真(zhen)空包(bao)裝(zhuang)機廠(chang)的(de)真空包(bao)裝機增加充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)功能(neng)是(shi)(shi)有兩種方(fang)(fang)式，一種是(shi)(shi)氣(qi)(qi)(qi)嘴直(zhi)(zhi)接伸到(dao)產(chan)品(pin)袋(dai)(dai)子里面進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)，另一種是(shi)(shi)把要充(chong)(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)體先充(chong)(chong)(chong)(chong)滿整個真空室，然后靠(kao)負壓差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子。那究竟采(cai)(cai)用哪種方(fang)(fang)式充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)好(hao)呢(ni)，這里主(zhu)要看客(ke)戶的(de)產(chan)品(pin)性(xing)質，單(dan)純來說肯定(ding)是(shi)(shi)直(zhi)(zhi)接沖到(dao)袋(dai)(dai)子里比(bi)較好(hao)，這樣置(zhi)換的(de)又(you)純還能(neng)省不(bu)少氣(qi)(qi)(qi)源，但是(shi)(shi)大家一定(ding)要考(kao)慮好(hao)自己(ji)產(chan)品(pin)性(xing)質。如果(guo)產(chan)品(pin)是(shi)(shi)顆(ke)粒，我們可以采(cai)(cai)取(qu)起初一種方(fang)(fang)法直(zhi)(zhi)接讓充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到(dao)袋(dai)(dai)子里進行(xing)充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)，但是(shi)(shi)如果(guo)你(ni)的(de)產(chan)品(pin)是(shi)(shi)粉末狀的(de)就不(bu)能(neng)用起初一種方(fang)(fang)法了，需(xu)要第二種在(zai)真空室充(chong)(chong)(chong)(chong)氣(qi)(qi)(qi)利用壓力差充(chong)(chong)(chong)(chong)滿袋(dai)(dai)子。可是(shi)(shi)客(ke)戶又(you)要要求達到(dao)一定(ding)比(bi)例的(de)殘氧量，這就很矛盾了。
