真空(kong)包裝(zhuang)機廠的(de)(de)真空(kong)包裝機增(zeng)加充(chong)氣(qi)功能是(shi)有(you)兩種(zhong)(zhong)(zhong)方式(shi)(shi)，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)嘴(zui)直接(jie)伸到產(chan)品(pin)(pin)袋(dai)子里(li)面進行(xing)充(chong)氣(qi)的(de)(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把要(yao)(yao)(yao)充(chong)的(de)(de)氣(qi)體先充(chong)滿(man)整個真空(kong)室，然后靠負壓差(cha)充(chong)滿(man)袋(dai)子。那究竟采(cai)用(yong)哪種(zhong)(zhong)(zhong)方式(shi)(shi)充(chong)氣(qi)好呢，這里(li)主要(yao)(yao)(yao)看客(ke)戶(hu)的(de)(de)產(chan)品(pin)(pin)性質(zhi)(zhi)，單純(chun)來說肯定(ding)是(shi)直接(jie)沖(chong)到袋(dai)子里(li)比(bi)(bi)較好，這樣置換(huan)的(de)(de)又(you)純(chun)還(huan)能省不少氣(qi)源(yuan)，但是(shi)大家一(yi)定(ding)要(yao)(yao)(yao)考慮好自(zi)己(ji)產(chan)品(pin)(pin)性質(zhi)(zhi)。如果產(chan)品(pin)(pin)是(shi)顆粒，我們可以采(cai)取起初一(yi)種(zhong)(zhong)(zhong)方法(fa)直接(jie)讓充(chong)氣(qi)嘴(zui)到袋(dai)子里(li)進行(xing)充(chong)氣(qi)，但是(shi)如果你(ni)的(de)(de)產(chan)品(pin)(pin)是(shi)粉末狀(zhuang)的(de)(de)就(jiu)(jiu)不能用(yong)起初一(yi)種(zhong)(zhong)(zhong)方法(fa)了(le)(le)，需要(yao)(yao)(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室充(chong)氣(qi)利(li)用(yong)壓力(li)差(cha)充(chong)滿(man)袋(dai)子。可是(shi)客(ke)戶(hu)又(you)要(yao)(yao)(yao)要(yao)(yao)(yao)求達到一(yi)定(ding)比(bi)(bi)例的(de)(de)殘(can)氧量，這就(jiu)(jiu)很矛(mao)盾了(le)(le)。
