真空包裝機廠的(de)真空包裝(zhuang)機增加充(chong)(chong)氣(qi)(qi)功(gong)能是(shi)有(you)兩種(zhong)(zhong)(zhong)方(fang)式，一種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)伸到產(chan)(chan)品(pin)袋(dai)子里(li)面進(jin)行(xing)(xing)充(chong)(chong)氣(qi)(qi)的(de)，另(ling)一種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)(chong)的(de)氣(qi)(qi)體先(xian)充(chong)(chong)滿整(zheng)個真空室，然后(hou)靠負壓(ya)差(cha)充(chong)(chong)滿袋(dai)子。那究竟采用(yong)(yong)哪(na)種(zhong)(zhong)(zhong)方(fang)式充(chong)(chong)氣(qi)(qi)好呢，這里(li)主(zhu)要(yao)看客戶(hu)的(de)產(chan)(chan)品(pin)性(xing)質，單純(chun)來說肯(ken)定(ding)是(shi)直(zhi)接(jie)沖到袋(dai)子里(li)比較好，這樣置換的(de)又(you)(you)純(chun)還(huan)能省不(bu)少氣(qi)(qi)源(yuan)，但是(shi)大家一定(ding)要(yao)考(kao)慮好自己(ji)產(chan)(chan)品(pin)性(xing)質。如(ru)果產(chan)(chan)品(pin)是(shi)顆粒，我們可以采取起初一種(zhong)(zhong)(zhong)方(fang)法直(zhi)接(jie)讓充(chong)(chong)氣(qi)(qi)嘴(zui)到袋(dai)子里(li)進(jin)行(xing)(xing)充(chong)(chong)氣(qi)(qi)，但是(shi)如(ru)果你的(de)產(chan)(chan)品(pin)是(shi)粉末狀的(de)就不(bu)能用(yong)(yong)起初一種(zhong)(zhong)(zhong)方(fang)法了，需要(yao)第二種(zhong)(zhong)(zhong)在真空室充(chong)(chong)氣(qi)(qi)利用(yong)(yong)壓(ya)力差(cha)充(chong)(chong)滿袋(dai)子。可是(shi)客戶(hu)又(you)(you)要(yao)要(yao)求達到一定(ding)比例(li)的(de)殘氧量，這就很(hen)矛盾了。
