真(zhen)空包裝機廠的(de)真(zhen)空包裝機增加充(chong)(chong)(chong)氣(qi)(qi)功能(neng)是(shi)有兩種(zhong)方(fang)式，一(yi)種(zhong)是(shi)氣(qi)(qi)嘴直(zhi)(zhi)接伸到(dao)(dao)產(chan)(chan)品袋(dai)(dai)子(zi)(zi)(zi)里(li)面進行(xing)充(chong)(chong)(chong)氣(qi)(qi)的(de)，另一(yi)種(zhong)是(shi)把要(yao)(yao)(yao)充(chong)(chong)(chong)的(de)氣(qi)(qi)體(ti)先充(chong)(chong)(chong)滿整個(ge)真(zhen)空室(shi)，然后靠負壓(ya)差(cha)充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)(zi)。那(nei)究竟采(cai)用哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)好(hao)呢，這里(li)主(zhu)要(yao)(yao)(yao)看客(ke)戶的(de)產(chan)(chan)品性(xing)質(zhi)(zhi)，單(dan)純來說肯定(ding)是(shi)直(zhi)(zhi)接沖到(dao)(dao)袋(dai)(dai)子(zi)(zi)(zi)里(li)比(bi)較(jiao)好(hao)，這樣置(zhi)換(huan)的(de)又純還能(neng)省不少氣(qi)(qi)源，但是(shi)大家一(yi)定(ding)要(yao)(yao)(yao)考慮好(hao)自己產(chan)(chan)品性(xing)質(zhi)(zhi)。如(ru)果產(chan)(chan)品是(shi)顆粒，我們可(ke)以采(cai)取起(qi)初(chu)一(yi)種(zhong)方(fang)法直(zhi)(zhi)接讓(rang)充(chong)(chong)(chong)氣(qi)(qi)嘴到(dao)(dao)袋(dai)(dai)子(zi)(zi)(zi)里(li)進行(xing)充(chong)(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)產(chan)(chan)品是(shi)粉末狀(zhuang)的(de)就(jiu)不能(neng)用起(qi)初(chu)一(yi)種(zhong)方(fang)法了，需要(yao)(yao)(yao)第二種(zhong)在真(zhen)空室(shi)充(chong)(chong)(chong)氣(qi)(qi)利用壓(ya)力差(cha)充(chong)(chong)(chong)滿袋(dai)(dai)子(zi)(zi)(zi)。可(ke)是(shi)客(ke)戶又要(yao)(yao)(yao)要(yao)(yao)(yao)求達到(dao)(dao)一(yi)定(ding)比(bi)例的(de)殘氧(yang)量，這就(jiu)很矛(mao)盾了。
