真(zhen)空(kong)包裝機廠的(de)(de)(de)真空包裝機增(zeng)加充(chong)(chong)氣(qi)(qi)功(gong)能(neng)是有(you)兩種(zhong)方式，一(yi)種(zhong)是氣(qi)(qi)嘴直(zhi)接(jie)伸到(dao)產(chan)品(pin)袋(dai)(dai)子里(li)面(mian)進行充(chong)(chong)氣(qi)(qi)的(de)(de)(de)，另一(yi)種(zhong)是把(ba)要(yao)(yao)充(chong)(chong)的(de)(de)(de)氣(qi)(qi)體先(xian)充(chong)(chong)滿整個真空室(shi)，然后靠負壓(ya)差充(chong)(chong)滿袋(dai)(dai)子。那究竟采用(yong)(yong)哪種(zhong)方式充(chong)(chong)氣(qi)(qi)好呢，這里(li)主要(yao)(yao)看客戶(hu)的(de)(de)(de)產(chan)品(pin)性(xing)質，單(dan)純來說(shuo)肯定(ding)(ding)是直(zhi)接(jie)沖到(dao)袋(dai)(dai)子里(li)比(bi)較(jiao)好，這樣置(zhi)換的(de)(de)(de)又(you)純還(huan)能(neng)省(sheng)不少氣(qi)(qi)源(yuan)，但是大家一(yi)定(ding)(ding)要(yao)(yao)考慮好自己產(chan)品(pin)性(xing)質。如果(guo)產(chan)品(pin)是顆粒，我們可以(yi)采取起(qi)初(chu)一(yi)種(zhong)方法直(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)嘴到(dao)袋(dai)(dai)子里(li)進行充(chong)(chong)氣(qi)(qi)，但是如果(guo)你(ni)的(de)(de)(de)產(chan)品(pin)是粉(fen)末狀(zhuang)的(de)(de)(de)就(jiu)不能(neng)用(yong)(yong)起(qi)初(chu)一(yi)種(zhong)方法了，需(xu)要(yao)(yao)第二(er)種(zhong)在真空室(shi)充(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓(ya)力(li)差充(chong)(chong)滿袋(dai)(dai)子。可是客戶(hu)又(you)要(yao)(yao)要(yao)(yao)求(qiu)達到(dao)一(yi)定(ding)(ding)比(bi)例的(de)(de)(de)殘氧量，這就(jiu)很矛盾了。
