真空包裝(zhuang)機廠(chang)的(de)(de)(de)真(zhen)(zhen)空(kong)包(bao)裝機增加充(chong)氣(qi)(qi)(qi)功能是(shi)有(you)兩(liang)種(zhong)(zhong)(zhong)方(fang)式，一(yi)種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)嘴(zui)直接(jie)(jie)(jie)伸(shen)到(dao)產(chan)(chan)品袋(dai)子里面進行(xing)充(chong)氣(qi)(qi)(qi)的(de)(de)(de)，另一(yi)種(zhong)(zhong)(zhong)是(shi)把要(yao)(yao)充(chong)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)先充(chong)滿整個真(zhen)(zhen)空(kong)室(shi)，然后靠負(fu)壓(ya)差充(chong)滿袋(dai)子。那究竟采用(yong)(yong)哪種(zhong)(zhong)(zhong)方(fang)式充(chong)氣(qi)(qi)(qi)好呢，這(zhe)(zhe)里主(zhu)要(yao)(yao)看客戶(hu)的(de)(de)(de)產(chan)(chan)品性(xing)質，單純(chun)來說(shuo)肯定(ding)是(shi)直接(jie)(jie)(jie)沖(chong)到(dao)袋(dai)子里比(bi)較(jiao)好，這(zhe)(zhe)樣置(zhi)換的(de)(de)(de)又純(chun)還能省不少氣(qi)(qi)(qi)源，但是(shi)大家(jia)一(yi)定(ding)要(yao)(yao)考慮好自己產(chan)(chan)品性(xing)質。如果(guo)產(chan)(chan)品是(shi)顆粒，我們可(ke)以(yi)采取起初一(yi)種(zhong)(zhong)(zhong)方(fang)法直接(jie)(jie)(jie)讓充(chong)氣(qi)(qi)(qi)嘴(zui)到(dao)袋(dai)子里進行(xing)充(chong)氣(qi)(qi)(qi)，但是(shi)如果(guo)你的(de)(de)(de)產(chan)(chan)品是(shi)粉末狀的(de)(de)(de)就不能用(yong)(yong)起初一(yi)種(zhong)(zhong)(zhong)方(fang)法了，需要(yao)(yao)第二(er)種(zhong)(zhong)(zhong)在真(zhen)(zhen)空(kong)室(shi)充(chong)氣(qi)(qi)(qi)利用(yong)(yong)壓(ya)力差充(chong)滿袋(dai)子。可(ke)是(shi)客戶(hu)又要(yao)(yao)要(yao)(yao)求達到(dao)一(yi)定(ding)比(bi)例(li)的(de)(de)(de)殘氧量，這(zhe)(zhe)就很矛盾了。
