真(zhen)空包裝(zhuang)機廠的(de)(de)真空(kong)包裝機增加充(chong)(chong)氣(qi)功能(neng)(neng)是(shi)有兩種(zhong)方式，一(yi)種(zhong)是(shi)氣(qi)嘴直(zhi)(zhi)接(jie)伸到產(chan)(chan)品(pin)袋(dai)子里面進行充(chong)(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)是(shi)把要(yao)充(chong)(chong)的(de)(de)氣(qi)體先充(chong)(chong)滿(man)(man)整個(ge)真空(kong)室(shi)(shi)，然后靠負壓差充(chong)(chong)滿(man)(man)袋(dai)子。那究竟采用(yong)哪種(zhong)方式充(chong)(chong)氣(qi)好(hao)呢，這(zhe)里主要(yao)看(kan)客戶(hu)的(de)(de)產(chan)(chan)品(pin)性質(zhi)，單純(chun)來說肯(ken)定(ding)(ding)是(shi)直(zhi)(zhi)接(jie)沖(chong)到袋(dai)子里比(bi)較好(hao)，這(zhe)樣置(zhi)換的(de)(de)又純(chun)還能(neng)(neng)省不少氣(qi)源，但(dan)是(shi)大家一(yi)定(ding)(ding)要(yao)考(kao)慮好(hao)自(zi)己產(chan)(chan)品(pin)性質(zhi)。如果產(chan)(chan)品(pin)是(shi)顆粒，我們可以采取起初(chu)一(yi)種(zhong)方法直(zhi)(zhi)接(jie)讓(rang)充(chong)(chong)氣(qi)嘴到袋(dai)子里進行充(chong)(chong)氣(qi)，但(dan)是(shi)如果你的(de)(de)產(chan)(chan)品(pin)是(shi)粉末狀的(de)(de)就不能(neng)(neng)用(yong)起初(chu)一(yi)種(zhong)方法了，需要(yao)第二種(zhong)在(zai)真空(kong)室(shi)(shi)充(chong)(chong)氣(qi)利用(yong)壓力差充(chong)(chong)滿(man)(man)袋(dai)子。可是(shi)客戶(hu)又要(yao)要(yao)求達到一(yi)定(ding)(ding)比(bi)例的(de)(de)殘(can)氧量，這(zhe)就很矛盾(dun)了。
