真空包裝機廠的(de)(de)真空(kong)包裝機增加充(chong)氣(qi)(qi)功能(neng)是(shi)有兩(liang)種(zhong)(zhong)(zhong)方(fang)(fang)式，一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)嘴(zui)直(zhi)接(jie)(jie)伸到產(chan)品(pin)袋(dai)(dai)(dai)(dai)子里面進行(xing)充(chong)氣(qi)(qi)的(de)(de)，另一(yi)(yi)種(zhong)(zhong)(zhong)是(shi)把要(yao)充(chong)的(de)(de)氣(qi)(qi)體(ti)先充(chong)滿(man)整(zheng)個真空(kong)室(shi)，然后靠負壓(ya)(ya)差充(chong)滿(man)袋(dai)(dai)(dai)(dai)子。那(nei)究竟(jing)采(cai)用(yong)哪種(zhong)(zhong)(zhong)方(fang)(fang)式充(chong)氣(qi)(qi)好呢(ni)，這(zhe)里主要(yao)看客戶的(de)(de)產(chan)品(pin)性質(zhi)，單(dan)純來說(shuo)肯(ken)定(ding)是(shi)直(zhi)接(jie)(jie)沖到袋(dai)(dai)(dai)(dai)子里比(bi)較好，這(zhe)樣置換的(de)(de)又(you)純還能(neng)省不少氣(qi)(qi)源，但(dan)是(shi)大家一(yi)(yi)定(ding)要(yao)考慮(lv)好自己產(chan)品(pin)性質(zhi)。如果產(chan)品(pin)是(shi)顆粒，我(wo)們可以采(cai)取起初(chu)一(yi)(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法直(zhi)接(jie)(jie)讓充(chong)氣(qi)(qi)嘴(zui)到袋(dai)(dai)(dai)(dai)子里進行(xing)充(chong)氣(qi)(qi)，但(dan)是(shi)如果你的(de)(de)產(chan)品(pin)是(shi)粉末狀的(de)(de)就不能(neng)用(yong)起初(chu)一(yi)(yi)種(zhong)(zhong)(zhong)方(fang)(fang)法了，需要(yao)第二種(zhong)(zhong)(zhong)在真空(kong)室(shi)充(chong)氣(qi)(qi)利用(yong)壓(ya)(ya)力(li)差充(chong)滿(man)袋(dai)(dai)(dai)(dai)子。可是(shi)客戶又(you)要(yao)要(yao)求達到一(yi)(yi)定(ding)比(bi)例(li)的(de)(de)殘氧(yang)量，這(zhe)就很矛(mao)盾了。
