到一定比例的(de)(de)殘氧量，這(zhe)就很(hen)矛盾了。
