真空包裝機廠的(de)真空(kong)(kong)包裝機增加充(chong)氣(qi)(qi)功能是(shi)有(you)兩種(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴直(zhi)接伸到產品(pin)袋(dai)子(zi)(zi)里面進(jin)行(xing)充(chong)氣(qi)(qi)的(de)，另(ling)一(yi)種(zhong)(zhong)是(shi)把要(yao)(yao)(yao)充(chong)的(de)氣(qi)(qi)體先(xian)充(chong)滿(man)整(zheng)個真空(kong)(kong)室，然后靠負壓(ya)差充(chong)滿(man)袋(dai)子(zi)(zi)。那究竟(jing)采(cai)用哪種(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)好呢，這里主(zhu)要(yao)(yao)(yao)看客戶的(de)產品(pin)性(xing)(xing)質(zhi)，單純來說肯定是(shi)直(zhi)接沖到袋(dai)子(zi)(zi)里比(bi)較好，這樣置換的(de)又(you)純還能省不少氣(qi)(qi)源，但(dan)是(shi)大家一(yi)定要(yao)(yao)(yao)考慮好自己(ji)產品(pin)性(xing)(xing)質(zhi)。如果產品(pin)是(shi)顆(ke)粒，我們(men)可以采(cai)取起初(chu)一(yi)種(zhong)(zhong)方(fang)法直(zhi)接讓充(chong)氣(qi)(qi)嘴到袋(dai)子(zi)(zi)里進(jin)行(xing)充(chong)氣(qi)(qi)，但(dan)是(shi)如果你(ni)的(de)產品(pin)是(shi)粉末狀(zhuang)的(de)就不能用起初(chu)一(yi)種(zhong)(zhong)方(fang)法了，需要(yao)(yao)(yao)第二種(zhong)(zhong)在(zai)真空(kong)(kong)室充(chong)氣(qi)(qi)利用壓(ya)力(li)差充(chong)滿(man)袋(dai)子(zi)(zi)。可是(shi)客戶又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達到一(yi)定比(bi)例的(de)殘氧量，這就很矛盾了。
