真空包裝機廠的(de)(de)真空(kong)(kong)包裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)(qi)功能是有兩種(zhong)方(fang)(fang)式，一(yi)種(zhong)是氣(qi)(qi)(qi)嘴直接伸到產(chan)品(pin)袋子(zi)里(li)(li)面進行(xing)充(chong)(chong)氣(qi)(qi)(qi)的(de)(de)，另一(yi)種(zhong)是把要(yao)(yao)充(chong)(chong)的(de)(de)氣(qi)(qi)(qi)體(ti)先(xian)充(chong)(chong)滿整(zheng)個真空(kong)(kong)室(shi)，然后靠負壓(ya)差充(chong)(chong)滿袋子(zi)。那究竟采用哪種(zhong)方(fang)(fang)式充(chong)(chong)氣(qi)(qi)(qi)好呢，這(zhe)里(li)(li)主(zhu)要(yao)(yao)看客戶的(de)(de)產(chan)品(pin)性質，單純來(lai)說(shuo)肯定(ding)是直接沖到袋子(zi)里(li)(li)比(bi)較好，這(zhe)樣(yang)置換的(de)(de)又純還能省不(bu)少氣(qi)(qi)(qi)源，但是大家一(yi)定(ding)要(yao)(yao)考慮好自己產(chan)品(pin)性質。如果產(chan)品(pin)是顆粒，我們可以采取起初一(yi)種(zhong)方(fang)(fang)法直接讓充(chong)(chong)氣(qi)(qi)(qi)嘴到袋子(zi)里(li)(li)進行(xing)充(chong)(chong)氣(qi)(qi)(qi)，但是如果你(ni)的(de)(de)產(chan)品(pin)是粉末狀的(de)(de)就不(bu)能用起初一(yi)種(zhong)方(fang)(fang)法了，需(xu)要(yao)(yao)第(di)二種(zhong)在(zai)真空(kong)(kong)室(shi)充(chong)(chong)氣(qi)(qi)(qi)利用壓(ya)力差充(chong)(chong)滿袋子(zi)。可是客戶又要(yao)(yao)要(yao)(yao)求達到一(yi)定(ding)比(bi)例的(de)(de)殘氧量，這(zhe)就很(hen)矛盾了。
