真(zhen)空包(bao)裝機(ji)廠的(de)真空包裝(zhuang)機增(zeng)加充(chong)(chong)(chong)氣(qi)(qi)功能是(shi)有(you)兩種(zhong)(zhong)方(fang)式(shi)，一(yi)種(zhong)(zhong)是(shi)氣(qi)(qi)嘴直接伸(shen)到(dao)(dao)產(chan)品袋子(zi)里(li)(li)面(mian)進行充(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)(zhong)是(shi)把要(yao)(yao)(yao)(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)體先充(chong)(chong)(chong)滿(man)整個真空室，然后靠(kao)負壓(ya)(ya)差(cha)充(chong)(chong)(chong)滿(man)袋子(zi)。那究竟(jing)采用哪種(zhong)(zhong)方(fang)式(shi)充(chong)(chong)(chong)氣(qi)(qi)好呢(ni)，這里(li)(li)主要(yao)(yao)(yao)(yao)看(kan)客(ke)戶的(de)產(chan)品性質，單純來說肯定是(shi)直接沖到(dao)(dao)袋子(zi)里(li)(li)比較好，這樣置(zhi)換(huan)的(de)又純還能省(sheng)不(bu)少(shao)氣(qi)(qi)源(yuan)，但是(shi)大家一(yi)定要(yao)(yao)(yao)(yao)考慮好自己產(chan)品性質。如(ru)果產(chan)品是(shi)顆粒(li)，我們(men)可以采取起(qi)初一(yi)種(zhong)(zhong)方(fang)法直接讓充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋子(zi)里(li)(li)進行充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)產(chan)品是(shi)粉末狀的(de)就(jiu)不(bu)能用起(qi)初一(yi)種(zhong)(zhong)方(fang)法了，需要(yao)(yao)(yao)(yao)第二種(zhong)(zhong)在真空室充(chong)(chong)(chong)氣(qi)(qi)利用壓(ya)(ya)力差(cha)充(chong)(chong)(chong)滿(man)袋子(zi)。可是(shi)客(ke)戶又要(yao)(yao)(yao)(yao)要(yao)(yao)(yao)(yao)求(qiu)達到(dao)(dao)一(yi)定比例的(de)殘氧量，這就(jiu)很矛盾了。
