真(zhen)空包裝機廠的真(zhen)空(kong)(kong)包裝機增加(jia)充(chong)(chong)氣(qi)(qi)(qi)功能(neng)(neng)是(shi)(shi)(shi)有(you)兩種(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)是(shi)(shi)(shi)氣(qi)(qi)(qi)嘴直接伸到(dao)產品(pin)袋(dai)子(zi)里(li)(li)(li)面進行(xing)充(chong)(chong)氣(qi)(qi)(qi)的，另(ling)一(yi)種(zhong)(zhong)是(shi)(shi)(shi)把要(yao)充(chong)(chong)的氣(qi)(qi)(qi)體(ti)先充(chong)(chong)滿整個真(zhen)空(kong)(kong)室，然后靠(kao)負壓(ya)(ya)差充(chong)(chong)滿袋(dai)子(zi)。那究竟采用哪種(zhong)(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)(qi)好呢(ni)，這里(li)(li)(li)主要(yao)看客戶(hu)(hu)的產品(pin)性質，單(dan)純來說(shuo)肯定是(shi)(shi)(shi)直接沖到(dao)袋(dai)子(zi)里(li)(li)(li)比(bi)較好，這樣置(zhi)換的又純還(huan)能(neng)(neng)省不(bu)少氣(qi)(qi)(qi)源，但是(shi)(shi)(shi)大家一(yi)定要(yao)考慮好自己產品(pin)性質。如(ru)果(guo)產品(pin)是(shi)(shi)(shi)顆粒，我們可以采取(qu)起(qi)(qi)初(chu)(chu)一(yi)種(zhong)(zhong)方(fang)法(fa)直接讓充(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)子(zi)里(li)(li)(li)進行(xing)充(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)(shi)如(ru)果(guo)你的產品(pin)是(shi)(shi)(shi)粉(fen)末狀(zhuang)的就不(bu)能(neng)(neng)用起(qi)(qi)初(chu)(chu)一(yi)種(zhong)(zhong)方(fang)法(fa)了，需(xu)要(yao)第二種(zhong)(zhong)在真(zhen)空(kong)(kong)室充(chong)(chong)氣(qi)(qi)(qi)利(li)用壓(ya)(ya)力差充(chong)(chong)滿袋(dai)子(zi)。可是(shi)(shi)(shi)客戶(hu)(hu)又要(yao)要(yao)求達到(dao)一(yi)定比(bi)例的殘氧量，這就很矛(mao)盾了。
