真空包裝機(ji)廠的真(zhen)空包(bao)裝機增加充(chong)氣(qi)(qi)功能是(shi)(shi)(shi)(shi)(shi)有(you)兩種(zhong)(zhong)方(fang)式，一種(zhong)(zhong)是(shi)(shi)(shi)(shi)(shi)氣(qi)(qi)嘴(zui)直接(jie)伸到產(chan)(chan)品袋(dai)(dai)子(zi)里(li)面(mian)進(jin)行(xing)充(chong)氣(qi)(qi)的，另一種(zhong)(zhong)是(shi)(shi)(shi)(shi)(shi)把要(yao)充(chong)的氣(qi)(qi)體先充(chong)滿整個真(zhen)空室(shi)(shi)，然后靠(kao)負(fu)壓差充(chong)滿袋(dai)(dai)子(zi)。那究竟采(cai)用(yong)(yong)哪種(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)好(hao)呢(ni)，這里(li)主要(yao)看客戶(hu)的產(chan)(chan)品性(xing)質，單純來(lai)說肯定是(shi)(shi)(shi)(shi)(shi)直接(jie)沖(chong)到袋(dai)(dai)子(zi)里(li)比較好(hao)，這樣置(zhi)換的又純還(huan)能省不(bu)少氣(qi)(qi)源，但是(shi)(shi)(shi)(shi)(shi)大家一定要(yao)考慮好(hao)自己產(chan)(chan)品性(xing)質。如果產(chan)(chan)品是(shi)(shi)(shi)(shi)(shi)顆(ke)粒，我們可以采(cai)取起(qi)(qi)初(chu)一種(zhong)(zhong)方(fang)法直接(jie)讓充(chong)氣(qi)(qi)嘴(zui)到袋(dai)(dai)子(zi)里(li)進(jin)行(xing)充(chong)氣(qi)(qi)，但是(shi)(shi)(shi)(shi)(shi)如果你(ni)的產(chan)(chan)品是(shi)(shi)(shi)(shi)(shi)粉末(mo)狀的就不(bu)能用(yong)(yong)起(qi)(qi)初(chu)一種(zhong)(zhong)方(fang)法了，需(xu)要(yao)第(di)二(er)種(zhong)(zhong)在真(zhen)空室(shi)(shi)充(chong)氣(qi)(qi)利(li)用(yong)(yong)壓力差充(chong)滿袋(dai)(dai)子(zi)。可是(shi)(shi)(shi)(shi)(shi)客戶(hu)又要(yao)要(yao)求達到一定比例的殘氧量，這就很矛(mao)盾了。
