真空包裝機廠(chang)的(de)真(zhen)空包裝機增加充(chong)(chong)氣(qi)(qi)(qi)功能是(shi)有兩種(zhong)(zhong)(zhong)方式，一種(zhong)(zhong)(zhong)是(shi)氣(qi)(qi)(qi)嘴直接(jie)伸(shen)到產(chan)(chan)品(pin)袋(dai)子里面進行充(chong)(chong)氣(qi)(qi)(qi)的(de)，另一種(zhong)(zhong)(zhong)是(shi)把要充(chong)(chong)的(de)氣(qi)(qi)(qi)體(ti)先充(chong)(chong)滿(man)整個真(zhen)空室(shi)，然后靠(kao)負(fu)壓差(cha)(cha)充(chong)(chong)滿(man)袋(dai)子。那究竟采(cai)用哪種(zhong)(zhong)(zhong)方式充(chong)(chong)氣(qi)(qi)(qi)好呢，這里主(zhu)要看客戶(hu)的(de)產(chan)(chan)品(pin)性(xing)質，單純(chun)來說肯定(ding)是(shi)直接(jie)沖到袋(dai)子里比較好，這樣置(zhi)換的(de)又(you)純(chun)還能省不少氣(qi)(qi)(qi)源，但是(shi)大家一定(ding)要考慮好自己產(chan)(chan)品(pin)性(xing)質。如果產(chan)(chan)品(pin)是(shi)顆粒，我們可以(yi)采(cai)取(qu)起初一種(zhong)(zhong)(zhong)方法直接(jie)讓充(chong)(chong)氣(qi)(qi)(qi)嘴到袋(dai)子里進行充(chong)(chong)氣(qi)(qi)(qi)，但是(shi)如果你(ni)的(de)產(chan)(chan)品(pin)是(shi)粉末狀的(de)就不能用起初一種(zhong)(zhong)(zhong)方法了，需要第二種(zhong)(zhong)(zhong)在真(zhen)空室(shi)充(chong)(chong)氣(qi)(qi)(qi)利用壓力差(cha)(cha)充(chong)(chong)滿(man)袋(dai)子。可是(shi)客戶(hu)又(you)要要求達到一定(ding)比例(li)的(de)殘氧量，這就很矛盾了。
