真空包裝機廠的(de)真(zhen)空包裝機增加充(chong)(chong)(chong)氣(qi)(qi)(qi)功能是有(you)兩(liang)種(zhong)方(fang)式，一(yi)種(zhong)是氣(qi)(qi)(qi)嘴直接伸到產品袋(dai)子里面(mian)進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)的(de)，另(ling)一(yi)種(zhong)是把要充(chong)(chong)(chong)的(de)氣(qi)(qi)(qi)體先(xian)充(chong)(chong)(chong)滿(man)整個真(zhen)空室，然后靠(kao)負壓差充(chong)(chong)(chong)滿(man)袋(dai)子。那究竟采(cai)用(yong)哪種(zhong)方(fang)式充(chong)(chong)(chong)氣(qi)(qi)(qi)好呢，這(zhe)里主要看客戶(hu)的(de)產品性(xing)質，單純(chun)來說(shuo)肯定(ding)(ding)是直接沖到袋(dai)子里比(bi)(bi)較好，這(zhe)樣置換的(de)又(you)純(chun)還能省(sheng)不(bu)少氣(qi)(qi)(qi)源，但是大家(jia)一(yi)定(ding)(ding)要考慮(lv)好自己(ji)產品性(xing)質。如果(guo)產品是顆粒(li)，我們可以采(cai)取起(qi)初(chu)一(yi)種(zhong)方(fang)法(fa)直接讓充(chong)(chong)(chong)氣(qi)(qi)(qi)嘴到袋(dai)子里進行(xing)充(chong)(chong)(chong)氣(qi)(qi)(qi)，但是如果(guo)你(ni)的(de)產品是粉末狀的(de)就(jiu)不(bu)能用(yong)起(qi)初(chu)一(yi)種(zhong)方(fang)法(fa)了，需要第二種(zhong)在真(zhen)空室充(chong)(chong)(chong)氣(qi)(qi)(qi)利(li)用(yong)壓力差充(chong)(chong)(chong)滿(man)袋(dai)子。可是客戶(hu)又(you)要要求達到一(yi)定(ding)(ding)比(bi)(bi)例的(de)殘氧量，這(zhe)就(jiu)很矛盾了。
